Spring RestController:拒绝具有未知字段的请求

本文介绍了Spring RestController:拒绝具有未知字段的请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有以下端点:

import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*; import static org.springframework.http.MediaType.APPLICATION_JSON_VALUE; import static org.springframework.web.bind.annotation.RequestMethod.POST; @RestController public class TestController { @RequestMapping(value = "/persons", method = POST, consumes = APPLICATION_JSON_VALUE, produces = APPLICATION_JSON_VALUE) public ResponseEntity<Integer> create(@RequestBody Person person) { // create person and return id } }

今天，如果我收到带有这样未知字段的请求:

Today if I received a request with an unknown field like this :

{ "name" : "Pete", "bijsdf" : 51 }

我创建了这个人，而忽略了未知字段.

I create the person and ignore the unknown field.

如何检查是否存在未知字段，然后返回错误的请求?

How can I check that there's an unknown field and then return a bad request ?
