spring请求异常，Content type ‘application/x-www-form-urlencoded;charset=UTF-8’ not supported for @RequestBody MultiValueMap
Content type ‘application/x-www-form-urlencoded;charset=UTF-8’
not supported for @RequestBody MultiValueMap

因为在spring的方法中包含requestbody ，前台船体过来的是json格式的，这里不认识

The problem is that when we use application/x-www-form-urlencoded, Spring doesn’t understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

问题是，当我们使用应用程序/x-www-urlen编码时，Spring并不理解它是一个请求体。因此，如果我们想要使用这个，我们必须删除@requestbody注释。
