How to enable auditing for MongoDB via Annotations in Spring

How to enable auditing for MongoDB via Annotations in Spring - java

I wanted to enable some auditing features, such as #CreatedDate. I am not using Spring xml configuration file, so I cannot add mongo:auditing to Spring configuration. I was wondering if there was an alternative way of enable auditing. The following code is the model for user. But whenever I create a user, the date is not stored in the document, so the auditing it's not working. Could someone give me some help?
#Document(collection = "user")
public class User {
#Id
private String id;
#Indexed(unique = true)
private String email;
private String name;
#CreatedDate
private Date date;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}

Because you are not using configuration via XML, I believe you are using annotations. You own a class like this:
public class MongoConfig extends AbstractMongoConfiguration {...}
Thus, in addition to the annotations you should already have, add: #EnableMongoAuditing
Your configuration class will look like this now:
#Configuration
#EnableMongoRepositories(basePackages="...")
#EnableMongoAuditing
public class MongoConfig extends AbstractMongoConfiguration {...}
I hope this helps!

That's all you need. No subclasses or other stuff.
#Configuration
#EnableMongoAuditing
public class AnyConfig {}

You should write a configuration class in which you can connect to MongoDB database using mongoClient by passing db url. and add the anootaion of #EnableMongoAuditing on top of that class.

rest api return duplicate values in postman and spring boot h2

I am new spring boot developer and i am trying to develope and rest api . when I do it ,I get and issues that my api return two duplicated response in postman .But i haven't code anythiong to get duplicated valuese in my code . the one of duplicate values is my model clase variable and athor one is table's attribute name .
below response in postman
model class
public class person {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY )
private Long id;
#Column(name = "name")
private String Name ;
#Column(name ="surname")
private String Surname;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getSurname() {
return Surname;
}
public void setSurname(String surname) {
Surname = surname;
}
}
repository

The problem is that you're not following the proper conventions in your naming strategy.
Due to this, Jackson doesn't know that your getters (getSurname(), getName()) are referencing the fields Surname and Name. That's why it serializes both your fields and your getters separately to JSON.
To fix this, you can follow the Java naming conventions and use a lowercase letter for the first character of your fields.
For example:
#Column(name = "name")
private String name; // Change this
#Column(name ="surname")
private String surname; // Change this
This will change your JSON output to:
{
"id": 1,
"name": "bryan",
"surname": "Nicky"
}
If you want to keep your JSON with capital letters, you can use the #JsonProperty annotation:
#JsonProperty("Name") // Add this
#Column(name = "name")
private String name;
#JsonProperty("Surname") // Add this
#Column(name ="surname")
private String surname;
Unrelated to your question, but according to those naming conventions, your classes should start with a capital (eg. Person, PersonController, PersonRepository, ...).

How to fix unsatisfied dependencies for injecting Models (javax.mvc.Models)?

I get this error while following this tutorial for mvc 1.0.
[ERROR] Caused by: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type Models with qualifiers #Default at injection point [BackedAnnotatedField] #Inject ch.xxx.controller.UserController.models at ch.xxx.controller.UserController.models(UserController.java:0)
I tried...
putting my beans.xml into multiple places (resources/META-INF/beans.xml | webapp/WEB-INF/beans.xml)
changing the bean-discovery-mode to "all"
annotated my User.class with #Named and/or #SessionScoped (not in tutorial)
This is my User.class
#Entity
#Table(name = "users")
#NamedQuery(name = "User.findAll", query = "SELECT u FROM User u")
public class User implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
private String email;
private String password;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Here my UserForm.class
import javax.ws.rs.FormParam;
public class UserForm {
#FormParam("id")
private String id;
#FormParam("email")
private String email;
#FormParam("password")
private String password;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
and at last my UserController.class, where the error actually happens:
#Controller
#Stateless
#Path("/user")
public class UserController {
#PersistenceContext
EntityManager entityManager;
#Inject
Models models;
#GET
#View("user/all-users.html")
public void getAllREST(){
List<User> allUsers = entityManager.createNamedQuery("User.findAll", User.class).getResultList();
models.put("users", allUsers);
}
#GET
#Path("/create")
public String getCreateRESTForm(){
return "user/create-user.html";
}
#POST
#Path("/create")
public String create(#BeanParam UserForm userForm){
User user = new User();
user.setEmail(userForm.getEmail());
user.setPassword(user.getPassword());
entityManager.persist(user);
return "redirect:/user";
}
}
I'm really lost here, since I have no idea what more to change and what the actual problem is for such a simple form. And don't mind the plain text password, it's just for testing.

