controller层是这样的
@Controller
@RequestMapping("web_User")
public class UserController {
private static final Logger logger = Logger.getLogger(UserController.class);
@Resource
private UserService userService;
/**
* 获取具体用户信息
* */
@RequestMapping(value = { "getUserById_test" }, method = { RequestMethod.POST })
public @ResponseBody
Map getVideoById(@RequestParam long id) {
User user = userService.finduserById(id);
Map map = new HashMap();
map.put("result", user);
return map;
}
}
applicationcontext是这样的
