【问题描述】：

我尝试创建简单的用户登录和注册页面。但我无法使用服务方法创建用户。 我有一个创建新用户的服务。

@Service
public class LocalUserDetailsService implements UserService 

//...

@Transactional
@Override
public User registerNewUserAccount(UserDto userDto) throws EmailExistsException 
    System.out.println("registerNewUserAccount called");
    if (emailExist(userDto.getEmail())) 
        throw new EmailExistsException(
                "There is an account with that email adress: "
                + userDto.getEmail());
    

    return createUser(userDto);


private User createUser(UserDto userDto) 
    User user = new User();
    user.setEmail(userDto.getEmail());
    user.setPassword(passwordEncoder.encode(userDto.getPassword()));
    user.setEnabled(userDto.isEnabled());
    Set<Role> roles = new LinkedHashSet<>();

    userDto.getRoles().forEach((roleDto) -> 
        roles.add(roleDao.getOrInsert(roleDto.getName()));
    );

    user.setRoles(roles);

    return userDao.insert(user);

我在 2 个地方调用 registerNewUserAccount(UserDto userDto) 方法。

在启动时，我调用这个方法来创建初始用户。

@Component
public class DatabaseFillerOnStartup implements ApplicationListener<ContextRefreshedEvent> 

    @Autowired
    private UserService userService;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) 
        System.out.println("DatabaseFillerOnStartup ###################");
        createInitialUsers();
    

    private void createInitialUsers() 
        try 
            UserDto user = new UserDto();
            user.setEmail("[e-mail]");
            user.setPassword("123456");
            user.setEnabled(true);
            List<RoleDto> roles = new ArrayList<>();
            roles.add(new RoleDto(Roles.ADMIN));
            roles.add(new RoleDto(Roles.USER));
            user.setRoles(roles);
            userService.registerNewUserAccount(user);
         catch (EmailExistsException ex) 
            Logger.getLogger(DatabaseFillerOnStartup.class.getName())
                    .log(Level.SEVERE, null, ex);
        
    

然后一切正常。但是当我从控制器调用此方法以使用注册表单创建新用户时，registerNewUserAccount(UserDto userDto) 方法不起作用。我从控制器中调用它，如下所示：

@Controller
public class UserController 

@Autowired
private UserService userService;

@RequestMapping(value = "/user/registration", method = RequestMethod.POST)
public ModelAndView registerUserAccount(
        @ModelAttribute("userDto") @Valid UserDto userDto,
        BindingResult result, WebRequest request, Errors errors) 
    User registered = new User();
    if (!result.hasErrors()) 
        registered = createUserAccount(userDto, result);
    
    if (registered == null) 
        result.rejectValue("email", "message.regError");
    
    if (result.hasErrors()) 
        return new ModelAndView("registration", "user", userDto);
     else 
        return new ModelAndView("successRegister", "user", userDto);
    


private User createUserAccount(UserDto userDto, BindingResult result) 
    User registered;
    try 
        userService.test();//Just for testing if service class Autowired correctly.
        registered = userService.registerNewUserAccount(userDto);
     catch (EmailExistsException e) 
        return null;
    
    return registered;

我调试了它。命令userService.test();通过了，但是在registerNewUserAccount(UserDto userDto)命令抛出如下异常

【参考方案1】：

我按照https://***.com/a/38637273 的建议将exclude = HibernateJpaAutoConfiguration.class 属性添加到@SpringBootApplication 注释，并且一切正常。但我不能将问题和解决方案联系起来。而且我不知道为什么registerNewUserAccount(UserDto userDto) 方法在一个地方有效而在不同地方无效。

【讨论】：

我也遇到过同样的问题。解决方案也适用于我。我也无法理解它。谢谢。

谢谢！这有效，但不太明白这个错误的原因。

谢谢！这个解决方案也对我有用。我的推断是，这与由于 HibernateJpaAutoConfiguration 完成的自动配置和其余设置（例如 XML 或 Java 配置）完成的 Hibernate 配置而发生的一些冲突有关。所以，一旦我们要求 Spring 忽略 HibernateJpaAutoConfiguration，一切都变得很糟糕，因为不再有冲突了。

但是设置 spring.jpa.open-in-view=false 也解决了我的问题
