org.apache.http.impl.client.HttpClientBuilder.build() L1128 // Add request retry executor, if not disabled if (!automaticRetriesDisabled) { HttpRequestRetryHandler retryHandlerCopy = this.retryHandler; if (retryHandlerCopy == null) { retryHandlerCopy = DefaultHttpRequestRetryHandler.INSTANCE; } execChain = new RetryExec(execChain,...

默认 ```JAVA InterruptedIOException.class, UnknownHostException.class, ConnectException.class, SSLException.class ``` 4个不重试 而 SocketTimeoutException 正好属于 InterruptedIOException

dingtalk 是post 请求 //--------------------------------------------------------------- HttpRequest httpRequest = new HttpRequest(BOT_WEBHOOK_URL, POST); https://blog.csdn.net/shope9/article/details/124047321 默认 不是幂等的请求不重试

HttpClient默认是有重试机制的，其重试策略是： 1.只有发生IOExecetion时才会发生重试 2.InterruptedIOException、UnknownHostException、ConnectException、SSLException，发生这4中异常不重试 3.get方法可以重试3次，post方法在socket对应的输出流没有被write并flush成功时可以重试3次。 4.读/写超时不进行重试 5.socket传输中被重置或关闭会进行重试 6.以及一些其他的IOException，暂时分析不出来。

StandardHttpRequestRetryHandler According to RFC-2616 section 9.1.2 the idempotent HTTP methods are: GET, HEAD, PUT, DELETE, OPTIONS, and TRACE 都会去重试
