Spring MVC 对 RESTful 的支持

　　先上代码：

@Controller
@RequestMapping("/users")
public class UserController {
    
    @Autowired
    private UserDao userDao;
    
    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    @ResponseBody
    public Result deleteUser(@PathVariable("id") Integer id) {
        
        User user = userDao.get(User.class, id);
        if (user == null) {
            Result result = new Result();
            result.setResult(Result.ERROR);
            result.setMsg("删除失败，失败原因：不存在该用户。");
            return result;
        }
        userDao.delete(User.class, id);
        Result result = new Result();
        result.setResult(Result.SUCCESS);
        result.setMsg("成功删除。");
        return result;
    }
}

　　以上。
