在PoolingClientConnectionManager中检查可用的连接 [英] Check available connections in PoolingClientConnectionManager

问题描述

有没有办法(以及如何)知道连接池的状态?就像，正在使用多少个连接，多少个可用，...

Is there a way (and how) to know the status of a connection pool? Like, how many connections are being used, how many are available, ...

我们当前面临的问题是应用程序无法从池中获得连接(ConnectionPoolTimeoutException:等待池中的连接超时)，以便找出导致每次请求新连接时我们都要记录一些池统计信息的原因.

We are currently facing issues where the application cannot get a connection from the pool (ConnectionPoolTimeoutException: Timeout waiting for connection from pool) so to track down the cause we would like to log some pool stats each time a new connection is requested.

我一直在浏览Apache HTTPClient API，但是没有找到获取此信息的方法.
