I am getting the exception
org.hibernate.MappingException: Unknown entity com.pro.entity.User
I have seen similar posts but almost all of them provides solution to change #Entity annotation to javax.persistence instead of hibernate. Which in my case wasn't useful as I am using correct annotation since the beginning. Here's the code for entity class dao and servlet context.
package com.pro.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="user")
public class User {
private static final long serialVersionUID = 1L;
#Id
#Column(name="userid")
#GeneratedValue(strategy=GenerationType.IDENTITY)
private String id;
#Column(name="password")
private String password;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Dao class code:
public User getUser(String userid)
{
Session session = this.sessionFactory.getCurrentSession();
User user = (User)session.load(User.class, userid);
return user;
}

It is because you are giving entity name in your Customer Entity,thus, same should be used in your queries(now name of the class cannot be referred in your queries). Try invoking the query with the same entity name mentioned(take care of cases as well).
Try as follows:
Query<Customer> theQuery=
currentSession.createQuery("from customer", Customer.class);
Here I have matched the entity name mentioned in #Entity(name="customer") in your query.
I didnt go through all your code but, in sessionFactory bean of xml,
Try changing <property name="packagesToScan" value="com.luv2code.springdemo.entity" /> to <property name="packagesToScan" value="code.luv2code.springdemo.entity" />.
Your actual Customer entity lives in package code.luv2code.springdemo.entity
, though you have used com.luv2code.springdemo.entity. So it is scanning wrong package. This might be the problem.
if you are using check if the packages of C3p0 of correct for hibernate, Iam using the following and it works for me.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>5.4.26.Final</version>
</dependency>
Also in contrast to the above answers, In Hibernate it is always the entity name for HQL even though you have added #Table(name="customer")
Query<Customer> theQuery=
currentSession.createQuery("from Customer", Customer.class);
Let me know if this still does not work for you
Try like this :
Query theQuery=currentSession.createQuery("from Customer");
In Customer class
#Entity --> hibernate takes by Default as #Entity(name = "Customer")
though your database table is customer it reads as Customer because annotated class hibernate configures as Customer
so update,
List<Customer> li = session.createQuery("from Customer").list();
I'm newer in java development. I want to add validators to our project. But I had a problem. Please help me!
I add
<dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>

And my DTO:

I have no idea what's wrong. I google,but I can't find something else like this, pls help me. thank you!
According to m4gic's suggestion.I try code a demo:
controller
#RequestMapping(value="/index")
#ResponseBody
public DataResult<User> index(#Valid User request,Errors errors){
User user = new User();
DataResult<User> result = new DataResult<>();
if(errors.hasErrors()){
result.setMsg(errors.getAllErrors().get(0).getDefaultMessage());
}
result.setData(user);
return result;
}
User.java
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#NotBlank(message = "name is null!")
private String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
DataResult.java
public class DataResult<T> implements Serializable {
private static final long serialVersionUID = 1L;
private int code;
private String msg;
private T data;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}
But It works well.NO error;Result:
{
"code": 0,
"msg": "name is null!",
"data": {
"name": null,
"age": 0
}
}
I think what you definitely can do is to try to handle validation errors in different way.
Maybe the problem is that you are trying to handle errors in a controller function having #ResponseBody that would mean that the error should be given back as json. If you would use controlleradvice or custom exception handler, that may help you out.
The other thing you can do is to create a proper spring boot project (after figuring out that using boot 1.4.0.RELEASE will create a project that will contain spring 4.3.2.RELEASE and everything else that is compatible). Then try to reproduce your error in this project (with boot-controlled compatible dependency-set). If there is no error, then you have to compare the two projects dependency tree, because very probably you are using some incompatible jars.
Since you are using Hibernate, check if you have bidirectional mapping. Those can cause infinite recursion. For example if you have parent class A and child class B, and A has list of B`s but B also have reference to its parent A. This will be major problem for serialization. Solution is to either break bidirectional mapping or implement some kind of guard to not populate field of type A in class B.

I am trying to use a User repository in my code, but intellij is giving me the error.
interface is not allowed for non abstract beans
I have the following setup.
#Entity
public class User {
#Id
private long id;
private String firstName;
private String lastName;
private String profileUrl;
private String email;
private String location;
protected User(){};
public User(String first, String last, String profileUrl, String email, String location){
this.firstName = first;
this.lastName = last;
this.profileUrl = profileUrl;
this.email = email;
this.location = location;
}
public User(Person person){
this.firstName = person.getName().getGivenName();
this.lastName = person.getName().getFamilyName();
this.profileUrl = person.getImage().getUrl();
this.email = person.getEmails().get(0).getValue();
this.location = person.getCurrentLocation();
}
}
public interface UserRepository extends CrudRepository<User, Long> {
List<User> findByProfileId(long id);
}
I have tried to annotate this with #Service and #Repository but to no avail.
#Component
public class UserRepositoryImpl {
#Autowired
private UserRepository userRepository;
public void doSomething() {
List<User> byProfileId = userRepository.findByProfileId(100);
}
}

Error occurs in the line of my spring.xml where I am defining my userRepository bean.
Thanks in advance.
#Repository is missing, try adding above the interface of the repo and remove bean declaration that is not allowed in Spring.
I believe you just need to remove this line:
<bean id="userRepository" class="com.planit.persistence.registration.UserRepository"/>
See the SpringData docs here.

}
following two configurations into your spring context file
use spring-mybatis version 1.2.0
Change: Change your sqlSession factory to read your mappers files
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis/sqlmap-config.xml" />
<property name="mapperLocations" value="classpath:mybatis/mappers/*.xml" />
</bean>
Add following entry
<!-- scan for mappers and let them be autowired -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.comcast.triage.persistance" />
</bean>
