UserAction中通过@Autowired注入UserServiceImpl无效，得到对象为空
UserAction.java

@Namespace("/") @ParentPackage("struts-default") @Controller public class UserAction extends ActionSupport implements ModelDriven { private User user = new User(); public User getModel() { return this.user; } // ***************************** @Autowired private UserService userService; @Action(value = "userAction_add", results = { @Result(name = "add", location = "/success.jsp") }) public String add() { this.userService.saveUser(user); return "add"; } }

UserServiceImpl.java

@Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Transactional public void saveUser(User user) { this.userDao.save(user); } @Transactional public void updateUser(User user) { this.userDao.update(user); } @Transactional public void deleteUser(User user) { this.userDao.delete(user); } @Transactional(readOnly = true) public User findUserById(Integer id) { return this.userDao.findById(id); } @Transactional(readOnly = true) public List findAllUser() { return this.userDao.findAll(); } }
