  124.         return ResponseEntity.ok().body(new ResultVO(0,"请求成功",map));
  125.     }
  128. }

备注：一定要加 @CrossOrigin(origins = "*", allowedHeaders = "*")  解决跨域问题。


三、使用 Prism 测试


1、下载 prism

prism 下载地址：http://stoplight.io/platform/prism/

windows下 下载完成后是一个 prism_windows_amd64.exe 文件



2、保存 OpenAPI 代码到文件中

将上面的代码保存为一个 json 或 yaml 文件，比如我这里保存为 swagger.yaml



3、运行之

prism_windows_amd64.exe run --mock --list --cors --spec E:\桌面\swagger.yaml





然后就可以在 swagger 里测试各种请求方式啦

备注：一定要开启跨域(即加--cors)，否则获取不到数据
