Description

@PostMapping("/loginuser") public String login(@RequestBody ReqLogin reqLogin) { //return JSON.toJSONString(FakeDataUtils.loginResponseData()); return "loginuser," + DateUtil.generateTimestamp(DateUtil.YYYY_M_MDD_HH_MM_SS_SSS2); }

Postman发起请求时，能走到如上的return语句，但是andserver后续流程报空指针，debug发现的。不能贴图，我手动输入一下报错的detailMessage: "Attempt to invoke interface method 'long com.yanzhenjie.andserver.http.ResponseBody.contentLength()' on a null onject reference" 如有需要请加我微信:qq827554583

Contributor guide

Research direction
Trace the request handling pipeline from the controller method returning a String to the response building. The NullPointerException indicates ResponseBody is null, so examine how Content Length is determined and where the ResponseBody is assigned.
