最近在学Java的NIO编程，学习过程中编写了一个Demo，特此记录。
- 代码目录结构：
- 代码描述： 使用ThreadPool启动十个客户端线程模拟十个请求，并与服务端保持长连接。每个客户端每隔3秒向服务端发送数据，服务端监听客户端的连接和可读事件，并输出客户端内容。半分钟过后线程池强制中断客户端线程，客户端关闭与服务端的连接，服务端监听客户端的关闭，并将相应事件从selector中取消。
- 客户端代码内容：
NioClient.java 主线程，启动客户端程序。1 package com.vincent.fat.core.nio.client;

Disconnected from the target VM, address: '127.0.0.1:63949', transport: 'socket'
Process finished with exit code 0为了保持长连接，在客户端发送完一次数据以后socketChannel没有关闭，服务端接收完成一次数据以后socketChannel也没有关闭，这样再下次发送数据的时候可以直接发送。但是当客户端线程被中断以后，客户端关闭了sockeChannel，此时服务端没有相应的API判断客户端是否关闭了socket，导致selector在监听事件的时候会无限坚挺到readable（）事件，导致CPU等资源大量浪费，系统崩溃。可以通过如下代码来判断客户端socket是否关闭：
int readBytes = 0;
while ((readBytes=socketChannel.read(byteBuffer))>0) {
//处理数据
content.append(new String(byteBuffer.array(), StandardCharsets.UTF_8));
byteBuffer.clear();
}
//判断客户端断开连接
//当客户端没有断开连接的时候readBytes=0这样保持长连接
//当客户端断开连接的时候readBytes=-1
if (readBytes<0)
{
logger.debug("远程客户端【{}】断开连接.....",socketChannel.getRemoteAddress());
socketChannel.close();
selectionKey.cancel();
}
//处理数据
else {
logger.info("第【{}】次处理数据，收到的内容是： {}",handleDataNo.incrementAndGet(),
content.toString());
}socketChannel.read()此函数返回客户端读取到的字节数，如果大于0 代表有数据读取到，如果=-1代表客户端关闭了连接，此时可以调用 selectionKey.cancel();取消此channel对相应selector的注册。从而避免无限循环的BUG。
