## 什么是Restfull风格? ##

简单点说就是访问后台时的请求路径与请求的方式有所不同.  
传统的请求路径如:[http://127.0.0.1:8080/user/getUser.do?id=1][http_127.0.0.1_8080_user_getUser.do_id_1]  
Restfull风格的请求路径为:[http://127.0.0.1:8080/user/1][http_127.0.0.1_8080_user_1]

## 操作步骤 ##

将web.xml中

### Controller中的写法 ###

//restful风格增删改查
    
    //新增
    @RequestMapping(value = "user",method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
    @ResponseBody
    public String addUser(User user){
        return "新增用户-" + user;
    }
    
    //修改
    @RequestMapping(value = "user",method = RequestMethod.PUT, produces = "application/json;charset=UTF-8")
    @ResponseBody
    public String editUser(User user){
        return "修改用户-" + user;
    }
    
    //删除
    @RequestMapping(value = "user",method = RequestMethod.DELETE, produces = "application/json;charset=UTF-8")
    @ResponseBody
    public String deleteById(Integer id){
        return "删除用户ID-" + id;
    }
    
    //根据id查询
    @RequestMapping(value = "user/{id}",method = RequestMethod.GET, produces = "application/json;charset=UTF-8")
    @ResponseBody
    public String getUserById(@PathVariable("id") Integer id){
        System.out.println(id);
        return "根据主键查询-" + id;
    }
    
    //条件查询
    @RequestMapping(value = "user",method = RequestMethod.GET, produces = "application/json;charset=UTF-8")
    @ResponseBody
    public String queryUser(User user){
        return "条件查询-" + user;
    }

注意:虽然每个请求的路径都一样,但是请求方式都不同,查询操作一般为GET请求,新增操作一般为POST请求,修改操作一般为PUT请求,删除操作一般为DELETE请求