I have not worked with JEE MVC yet but this seems to be CDI related issue and should not be located in the MVC framework, because it should only make use of CDI.
The reason for this exception, as already answered, is because the CDI Container does not find any injectible implementations of this interface, and therefore cannot inject it.
Take a look at the javadoc which says, that any implementation of this interface needs to be injectible and request scoped. Are you sure that the implementing bean you expect fulfills these requirements?
https://github.com/javaee/mvc-spec/blob/master/api/src/main/java/javax/mvc/Models.java
Is there a beans.xml present in the artifact the bean resides?
src/main/reosurces/META-INF/beans.xml (for JAR)
src/main/webapp/WEB-INF/beans.xml (for WAR)
Is the implementing bean annotated with #RequestScoped?
If referenced via EL, is the bean annotated with #Named?
Another thing is, do not make JPA entities CDI-Beans and make them injectible, this is a bad approach and the Models interfaces and its implementations should not require it.

Cant Post directly to sub-resouce in spring boot data rest

I have a basic spring boot data rest api with posts that can have many comments. My problem is that I cant seem to find a way to post my comment directly to the sub resource uri such as http://localhost:8090/posts/1/comments.
The only way I've been able to do it was to to create the comment resource first at http://localhost:8090/comments and then post the uri of comment into http://localhost:8090/posts/1/comments.
It seems like a really bad idea as comments should never be able to exist on their own and only ever linked to a post.
Does anybody know how I can do this as one action, otherwise I'll have to manually deal with potential orphaned comments where the comment gets posted but never gets posted into http://localhost:8090/posts/1/comments for whatever reason.
My code is below.
Any help would be massively appreciated.
#Entity
public class Comment extends ResourceSupport {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#JsonIgnore
private Long id;
private String comment;
#ManyToOne
private Post post;
#ManyToOne
private User sender;
protected Comment() {};
public void setId(Long id) {
this.id = id;
}
public String getComment() {
return comment;
}
public void setComment(String comment) {
this.comment = comment;
}
public User getSender() {
return sender;
}
public void setSender(User sender) {
this.sender = sender;
}
public Post getPost() {
return post;
}
public void setPost(Post post) {
this.post = post;
}
#Entity
public class Post extends ResourceSupport {
#Id
#GeneratedValue(strategy= GenerationType.AUTO)
private #JsonIgnore Long id;
private String text;
#OneToMany
private List<Comment> comments;
protected Post () {};
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public List<Comment> getComments() {
return comments;
}
public void setComments(List<Comment> comments) {
this.comments = comments;
}
}
#RepositoryRestResource
public interface PostRepository extends PagingAndSortingRepository<Post, Long> {}
#RepositoryRestResource
public interface CommentRepository extends PagingAndSortingRepository<Comment, Long> {}
#SpringBootApplication
#EnableJpaRepositories("rest.api.repository")
#EnableWebMvc
#EnableTransactionManagement
#EnableAutoConfiguration
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
the json im using to try to post the comment into the post is
{
"comment": "some text",
"sender": "http://localhost:8090/users/1"
}

It turned out that i needed to use mapped by i.e. #OneToMany(mappedBy = "post") on my comments list in my Post class.
Now i can post to http://localhost:8090/comments and then when i follow the http://localhost:8090/posts/1/comments link as before i now see the comments.

