@RequestBody

http://localhost:8080/user/login
{
    "username":"jack",
    "passward":null,
    "createTime":null
}

@RequestBody 主要处理json

    @PostMapping("/user/login")
    @WebLog(description = "请求了用户登录接口")
    public User userLogin(@RequestBody User user) {
        logger.info("user login ...");
        return user;
    }

@RequestParm

http://localhost:8080/user/login?token=123
{
    "username":"jack",
    "passward":null,
    "createTime":null
}

@RequestParm主要处理参数，required = false就是用户的请求的参数并没有输入不会报错，如果是true就会报错

     */
    @PostMapping("/user/login")
    @WebLog(description = "请求了用户登录接口")
/*
    public User userLogin(@RequestBody User user) {
        logger.info("user login ...");
        return user;
    }
*/
    public User userLogin(@RequestBody User user,@RequestParam(value = "token",required = false) String token) {
        logger.info("user login ...");
        logger.info("user login token {}",token);
        return user;
    }

当为required =true的时候，http://localhost:8080/user/login输入的返回是

{
    "timestamp": "2019-09-06T09:08:10.747+0000",
    "status": 400,
    "error": "Bad Request",
    "message": "Required String parameter 'token' is not present",
    "path": "/user/login"
}
