源代码public void clientData(HttpServletRequest request, HttpServletResponse response){
InputStream in = request.getInputStream();
String body = null;
body = IOUtils.toString(in);
}

server.xml具有以下配置
connectionTimeout ="20000";maxThread ="150">
有数千个客户端并发访问tomcat服务器
注意:无法重现上述情况，有时会出现此异常
server.xml中达到20秒(connectionTimeout)后发生异常
发现一个问题，问题是由于客户端和服务器之间的带宽。当我们减少客户端和服务器之间的流量(请求数据大小减少)
运行正常
