REST接口并发稍微高点就报java.net.SocketException: Unexpected end of file from server

Question

各位大神，在开发REST接口后，做压力测试时调用接口，并发稍微高一些就出现以下错误：10:01:44,801 ERROR [TechServiceProxy] Call Service:SYSCONFIG error! And exception:java.net.SocketException: Unexpected end of file from server

看了服务器的ulimit 及iptables都没有问题，求大神给个方向。并发server

10:01:44,801 ERROR [TechServiceProxy] Call Service:SYSCONFIG error! And exception:java.net.SocketException: Unexpected end of file from serverSYSCONFIG 是个什么service？Unexpected end of file from server 意外的结束了？HttpClient.java: 774  使用的httpClient发送的请求？ 自己写的？

客户端用HttpURLConnection写的：URL url = new URL(serviceURL);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
setRequestHeader(httpConn, method, headerParams);
httpConn.setDoOutput(true);
httpConn.setUseCaches(false);
httpConn.setRequestProperty("Cache-Control","no-cache"); 
httpConn.setConnectTimeout(CONNECTION_TIMEOUT);
httpConn.setReadTimeout(CONNECTION_TIMEOUT);
if (accept == null) {
accept = "application/json";
}
httpConn.setRequestProperty("Accept", accept);
if (body != null && !body.equals("")) {
DataOutputStream dos = new DataOutputStream(
httpConn.getOutputStream());
dos.writeBytes(body);
dos.flush();
dos.close();
} else {
httpConn.connect();
}两台都是linux机器没有装360

50并发就这样了啊？那别费劲了。Node.js, 轻松上2000。用Go 随便写个Server也是2000以上。Java就加服务器吧

dos.close();
} else {
httpConn.connect();
}两台都是linux机器没有装360你这代码都不写完整的 httpConn 不接手服务器的响应，也不关掉。。用
httpConn.disconnect()

}是完整的，我没有贴全，额 我不会nodejs 哎 痛苦啊

Answer 6

跑了一下，访问静态页面，很快，不知道是不是你的服务有什么问题。或者你把代码贴全吧。 直接copy你的代码编译不过。
