Hibernate does not generate tables when #GeneratedValue is set

Hibernate does not generate tables when #GeneratedValue is set - java

I have some code on Spring/Hibernate/Jersey. I want Hibernate to generate my tables. This is my User entity
#Entity
public class User {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private String id;
private String email;
private String nickname;
private String password;
#OneToOne(cascade=CascadeType.ALL)
private PersonalInfo personalInfo;
#OneToOne(fetch=FetchType.LAZY ,cascade=CascadeType.ALL)
private AccountInfo accountInfo;
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 getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public PersonalInfo getPersonalInfo() {
return personalInfo;
}
public void setPersonalInfo(PersonalInfo personalInfo) {
this.personalInfo = personalInfo;
}
public AccountInfo getAccountInfo() {
return accountInfo;
}
public void setAccountInfo(AccountInfo accountInfo) {
this.accountInfo = accountInfo;
}
public User(){
}
}
And this is my configuration:
<beans xmlns="http://www.springframework.org/schema/beans"

It generates the tables when the #GeneratedValue(strategy=GenerationType.IDENTITY) is removed but it does not when I set it.

If you want to use generated value for primary key or something like that try to use Integer in both the table structure and Java.
private String id;
try to make it
private int id;
make sure you have designed the User table similarly(Integer and auto generated ).

I'm newer in java development. I want to add validators to our project. But I had a problem. Please help me!
I add

And my DTO:

public User4BlackListRequest(){}
public String getRealName() {
return realName;
}
public void setRealName(String realName) {

}
public Integer getIsDelete() {
return isDelete;
}
public void setIsDelete(Integer isDelete) {

}
public void setUserType(UserTypeEnum userType) {

public UserTypeEnum getUserType() {
return userType;

controller

if(result.hasErrors()){
String msg = result.getAllErrors().get(0).getDefaultMessage();
logger.info(msg);
}
return DataResult.SuccessData(userService.getList4BlackList(request, pageParam, sortParam));

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.

How to create emdedded H2 DB with spring(transactional) and hibernate in java desktop application?

I am trying to create a project with embedded h2 db, and using spring framework with hibernate. My database will be created in initialize time if not exist. My development platform is intellij.
Problem is that when i run the application

here is my classes and config files.

HibernateException: saveOrUpdate is not valid without active transaction

Perhaps this question has been asked severally but am not able to find a solution to this. I am new to Spring and trying to working on a simple project to integrate Spring with Hibernate 4 using annotations. Whenever i click the user form to save to DB it throws this exception:

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.

I am not getting any sort of error.... in the console.
Updated code..
package your.intermedix.services;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Service;
import your.intermedix.domain.Contact;
import your.intermedix.services.IContact;
#Service
public class ContactSerImpl implements IContact {
private HibernateTemplate hibernateTemplate;
public void setSessionFactory(SessionFactory sessionFactory) {
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
#Transactional
public void saveContact(Contact contact) {
System.out.println("Hello Guru contact");
System.out.println(contact);
hibernateTemplate.saveOrUpdate(contact);
}
public void hello() {
System.out.println("Hello Guru");
}
}
My Service class where i the print statements work

You need a running transaction. Spring transaction management is the way to go if using HibernateTemplate. Read the documentation. It's too long to include in an answer, but here is in short:
you need to define a transaction manager as a spring bean
you need <tx:annotation-driven />
you need to annotate your transactional methods with #Transactional

I don't know the Spring-Hibernate framework, but often when data is not written it menas it is not flushed to the databackend. What gives you
System.err.println(hibernateTemplate.getFlushMode());

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Hibernate does not generate tables when #GeneratedValue is set - java

If you want to use generated value for primary key or something like that try to use Integer in both the table structure and Java. private String id; try to make it private int id; make sure you have designed the User table similarly(Integer and auto generated ).
