read time out - Githubissues

版本号：2.1.2

部署xxl-job-admin到docker容器中，连接容器中的mysql都正常，现在jobHandler控制台能看到打印信息，表明我的JobHandler已经正确的执行了，可是频繁出现下面的错误：

java.net.SocketTimeoutException: Read timed out at java.base/java.net.SocketInputStream.socketRead0(Native Method) at java.base/java.net.SocketInputStream.socketRead(SocketInputStream.java:115) at java.base/java.net.SocketInputStream.read(SocketInputStream.java:168) at java.base/java.net.SocketInputStream.read(SocketInputStream.java:140) at java.base/java.io.BufferedInputStream.fill(BufferedInputStream.java:252) at java.base/java.io.BufferedInputStream.read1(BufferedInputStream.java:292) at java.base/java.io.BufferedInputStream.read(BufferedInputStream.java:351) at java.base/sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:746) at java.base/sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:689) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1610) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1515) at java.base/java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:527) at com.xxl.job.core.util.XxlJobRemotingUtil.postBody(XxlJobRemotingUtil.java:112) at com.xxl.job.core.biz.client.AdminBizClient.callback(AdminBizClient.java:36) at com.xxl.job.core.thread.TriggerCallbackThread.doCallback(TriggerCallbackThread.java:166) at com.xxl.job.core.thread.TriggerCallbackThread.access$200(TriggerCallbackThread.java:24) at com.xxl.job.core.thread.TriggerCallbackThread$1.run(TriggerCallbackThread.java:74) at java.base/java.lang.Thread.run(Thread.java:834)

这是job-admin与执行器回调，返回值含有中文乱码的问题。解决方案：将XxlJobRemotingUtil 此类（在60行左右）代码： dataOutputStream.writeBytes(requestBody); 改为： dataOutputStream.write(requestBody.getBytes(java.nio.charset.StandardCharsets.UTF_8));

参照github 提交节点：6a0ab3437fc102f9f715bd8b03e33b3059dd5810 或git网址：https://github.com/xuxueli/xxl-job/commit/6a0ab3437fc102f9f715bd8b03e33b3059dd5810

@6haining

我的jar包目前是2.1.2最新的，而且XxlJobRemotingUtil 类的源码查看已经是dataOutputStream.write(requestBody.getBytes(java.nio.charset.StandardCharsets.UTF_8));但是还是有错误。

connection.setRequestMethod("POST"); connection.setDoOutput(true); connection.setDoInput(true); connection.setUseCaches(false); connection.setReadTimeout(timeout * 1000); connection.setConnectTimeout(3000); connection.setRequestProperty("connection", "Keep-Alive"); connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8"); connection.setRequestProperty("Accept-Charset", "application/json;charset=UTF-8"); if (accessToken != null && accessToken.trim().length() > 0) { connection.setRequestProperty(XXL_RPC_ACCESS_TOKEN, accessToken); }

connection.connect(); String requestBody = BasicJson.toJson(requestObj); DataOutputStream dataOutputStream = new DataOutputStream(connection.getOutputStream()); dataOutputStream.write(requestBody.getBytes("UTF-8")); dataOutputStream.flush(); dataOutputStream.close();

int statusCode = connection.getResponseCode();

我的代码追到了最后一行，貌似是connection.readtimeout设置时间太短了。

在类AdminBizClient中，调用的超时时间是写死的。这个3的超时时间没有办法修改吗？

@Override public ReturnT callback(List callbackParamList) { return XxlJobRemotingUtil.postBody(addressUrl+"api/callback", accessToken, callbackParamList,3); }

@Override public ReturnT registry(RegistryParam registryParam) { return XxlJobRemotingUtil.postBody(addressUrl + "api/registry", accessToken, registryParam, 3); }

@Override public ReturnT registryRemove(RegistryParam registryParam) { return XxlJobRemotingUtil.postBody(addressUrl + "api/registryRemove", accessToken, registryParam, 3); }

可以设置成30秒，长一点。或者写到配置文件里，在AdminBizClient类加上 @Component + @Value("xxl.job.client.http.timeout")注入值

超时设置为30秒有点长吧

lwgo2050 commented 2 years ago

为什么3秒还处理不完呢，潮湿时间放的太大也不好啊

stefanxfy commented 2 years ago

我这在生产环境也时常出现心跳超时或者调用超时
