本文详细介绍了Mina框架中Session的回调函数，包括建立连接、客户端进程关闭、服务端进程关闭、服务端未开启和服务端主动关闭连接等场景下的不同回调事件，如IoHandler的sessionCreated、sessionOpened、sessionClosed、exceptionCaught等。

Mina session回调函数

最近在使用mina，总结一下session相关的回调函数。

1. 场景：建立连接

1.1. 服务端IoAcceptor

IoHandler.sessionCreated

IoHandler.sessionOpened

IoServiceListener.sessionCreated

1.2. 客户端IoConnector

IoServiceListener.serviceActivated

IoHandler.sessionCreated

IoHandler.sessionOpened

IoServiceListener.sessionCreated

2. 场景：客户端进程关闭

2.1. 服务端IoAcceptor

IoHandler.exceptionCaught

java.io.IOException: 远程主机强迫关闭了一个现有的连接。

IoHandler.sessionClosed

IoServiceListener.sessionDestroyed

3. 场景：服务端进程关闭

3.1. 客户端IoConnector

IoHandler.exceptionCaught

IoHandler.sessionClosed

IoServiceListener.sessionDestroyed

IoServiceListener.serviceDeactivated

4. 场景：服务端未开启

java.net.ConnectException: Connection refused: no further information

5. 场景：服务端调用session.closeNow()

5.1. 客户端IoConnector

IoHandler.inputClosed

注：在IoHandler.inputClosed调用session.closeNow()才能触发IoHandler.sessionClosed回调。

5.2. 服务端IoAcceptor

IoHandler.sessionClosed

IoServiceListener.sessionDestroyed
