如何将以下CURL更改为JAVA中的REST Client？

问题描述

我的卷曲命令是

curl -X POST“ https：// myTestServer / knox / api / v1 / files” -H“ accept：application / json” -H “授权：基本YTM1MjM0ODpQYXNzd29yZEAzNDU =” -H“内容类型：multipart / form-data” -F “ file=@test.pdf; type = application / pdf” -F“ entity = {” name“：” PDF.22427922.02“，” size“： 160135，“ organization”：“ TEST”}“
