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