2、错误原因

public interface UserDao { public List< User> findAll(); }@Repository public class UserDaoImpl implements UserDao { @Override public List< User> findAll() { return null; } }public interface UserService { public List< User> findAll(); }public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public List< User> findAll() { return userDao.findAll(); } }@Controller @RequestMapping("/user") public class UserController { @Autowired private UserService userService; @RequestMapping(value = "https://www.songbingjia.com/android/findAll") public void findAll() { userService.findAll(); } }

导致这个错误的原因是Service实现缺少@Service

3、解决办法

public interface UserDao { public List< User> findAll(); }@Repository public class UserDaoImpl implements UserDao { @Override public List< User> findAll() { return null; } }public interface UserService { public List< User> findAll(); }@Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public List< User> findAll() { return userDao.findAll(); } }@Controller @RequestMapping("/user") public class UserController { @Autowired private UserService userService; @RequestMapping(value = "https://www.songbingjia.com/android/findAll") public void findAll() { userService.findAll(); } }
