I'm trying to implement authentication with Spring Security and my problem is that I'm using a MongoDB base where the username and the associated password are in two distinct collections. So when I implement UserDetails, I can't return the password properly. Here is what I've tried:
package com.example.springmongo.user;
import java.util.Collection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
#Document(collection = "users")
public class User implements UserDetails {
/**
*
*/
private static final long serialVersionUID = -2217225560457250699L;
#Autowired
private UserPassService userPassService;
#Id
private String id;
#Field(value = "iduser")
private Long iduser;
#Field(value = "name_complete")
private String name_complete;
#Field(value = "mail")
private String mail;
#Field(value = "active")
private Double active;
#Field(value = "creationDate")
private String creationDate;
#Field(value = "last_login")
private String last_login;
public User() {
super();
}
public User(String id, Long iduser, String name_complete, String mail, Double active, String creationDate, String last_login) {
super();
this.id = id;
this.iduser = iduser;
this.name_complete = name_complete;
this.mail = mail;
this.active = active;
this.creationDate = creationDate;
this.last_login = last_login;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Long getIduser() {
return iduser;
}
public void setIduser(Long iduser) {
this.iduser = iduser;
}
public String getName_complete() {
return name_complete;
}
public void setName_complete(String name_complete) {
this.name_complete = name_complete;
}
public String getMail() {
return mail;
}
public void setMail(String mail) {
this.mail = mail;
}
public Double getActive() {
return active;
}
public void setActive(Double active) {
this.active = active;
}
public String getCreationDate() {
return creationDate;
}
public void setCreationDate(String creationDate) {
this.creationDate = creationDate;
}
public String getLast_login() {
return last_login;
}
public void setLast_login(String last_login) {
this.last_login = last_login;
}
#Override
public String toString() {
return "name: " + this.name_complete + ", mail: " + this.mail + ", id: " + this.id;
}
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
// TODO Auto-generated method stub
return null;
}
#Override
public String getPassword() {
return this.userPassService.getUserPassword(this.iduser);
}
#Override
public String getUsername() {
return this.getMail();
}
#Override
public boolean isAccountNonExpired() {
if (this.getActive() != null && this.getActive().equals(1.0)) {
return true;
}
return false;
}
#Override
public boolean isAccountNonLocked() {
if (this.getActive() != null && this.getActive().equals(1.0)) {
return true;
}
return false;
}
#Override
public boolean isCredentialsNonExpired() {
if (this.getActive() != null && this.getActive().equals(1.0)) {
return true;
}
return false;
}
#Override
public boolean isEnabled() {
if (this.getActive() != null && this.getActive().equals(1.0)) {
return true;
}
return false;
}
}
Unfortunately, I can't access my UserPassService from an entity like this. So how can I access the password ?
Thanks in advance !
You cant use #Autowired on spring components in entity class as a field. Use like this ;
private transient UserPassService userPassService;
and add setter method of this ;
#Autowired
public void setUserPassService(UserPassService userPassService) {
this.userPassService = userPassService;
}
Beaware of creatation of Entity class with new is making this service is null. If you create with new , call setUserPassService method with autowired object of UserPassService.

and im trying to getID and use that in another call. This is an object that I am trying to turn into an integer an then use that in a seperate call again.
referralResponseResponse = call1.getReferral(token).execute();
int i = (int) referralResponseResponse.body().getId();
System.out.println("Int: " + i);
I should also note the json that I'm using this data from is very large so ive just used jsonpogo to extract this information to a java file and then use the parts that apply to me, I dont imagine i have to set up a java class for every part of the retruned json
Try to add following annotation for your POJO class:
#JsonIgnoreProperties(ignoreUnknown = true)
In the mysql database, the transaction table has successfully had the accountId field added via Java code. However, whenever I add a transaction on the React frontend, the account_id column value in the database is null. What could I be doing wrong?

Relevant React code from the transactions form:
let username = AuthenticationService.getLoggedInUsername();
fetch(`http://localhost:8080/jpa/users/${username}/transactions`, {
method: "POST",
body: JSON.stringify({
accountId: this.state.accountId,
transactionDate: this.state.transactionDate,
transactionType: this.state.transactionType,
depositCategory: this.state.depositCategory,
withdrawalCategory: this.state.withdrawalCategory,

}),
headers: {

})
.then((result) => result.text())
.then((data) => console.log(data));
};
...
handleAccountNameChange = (event) => {
this.setState({ accountId: event.target.value });
};
This is what I did to fix the issue:
In React, in the transactions form:
fetch(`http://localhost:8080/jpa/users/${username}/transactions`, {
method: "POST",
body: JSON.stringify({
username: this.state.username,
transactionDate: this.state.transactionDate,

account: ({
id: this.state.accountId,
username: this.state.username,
accountName: this.state.accountName,
asOfDate: this.state.asOfDate
})
}),
In the Account entity:
#Entity
#Table(name = "account")
public class Account {

#GeneratedValue

private String username;

private Date asOfDate;
#OneToMany(mappedBy = "account", cascade = { CascadeType.PERSIST, CascadeType.ALL, CascadeType.MERGE })

In the Transaction entity:

Transaction createdTransaction = transactionJpaRepository.save(transaction);
URI uri = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}")
.buildAndExpand(createdTransaction.getId()).toUri();
ResponseEntity<Object> build = ResponseEntity.created(uri).build();
int statusCodeValue = build.getStatusCodeValue();
if (build.getStatusCodeValue() == 201) {

