仅从这个 exception 看，我怀疑是最后一张图 File Upload 里面，MIME 类型应该是 image/png

[mypchas6fans]

说错了，是 image/jpeg。并且参数名称那里应该是“ file ”。
Parameters 这个 tab 里的 3 行参数可能都不需要

[wsds]

@mypchas6fans
改了，报错不一样了
{"timestamp":1526452878375,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"java.lang.RuntimeException: java.io.IOException: Missing initial multi part boundary","path":"/api/intellif/image/upload/true"}

[mypchas6fans]

看看结果树里面请求的内容吧，如果确实没有 boundary，把那个 use multipart/for-data for post 勾掉，然后自己加一个 http header：
名称 Content-Type
值 multipart/form-data; boundary=----WebKitFormBoundarya9MF0hb2gtA3RQ0K

[glacer]

multipart 上传文件
