在Java中使用Netty监听Socket需要以下步骤:
1. 导入Netty相关依赖包,如:
```xml
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.58.Final</version>
</dependency>
```
2. 创建一个EventLoopGroup对象来处理IO事件,如:
```java
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workerGroup = new NioEventLoopGroup();
```
3. 创建一个ServerBootstrap对象,用于引导服务器启动,如:
```java
ServerBootstrap serverBootstrap = new ServerBootstrap();
serverBootstrap.group(bossGroup, workerGroup)
.channel(NioServerSocketChannel.class)
.childHandler(new ChannelInitializer<SocketChannel>() {
@Override
protected void initChannel(SocketChannel ch) throws Exception {
ChannelPipeline p = ch.pipeline();
// 添加业务处理器
p.addLast(new MyServerHandler());
}
})
.option(ChannelOption.SO_BACKLOG, 128)
.childOption(ChannelOption.SO_KEEPALIVE, true);
```
4. 绑定端口并启动服务器,如:
```java
try {
ChannelFuture f = serverBootstrap.bind(port).sync();
f.channel().closeFuture().sync();
} finally {
workerGroup.shutdownGracefully();
bossGroup.shutdownGracefully();
}
```
其中,MyServerHandler是自定义的业务处理器,可以根据具体需求进行实现。
