這是控制器部分
@Controller

private static final Logger logger = Logger

}
@Autowired
private EmpService service;
@Autowired
private UserService userservice;

return userservice;
}
public void setUserservice(UserService userservice) {
this.userservice = userservice;
}
public EmpService getService() {
return service;
}
public void setService(EmpService service) {
this.service = service;
}
