How to deal with error applying BeanValidation relational constraints?

Question

I've got some problems with making oneToMany relation in Spring + Hibernate 4.1 application This is my entities classes. Every USER_ROLE record has FK to USER record. I can't find anything useful on the Internet.

@Entity
@Table( name = "USERS" )
public class User {

     long id;
     String login;
     String password;
     String name;
     String surname;
     GregorianCalendar birthDate;
     String email;
     GregorianCalendar joinDate;
     String randomKey;
     List<UserRole> userRoles = new ArrayList<UserRole>();

    public User(){ } //JavaBean Hibernate requirement

    @Id
    @GeneratedValue(generator="increment")
    @GenericGenerator(name="increment", strategy = "increment")
    @Column(name="USER_ID", unique=true, nullable=false)
    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }
...

    @OneToMany(mappedBy = "user", fetch = FetchType.LAZY)
    public List<UserRole> getUserRoles() {
        return userRoles;
    }

    public void setAccountRole(List<UserRole> aUserRoles) {
        for (UserRole role : aUserRoles) {
            this.addUserRole(role);
        }
    }

    public void addUserRole(UserRole aRole) {
        if (!this.userRoles.contains(aRole)) {
            aRole.setUser(this);
            this.userRoles.add(aRole);
        }
    }
}


@Entity
@Table(name = "USER_ROLE")
public class UserRole {

    Integer roleId;
    String role;
    User user;

    public UserRole() { }

//  public UserRole(String role) {
//      this.setRole(role);
//  }

    @Id
    @GeneratedValue(generator="increment")
    @GenericGenerator(name="increment", strategy = "increment")
    @Column(name = "ROLE_ID", unique = true, nullable = false)
    public Integer getRoleId() {
        return roleId;
    }

    public void setRoleId(Integer roleId) {
        this.roleId = roleId;
    }

    @Basic
    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "USER_ID", nullable = false)
    public User getUser() {
        return user;
    }

    public void setUser(User aUser) {
        this.user = aUser;
    }
}

And this is first exception in my stack trace:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: pl.rafalo235.encyklopedia.model.dao.UserDAO pl.rafalo235.encyklopedia.controllers.HomeController.userDAO; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDAO': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.orm.hibernate4.LocalSessionFactoryBean pl.rafalo235.encyklopedia.model.dao.UserDAO.sessionFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/encyklopediaDispatcherServlet-servlet.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Error applying BeanValidation relational constraints

Answer 1

I'm not using Spring and I'm using hibernate 4.1.8 and works adding to my hibernate.cfg.xml:

<property name="javax.persistence.validation.mode">none</property>

Answer 2

Try add to hibernate config in Spring validation.mode - none:

<bean id="sessionFactory"
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <props>
            ....
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

Answer 3

Using JPA and Hibernate works for me adding to persistence.xml:

<property name="javax.persistence.validation.mode" value="none"/>
