Mat*_*att 0 java jpa transactions exception
我有一个@Transactional服务在oracle DB中执行持久化操作.如果我运行坚持打破一个唯一的违规,我得到预期的rollbackException:ConstraintException.
问题是任何后续请求(即使没有违反唯一约束)持久化都会引发相同的异常.
似乎JPA没有清除持久化其事务管理器的对象？我甚至关闭？我需要一点解释.
回购:
@Repository
public class UserRepository {
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager em;
public User findUserById(long id){
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<User> query = builder.createQuery(User.class);
Root<User> root = query.from(User.class);
Predicate whereClause = builder.equal(root.get(User_.userId), id);
return em.createQuery(query.where(whereClause)).getSingleResult();
}
public User findUserByCredentials(String credentials){
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<User> query = builder.createQuery(User.class);
Root<User> root = query.from(User.class);
Predicate whereClause = builder.equal(root.get(User_.credentials), credentials);
return em.createQuery(query.where(whereClause)).getSingleResult();
}
public void registerUser(User user){
em.persist(user);
}
}
ServiceImpl:
@Transactional(readOnly=true)
@Service("userService")
public class UserServiceImpl implements UserService {
@Resource
private UserRepository userRepository;
public void setUserRepository(UserRepository userRepository) {
this.userRepository = userRepository;
}
public User findUserById(long id) {
return userRepository.findUserById(id);
}
public User findUserByCredentials(String credentials){
return userRepository.findUserByCredentials(credentials);
}
@Transactional(readOnly=false)
public void registerUser(User user){
userRepository.registerUser(user);
}
}
端点错误抛出:
@PayloadRoot(localPart="RegisterUserRequest", namespace = "http://www.missingwire.com/schemas/User")
public RegisterUserResponseDocument registerUser(RegisterUserRequestDocument requestDoc){
RegisterUserRequest request = requestDoc.getRegisterUserRequest();
User user = new User();
user.setCredentials(request.getCredentials());
user.setPassword(request.getPassword());
user.setHonorRating(BigDecimal.valueOf(STARTING_USER_HONOR_RATING));
user.setAccountActive(true);
user.setDateCreated(new Date());
user.setVerified(false);
UserProfile userProfile = new UserProfile();
userProfile.setEmailAddress(request.getEmail());
userProfile.setFirstName(request.getFirstName());
userProfile.setLastName(request.getLastName());
userProfile.setDateCreated(new Date());
userProfile.setUser(user);
user.setUserProfile(userProfile);
**userService.registerUser(user);** //HERE IS THE EXCEPTION THROW
RegisterUserResponseDocument responseDoc = RegisterUserResponseDocument.Factory.newInstance();
RegisterUserResponse response = responseDoc.addNewRegisterUserResponse();
UserType userType = response.addNewUser();
userType.setAccountActive(user.getAccountActive());
userType.setCredentials(user.getCredentials());
userType.setDateCreated(DateConverter.convertDateToXML(user.getDateCreated()));
userType.setUserId(user.getUserId());
userType.setVerified(user.getVerified());
return responseDoc;
}

您正在为扩展持久性上下文注入实体管理器.这意味着持久化上下文的生命周期与事务的生命周期无关:它会一直保持打开状态,直到您明确地关闭它为止.
由于您遇到RollbackException,持久化上下文处于脏的,不一致的状态,您唯一能做的就是立即关闭它.
如果持久性上下文是事务性上下文,则会自动关闭.但是,由于您使用的是扩展上下文,因此您可以明确地将其关闭.
请务必阅读并理解Spring文档的以下部分:
@PersistenceContext注释具有可选的属性类型,默认为PersistenceContextType.TRANSACTION.此默认值是接收共享EntityManager代理所需的内容.替代方案PersistenceContextType.EXTENDED是一个完全不同的事情:这会产生一个所谓的扩展EntityManager,它不是线程安全的,因此不能在并发访问的组件中使用,例如Spring管理的单例bean.扩展的EntityManagers仅应用于有状态组件,例如驻留在会话中,EntityManager的生命周期不依赖于当前事务,而是完全取决于应用程序.