Id property is missing in the reponse of a RestAPI call [duplicate]

Have a strange problem and can't figure out how to deal with it.
Have simple POJO:
#Entity
#Table(name = "persons")
public class Person {
#Id
#GeneratedValue
private Long id;
#Column(name = "first_name")
private String firstName;
#Column(name = "middle_name")
private String middleName;
#Column(name = "last_name")
private String lastName;
#Column(name = "comment")
private String comment;
#Column(name = "created")
private Date created;
#Column(name = "updated")
private Date updated;
#PrePersist
protected void onCreate() {
created = new Date();
}
#PreUpdate
protected void onUpdate() {
updated = new Date();
}
#Valid
#OrderBy("id")
#OneToMany(mappedBy = "person", fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval = true)
private List<PhoneNumber> phoneNumbers = new ArrayList<>();
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getComment() {
return comment;
}
public void setComment(String comment) {
this.comment = comment;
}
public Date getCreated() {
return created;
}
public Date getUpdated() {
return updated;
}
public List<PhoneNumber> getPhoneNumbers() {
return phoneNumbers;
}
public void addPhoneNumber(PhoneNumber number) {
number.setPerson(this);
phoneNumbers.add(number);
}
#Override
public String toString() {
return ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE);
}
}
#Entity
#Table(name = "phone_numbers")
public class PhoneNumber {
public PhoneNumber() {}
public PhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
#Id
#GeneratedValue
private Long id;
#Column(name = "phone_number")
private String phoneNumber;
#ManyToOne
#JoinColumn(name = "person_id")
private Person person;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
#Override
public String toString() {
return ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE);
}
}
and rest endpoint:
#ResponseBody
#RequestMapping(method = RequestMethod.GET)
public List<Person> listPersons() {
return personService.findAll();
}
In json response there are all fields except Id, which I need on front end side to edit/delete person. How can I configure spring boot to serialize Id as well?
That's how response looks like now:
[{
"firstName": "Just",
"middleName": "Test",
"lastName": "Name",
"comment": "Just a comment",
"created": 1405774380410,
"updated": null,
"phoneNumbers": [{
"phoneNumber": "74575754757"
}, {
"phoneNumber": "575757547"
}, {
"phoneNumber": "57547547547"
}]
}]
UPD Have bidirectional hibernate mapping, maybe it's somehow related to issue.

I recently had the same problem and it's because that's how spring-boot-starter-data-rest works by default. See my SO question -> While using Spring Data Rest after migrating an app to Spring Boot, I have observed that entity properties with #Id are no longer marshalled to JSON
To customize how it behaves, you can extend RepositoryRestConfigurerAdapter to expose IDs for specific classes.
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter;
#Configuration
public class RepositoryConfig extends RepositoryRestConfigurerAdapter {
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(Person.class);
}
}

In case you need to expose the identifiers for all entities:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurer;
import javax.persistence.EntityManager;
import javax.persistence.metamodel.Type;
#Configuration
public class RestConfiguration implements RepositoryRestConfigurer {
#Autowired
private EntityManager entityManager;
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(
entityManager.getMetamodel().getEntities().stream()
.map(Type::getJavaType)
.toArray(Class[]::new));
}
}
Note that in versions of Spring Boot prior to 2.1.0.RELEASE you must extend the (now deprecated) org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter instead of implement RepositoryRestConfigurer directly.
If you only want to expose the identifiers of entities that extends or
implements specific super class or interface:
...
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(
entityManager.getMetamodel().getEntities().stream()
.map(Type::getJavaType)
.filter(Identifiable.class::isAssignableFrom)
.toArray(Class[]::new));
}
If you only want to expose the identifiers of entities with a specific annotation:
...
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(
entityManager.getMetamodel().getEntities().stream()
.map(Type::getJavaType)
.filter(c -> c.isAnnotationPresent(ExposeId.class))
.toArray(Class[]::new));
}
Sample annotation:
import java.lang.annotation.*;
#Target(ElementType.TYPE)
#Retention(RetentionPolicy.RUNTIME)
public #interface ExposeId {}

Answer from #eric-peladan didn't work out of the box, but was pretty close, maybe that worked for previous versions of Spring Boot. Now this is how it is supposed to be configured instead, correct me if I'm wrong:
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter;
#Configuration
public class RepositoryConfiguration extends RepositoryRestConfigurerAdapter {
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(User.class);
config.exposeIdsFor(Comment.class);
}
}

The class RepositoryRestConfigurerAdapter has been deprecated since 3.1, implement RepositoryRestConfigurer directly.
#Configuration
public class RepositoryConfiguration implements RepositoryRestConfigurer {
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(YouClass.class);
RepositoryRestConfigurer.super.configureRepositoryRestConfiguration(config);
}
}
Font: https://docs.spring.io/spring-data/rest/docs/current-SNAPSHOT/api/org/springframework/data/rest/webmvc/config/RepositoryRestConfigurer.html