This is my 1st project in Java/Hibernate.
I m trying to join two tables but even after searching a lot, I couldn't find the proper solution to achieve what i want.
Let me explain you what i have currently.
I have two entities:
#Entity
#Table(name = "admin")
public class AdminLogin {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String firstName;
private String lastName;
private String username;
private String password;
private String status;
private String userRole;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getUserRole() {
return userRole;
}
public void setUserRole(String userRole) {
this.userRole = userRole;
}
}
#Entity
#Table(name = "user_balance_log")
public class UserBalanceLog {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int userId;
private int adminId;
private Float balance;
private String balanceType;
private String message;
#Temporal(javax.persistence.TemporalType.DATE)
private Date dateCreated;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public int getAdminId() {
return adminId;
}
public void setAdminId(int adminId) {
this.adminId = adminId;
}
public Float getBalance() {
return balance;
}
public void setBalance(Float balance) {
this.balance = balance;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Date getDateCreated() {
return dateCreated;
}
public void setDateCreated(Date dateCreated) {
this.dateCreated = dateCreated;
}
public String getBalanceType() {
return balanceType;
}
public void setBalanceType(String balanceType) {
this.balanceType = balanceType;
}
}
I want to join the adminId from User Balance Log Entity to Admin Login Entity.
This is what i have currently.
Session session = this.sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(UserBalanceLog.class, "ubl");
criteria.setProjection(Projections.projectionList().add(Projections.property("balance"),"balance").add(Projections.property("balanceType"),"balanceType").add(Projections.property("message"),"message").add(Projections.property("dateCreated"),"dateCreated"));
criteria.addOrder(Order.desc("id"));
if (parameters.get("userId") != null) {
criteria.add(Restrictions.eq("userId", new Integer(parameters.get("userId"))));
}
if (parameters.get("balanceType") != null) {
criteria.add(Restrictions.eq("balanceType", parameters.get("balanceType")));
}
if (parameters.get("dateCreated") != null) {
criteria.add(Restrictions.eq("dateCreated", parameters.get("dateCreated")));
}
List userBalanceList = criteria.list();
Please guide me.
Thanks
Finally i figured it out myself of course with the help/guidance of #vc73.
This is the updation i had to do in model:
#Entity
#Table(name = "user_balance_log")
public class UserBalanceLog {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int userId;
#ManyToOne
#JoinColumn(name="adminId")
private AdminLogin adminId;
private Float balance;
private String balanceType;
private String message;
#Temporal(javax.persistence.TemporalType.DATE)
private Date dateCreated;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public AdminLogin getAdminId() {
return adminId;
}
public void setAdminId(AdminLogin adminId) {
this.adminId = adminId;
}
public Float getBalance() {
return balance;
}
public void setBalance(Float balance) {
this.balance = balance;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Date getDateCreated() {
return dateCreated;
}
public void setDateCreated(Date dateCreated) {
this.dateCreated = dateCreated;
}
public String getBalanceType() {
return balanceType;
}
public void setBalanceType(String balanceType) {
this.balanceType = balanceType;
}
}
and in the DAO:
Session session = this.sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(UserBalanceLog.class, "ubl");
criteria.createAlias("ubl.adminId", "a");
criteria.setProjection(Projections.projectionList().add(Projections.property("balance").as("balance")).add(Projections.property("balanceType").as("balanceType")).add(Projections.property("message").as("message")).add(Projections.property("dateCreated").as("dateCreated")).add(Projections.property("a.username").as("username")));
criteria.addOrder(Order.desc("id"));
if (parameters.get("userId") != null) {
criteria.add(Restrictions.eq("userId", new Integer(parameters.get("userId"))));
}
if (parameters.get("balanceType") != null) {
criteria.add(Restrictions.eq("balanceType", parameters.get("balanceType")));
}
if (parameters.get("dateCreated") != null) {
criteria.add(Restrictions.eq("dateCreated", parameters.get("dateCreated")));
}
criteria.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);
criteria.setFirstResult(start);
criteria.setMaxResults(Pagination.limitPerPage);
List userBalanceList = criteria.list();
I hope it will help someone else.
I am currently developing a Java EE application using hibernate as ORM.
I am using the DAO design pattern. I want to delete a row from the contact table but I don't know why it is not working. When I delete société it works.
I have a relation between société and contact. When a contact has idSociéte=null it is deleted, but if it exist it will not delete it. When I did delete in phpmysadmin it works even if idSociété not null.

when a contact has idSociéte=null it is deleted but if it exist it
will not delete it.
It means if the idSociete is not null and have some value for eg. 123. You need to check if any of the contact have the same idSociete. if it's present with any other contact then your contact will not be deleted as Many contacts can be associated with same société. Try with single contact and a single société associated with it.

So, while displaying data into the grid like table.addColumn(SitePantryResponse::getSiteData::getName).setCaption("Site Name") it throws:
The target type of this expression must be a functional interface` error.
SitePantryResponse::getSiteData::getName
It's not possible to chain method references like that. You can use simple lambda expression instead:
table.addColumn(r -> r.getSideDate().getName()).setCaption("Site Name")
or if you really want to use method references, you can use a helper method which will chain them and return ValueProvider which can be later passed to Grid.addColumn:
<A, B, C> ValueProvider<A, C> chain(Function<A, B> f1, Function<B, C> f2) {
return f1.andThen(f2)::apply;
}
With this you can write:
table.addColumn(chain(SitePantryResponse::getSiteData, SiteResponse::getName)).setCaption("Site Name")
but, as you can see, this makes the code more complicated and longer, so there is no reason to use this approach over simple lambda expression.
