java - ClassCastException : org. springframework.orm.jpa.EntityManagerHolder 无法转换为 org.springframework.orm.hibernate5.SessionHolder

标签 java hibernate spring-mvc spring-boot dependency-injection

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 个地方调用了 registerNewUserAccount(UserDto userDto) 方法。

  1. 在启动时，我调用此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("aa@bb.cc");
            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 Controller 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 Controller 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;
}
}

我调试过了。命令 userService.test(); 通过了，但是在 registerNewUserAccount(UserDto userDto) 命令抛出以下异常

最佳答案

我将 exclude = HibernateJpaAutoConfiguration.class 属性添加到 @SpringBootApplication 注释中，如 https://stackoverflow.com/a/38637273 所推荐一切正常。但我无法解决问题和解决方案。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的地方不起作用。