With Spring Boot you have to extends SpringBootRepositoryRestMvcConfiguration
if you use RepositoryRestMvcConfiguration the configuration define in application.properties may not worked
#Configuration
public class MyConfiguration extends SpringBootRepositoryRestMvcConfiguration {
#Override
protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(Project.class);
}
}
But for a temporary need
You can use projection to include id in the serialization like :
#Projection(name = "allparam", types = { Person.class })
public interface ProjectionPerson {
Integer getIdPerson();
String getFirstName();
String getLastName();
}

Just add #JsonProperty annotation to the Id and it works.
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#JsonProperty
private long id;
another approach is to implement RepositoryRestConfigurerAdapter in configuration. (This approach will be usefull when you have to do marshalling in many places)

#Component
public class EntityExposingIdConfiguration extends RepositoryRestConfigurerAdapter {
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
try {
Field exposeIdsFor = RepositoryRestConfiguration.class.getDeclaredField("exposeIdsFor");
exposeIdsFor.setAccessible(true);
ReflectionUtils.setField(exposeIdsFor, config, new ListAlwaysContains());
} catch (NoSuchFieldException e) {
e.printStackTrace();
}
}
class ListAlwaysContains extends ArrayList {
#Override
public boolean contains(Object o) {
return true;
}
}
}

Hm, ok seems like I found the solution. Removing spring-boot-starter-data-rest from pom file and adding #JsonManagedReference to phoneNumbers and #JsonBackReference to person gives desired output. Json in response isn't pretty printed any more but now it has Id. Don't know what magic spring boot performs under hood with this dependency but I don't like it :)

Easy way: rename your variable private Long id; to private Long Id;
Works for me. You can read more about it here

Implement the RepositoryRestConfigurer and use #Configuration annotation on the class.
Here's the snippet
#Configuration
public class BasicConfig implements RepositoryRestConfigurer{
#Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config, CorsRegistry cors) {
// TODO Auto-generated method stub
config.exposeIdsFor(Person.class);
}
}

You can also use the static configuration method to easily enable exposing ids in a few lines.
From the Spring Data Rest RepsositoryRestConfigurer docs:
static RepositoryRestConfigurer withConfig(Consumer<RepositoryRestConfiguration> consumer)
Convenience method to easily create simple RepositoryRestConfigurer instances that solely want to tweak the RepositoryRestConfiguration.
Parameters:
consumer - must not be null.
Since:
3.1
So this works for me in an existing #Configuration-annotated class:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurer;
#Configuration
public class ApplicationConfiguration {
#Bean
public RepositoryRestConfigurer repositoryRestConfigurer() {
return RepositoryRestConfigurer.withConfig(repositoryRestConfiguration ->
repositoryRestConfiguration.exposeIdsFor(Person.class)
);
}
}

Spring Data : Java configuration for MongoDB without XML

I tried the Spring Guide Accessing Data with MongoDB. What I can't figure out is how do I configure my code to not use the default server address and not use the default database. I have seen many ways to do it with XML but I am trying to stay with fully XML-less configurations.
Does anyone have an example that sets the server and database without XML and can be easily integrated into the sample they show in the Spring Guide?
Note: I did find how to set the collection (search for the phrase "Which collection will my documents be saved into " on this page.
Thank you!
p.s. same story with the Spring Guide for JPA -- how do you configure the db properties -- but that is another post :)

It would be something like this for a basic configuration :
#Configuration
#EnableMongoRepositories
public class MongoConfiguration extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "dataBaseName";
}
#Override
public Mongo mongo() throws Exception {
return new MongoClient("127.0.0.1", 27017);
}
#Override
protected String getMappingBasePackage() {
return "foo.bar.domain";
}
}
Example for a document :
#Document
public class Person {
#Id
private String id;
private String name;
public Person(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Example for a repository :
#Repository
public class PersonRepository {
#Autowired
MongoTemplate mongoTemplate;
public long countAllPersons() {
return mongoTemplate.count(null, Person.class);
}
}
