Apache Mina study notes (4) - Filters

IoFilter is another core part of MINA. It filters all I/O events and requests for IoService and IoHandler, similar to the servlet filter in the web.

In this tutorial, we will develop a IoFilter in practical examples, usually it is easy to implement, but you may need to know some internal details of MINA.

The following are some existing Filters:

You can inherit IoAdapter instead of directly implementing IoFilter. Unless overridden, any received events will be passed through the following filter:

public class MyFilter extends IoFilterAdapter {  
    @Override  
    public void sessionOpened(NextFilter nextFilter, IoSession session) throws Exception {  
        // Some logic here...  
        nextFilter.sessionOpened(session);  
        // Some other logic here...  
    }  
}
