//这个类中一般有exceptionCaught, messageReceived 和 sessionIdle这几个方法。
// exceptionCaught 应该总是在handler 中定义，来处理一些异常情况，否则异常信息将无法捕捉。
//exceptionCaught 方法简单地打印了错误的堆栈跟踪和关闭会话。对于大多数程序，这将是标准的做法，除非处理程序可以从异常状态中恢复。
//messageReceived 方法来处理从客户端接收到的数据，这里是将当前时间返回给客户端，当收到quit时，会话将被关闭，也会返回一个当前时间给客户端。
// 根据所使用的协议编解码器，object 这个参数传递的类型有所不同，以及返回的数据时的session.write(Object) 也不同。
// 如果不指定协议的编解码器，你将收到一个类型为IoBuffer 的对象，返回的数据也要求是IoBuffer。
//sessionIdle 方法将定时调用一次会话，保持空闲状态。通过调用acceptor.getSessionConfig().setIdleTime( IdleStatus.BOTH_IDLE, 10 );来设定时间间隔。
