SimpleHttpConnectionManager使用不正确（simple connected）
SimpleHttpConnectionManager使用不正确。确保始终调用HttpMethod.releaseConnection（），并且一次只有一个线程和/或方法正在使用此连接管理器。
是否有人知道为什么会出现此错误，并导致我要下载的文件失败或失败，然后重试或下载未完成的文件
谢谢 ！
答案1
小编典典确保不使用SimpleHttpConnectionManager创建和使用来自多个线程的连接。简单的连接管理器不是为它设计的-
它总是返回相同的连接，这不是线程安全的。
在多线程环境中，请使用使用连接池的其他管理器。请参见MultiThreadedHttpConnectionManager。

apache HttpClient API中的setConnectionTimeout，setSoTimeout和“ http.connection- manager.timeout”之间有什么区别
两者之间有什么区别（标记为评论）：
MultiThreadedHttpConnectionManager connManag = new MultiThreadedHttpConnectionManager();
HttpConnectionManagerParams managParams = connManag.getParams();
managParams.setConnectionTimeout(connectiontimeout); // 1
managParams.setSoTimeout(sotimeout); //2
HttpMethodBase baseMethod = null;
try {
HttpClient client = new HttpClient(connManag);
client.getParams().setParameter("http.connection-manager.timeout",poolTimeout); //3
baseMethod = new GetMethod(…);
int statusCode = client.executeMethod(…);
…
}
catch (ConnectTimeoutException cte ){
//Took too long to connect to remote host
}
catch (SocketTimeoutException ste){
//Remote host didn’t respond in time
}
catch (Exception se){
//Some other error occurred
}
finally {
if (baseMethod != null)
baseMethod.releaseConnection();
}
1. setConnectionTimeout -如果它确定在建立连接之前的超时。
2. setSoTimeout -如果确定两个连续数据包之间的不活动时间段或时间差，
那么下面的一个是做什么的：
3. "http.connection-manager.timeout"
Apache PoolingHttpClientConnectionManager引发非法状态异常
这是我的用法-
private static final PoolingHttpClientConnectionManager connPool;static { connPool = new PoolingHttpClientConnectionManager(); // Increase max total connection to 200 connPool.setMaxTotal(200);//configurable through app.properties // Increase default max connection per route to 50 connPool.setDefaultMaxPerRoute(20);//configurable through app.properties}CloseableHttpClient httpClient = HttpClients.custom() .setConnectionManager(connPool) .build();另外，我在http GET周围放置了一个finally块-
finally { try { httpClient.close(); } catch (IOException e) { LOGGER.error(e.getMessage()); } }这是我的堆栈跟踪-
java.lang.IllegalStateException: Connection pool shut down at org.apache.http.util.Asserts.check(Asserts.java:34) at org.apache.http.pool.AbstractConnPool.lease(AbstractConnPool.java:169) at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.requestConnection(PoolingHttpClientConnectionManager.java:217) at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:157) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:194) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:85) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:108) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:186) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:106) at com.A.B.C.CustomHttpClient.doGETAndValidate(CustomHttpClient.java:44) at com.A.B.C.SiteMonitorTask.monitorAndUpdateEndPoints(SiteMonitorTask.java:48) at com.A.B.C.SiteMonitorTask.run(SiteMonitorTask.java:37) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744)我正在使用Quartz计划监视Http端点的工作。这是我的连接池配置
totalMaxHttpConn=200maxHttpConnPerRoute=20Maven依赖..工件版本
httpclient 4.3.1httpcore 4.3.1编辑 -好吧，通过不关闭finally块中的CloseableHttpClient，问题解决了。有人能说出为什么这样吗？
如果关闭客户端，为什么连接池会关闭？
是上面的closeablehttpclient是池的句柄，而不是单个conn
答案1
小编典典此行为是由于HC 4.3中的错误所致。它已在HC
4.4a1中修复。从4.4版本开始，CloseableHttpClient#close仅在客户端独占时才应自动关闭连接池
