我有一个用Java编写的服务器,在Tomcat下运行Spring MVC(Spring BOOT)。我们注意到一些客户机正在发送一个POST请求,该请求具有一个内容长度头,但没有实体体。当这个请求进入时,请求挂起20秒,然后一个响应(400)从服务器返回。

servlet如下所示:
@RequestMapping(路径=“/event/{apikey}/{anonymousId}”,方法=RequestMethod.POST,products=”应用程序/json“)
公共void clickRawPost(
@路径变量字符串apikey,
@RequestBody(required=false)字符串后置内容,
HttpServletResponse响应)
抛出IOException{
repro命令如下:
$时间卷曲-s
http://localhost:8080/event/test/foo
-H'内容类型:
应用程序/json'-H'内容长度:100'-X POST-v
这个命令20秒后就失效了。
我原以为它会很快失败,因为请求中没有实体实体。
