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.
