Cannot resolve method 'create' in 'RequestBody'

[7]

RequestBody body = RequestBody.create(mediaType, JSON.toJSONString(accessTokenDTO));
Request request = new Request.Builder()
.url("https://github.com/login/oauth/access_token")
.post((okhttp3.RequestBody) body)
.build();

create方法报错，如何解决啊？卡在这里了

求解决

有人帮忙解决下嘛

已解决，知悉看了引入的依赖，发现RequestBody引错了

[7]

package com.example.demo.provider;

import com.alibaba.fastjson.JSON;
import com.example.demo.dto.AccessTokenDTO;
import com.example.demo.dto.GitHubUserDTO;
import okhttp3.*;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestBody;

import java.io.IOException;

删掉import org.springframework.web.bind.annotation.RequestBody;

归总：
// import org.springframework.web.bind.annotation.RequestBody;
// 上面这个引入RequestBody是巨坑，https://blog.csdn.net/qy_0626/article/details/107716733
// 别引入错了，所以说自动引入有时候在不熟悉java时，有点难搞
