您好，在验证用户表单时遇到Hibernate问题。验证本身是有效的，方法将用户添加到数据库没有验证工作，但结合在一起给了我javax.persistence.RollbackException：提交事务时出错。我找不到任何解决办法。
这是我的域类：
@Entity
public class User {
@Id
@GeneratedValue
private long id ;
@Pattern(regexp= "[a-zA-Z ]+", message="{pattern.user.name.validation}")
private String name;
@Size(min=5, message="{pattern.user.password.validation}")
private String password;
@Pattern(regexp="[a-zA-Z0-9.!#$%&’*+=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:.[a-zA-Z0-9-]+)" , message="{pattern.user.email.validation}")
@UserEmail
private String email;
@Pattern(regexp= "[a-zA-Z0-9./ ]{4,60}", message="{pattern.user.address.validation}")
private String address;
@Pattern(regexp="[0-9-]{7,14}" , message="{pattern.user.tele.validation}")
private String telephone;
@Pattern(regexp="[0-9-/]{8,10}" , message="{pattern.user.birth.validation}")
private String birth;
这是存储库：
@Repository
public class JpaUserRepository implements UserRepository {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("myDB");
public boolean checkEmail(String email) {
EntityManager entityManager = entityManagerFactory.createEntityManager();
javax.persistence.Query query = entityManager.createQuery("select name from User where email=:check");
query.setParameter("check", email);
String test = query.getResultList().toString();
if (test.equalsIgnoreCase("[]")) {
entityManager.close();
return false;
}
else {
entityManager.close();
return true;
}
}
public void createUser(User user) {
EntityManager createManager = entityManagerFactory.createEntityManager();
createManager.getTransaction().begin();
System.out.println(user);
createManager.persist(user);
createManager.getTransaction().commit();
createManager.close();
}
}
这是验证界面：
public class UserEmailValidator implements ConstraintValidator<UserEmail,String>{
@Autowired UserService userservice;
public void initialize(UserEmail constraintAnnotation) {
}
public boolean isValid(String value, ConstraintValidatorContext context) {
if(userservice.checkEmail(value)==false)
{
System.out.println("valid ok");
return true;
}
System.out.println("valid not ok");
return false;
}}
和控制器：
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value = "/signup", method = RequestMethod.GET)
public String signUp(Model model) {
User newUser = new User();
model.addAttribute("newUser", newUser);
return "registration";
}
@RequestMapping(value = "/signup", method = RequestMethod.POST)
public String signUpProcess(@ModelAttribute("newUser") @Valid User newUser,BindingResult result, Model model,
HttpServletRequest request) {
if (result.hasErrors()) {
return "registration";
}
userService.createUser(newUser);
model.addAttribute("name", newUser.getName());
return "accountSuccess";
}}
