Question

只有当我调用save（）或update（）时才会收到StackOverflow异常，否则它会正常工作。

我的POM文件是

控制器方法：

@RequestMapping(value = API.HOME, 
        method = RequestMethod.GET)
public String home(HttpServletRequest httpRequest, @CurrentUser
        CustomUserDetails currentUserDetail) {
    User user = new User();
    user.setUserId("user1");
    user.setUserName("user1");
    user.setPassword("pass1");
    user.setEmailId("user1@company.com");
    myRepository.getUserService().save(user);
    return new "Success";
}

我有一个JPAConfig.java，我设置了我的dataSource, entityManagerFactory, jpaProperties, jpaVendorAdapter and transactionManager bean和SecurityConfig.java并实现了protected void configure(HttpSecurity http)。

谢谢

很抱歉问题出在我的代码上，即

public class UserRepository implements User {
    @Autowired
    private UserRepository userRepository;

    @Transactional
    public boolean save(User user) {
        User u = userRepository.save(user);
        if(u == null) {
            return false;
        } else {
            return true;
        }
    }
}

无限地调用save（）。这是我在spring 3.1.1中的旧实现，这不适用于spring 4.0.5。

在Spring启动应用程序中的save（）和update（）上获取StackOverflow异常？
