HttpClient_error_Too many open files_如何正确关闭连接和流

Error：

java.io.FileNotFoundException: /usr/local/app/xxx.jpg (Too many open files)

症状分析：

经过检查，读写文件的流都已经正确关闭了，还是报告打开文件数过多

应该就是httpClient的问题了

解决：

官方文档HttpClient的API中：

     // When HttpClient instance is no longer needed,     // shut down the connection manager to ensure     // immediate deallocation of all system resources     httpclient.getConnectionManager().shutdown();

另外，如果多个线程使用一个httpClient，注意releaseConnection

public?void?releaseConnection()

A convenience method to simplify migration from HttpClient 3.1 API. This method is equivalent to?reset().

public?void?reset()

Resets internal state of the request making it reusable.?参考：?HttpClient容易忽视的细节——连接关闭?http://www.iteye.com/topic/234759http://www.2cto.com/kf/201109/103561.html?===+===
