我有一个xhtml页面，它接受一些信息并调用addUser方法。当它这样做时，我收到错误：

我猜的主要线索是UserTransaction not allowed for Container managed Transaction beans。我的项目是JTA管理的，我在网上找到的所有教程都使用UserTransaction。我是java ee的新手，所以我不知道如何解决这个问题。

我应该如何重构我的代码（一个例子应该很棒）。我应该切换到项目中的RESOURCE_LOCAL并使用EntityTransaction。这甚至适用于jsf及其容器。如果是的话怎么样？

其余代码如下：

@Named("userService")
@RequestScoped
public class UserService {   

  User usr;    
  @EJB
  private UserDAO usDAO;    

  public void addUser(){
    try {
        if(usDAO == null)
            usDAO = new UserDAOImpl();
        emDAO.addUser(usr);
    } catch (UserException ex) {

    }
}

public void setUsr(User usr) {
    this.usr = usr;
}   

public User getUsr() {
    if(usr == null)
        usr = new User();
    return usr;
}      
}

@Local
public interface UserDAO {...

@Stateless
public class UserDAOImpl implements UserDAO{

    @PersistenceContext
    EntityManager em;

    @Resource
    UserTransaction tx;

    public void addUser(User usr) throws UserException {

    //EntityTransaction tx = em.getTransaction();
    try{
        tx.begin();
        em.persist(usr);
        tx.commit();
    }
    catch(Exception e){
                try {
                    tx.rollback();
                } catch (Exception ex) {

                }
        throw new UserException();
    }

}

答案 0 :(得分：5)

使用JTA时，您无需手动管理事务。也许您正在阅读Java SE或Tomcat目标教程，这些教程确实需要RESOURCE_LOCAL并手动摆弄事务（没有EJB！）。这在真正的Java EE中是不必要的。

在带有JTA的@Stateless EJB内，单个方法调用默认计为单个事务。

所以，这应该做：

@Stateless
public class UserDAOImpl implements UserDAO {

    @PersistenceContext
    EntityManager em;

    public void addUser(User usr) {
        em.persist(usr);
    }

}

这就是全部。 Java EE容器本身将管理事务的启动，提交和回滚。
