javax.validation.ConstraintViolationException:preUpdate验证违反了Bean验证约束 [英] javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated on preUpdate validation

问题描述

当我尝试使用JPA 2.0，SpringMvc 3.0以多对多关系插入新元素时，出现了令人讨厌的错误消息.

I'm having an annoying error message while trying to insert new element in a many to many relationship using JPA 2.0, SpringMvc 3.0.

我有一张桌子，上面有国家，另一张桌子上有人".一个人可以链接到许多州，一个州可以链接到许多人. 在这种情况下，我有一个listOfStates，然后是一个人，我想将这些元素插入我的多对多关系中.

I have a table with States and another one with Persons. A person can be linked to many states and a state to many persons. In this particular case, I have a listOfStates and then a person and I would like to insert those elements in my many to many relationships.

多对多关系(在表STATE中)

    //bi-directional many-to-many association to Appointment
    @ManyToMany(cascade=CascadeType.ALL)
    @JoinTable(
name="PERSON_STATE"
, joinColumns={
    @JoinColumn(name="PERSON_ID", nullable=false)
    }
, inverseJoinColumns={
    @JoinColumn(name="CODE_STATE", nullable=false)
    }
)

我从控制器调用的DAO代码

try{    
    getEntityManager().getTransaction().begin();            
    getEntityManager().persist(myPerson);                       

    IStateDAO stateDAO = new StateDAO();

    for (int i=0; i<listOfStates.length; i++){
        State myState = stateDAO.findState(listOfStates[i]);
        if (myState != null){                   
            myState.getPersons().add(myPerson);
            getEntityManager().persist(myState);
        }
    }

    getEntityManager().getTransaction().commit();           
    getEntityManager().close();         

} catch (RuntimeException re) {
    getEntityManager().close();
    throw re;           
}

有趣的是，当我不从网页中插入数据时，此代码可以正常工作.我在这里做错了什么?数据库中已经有一些人和州了.

The funny thing is that this code is working fine when I'm not inserting data from a web page. What i am doing wrong here? I already have some persons and states in the DB.

完整堆栈错误消息:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'preUpdate'.

任何指针将不胜感激.预先谢谢大家.

Any pointer would be really appreciated. Thanks in advance you all.

推荐答案

哇！知道了！我不得不将persistence.xml中的 validation-mode 从自动更改为 NONE ，这基本上告诉应用程序根本不使用Bean验证.错误消息消失了，我的DAO正常工作了.

wow! got it! I had to change the validation-mode in my persistence.xml from Auto to NONE which basically tells the app not to used the bean validation at all. Error messages are gone and my DAO works well.
