先上代码,大家帮忙看下。
服务端:
package Server;
import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.nio.NioServerSocketChannel;
public class HelloServer {
private static final int port = 7878;
public void start() throws InterruptedException {
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workGroup = new NioEventLoopGroup();
try {
ServerBootstrap b = new ServerBootstrap();
b.group(bossGroup, workGroup);
b.channel(NioServerSocketChannel.class);
b.option(ChannelOption.SO_BACKLOG, 1024);
b.childHandler(new SCCHandler());
// 绑定端口
ChannelFuture f = b.bind(port).sync();
// 等待服务端监听端口关闭
f.channel().closeFuture().sync();
} finally {
// 优雅的退出
bossGroup.shutdownGracefully();
workGroup.shutdownGracefully();
}
}
public static void main(String[] args) {
try {
new HelloServer().start();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
客户端测试高并发的DEMO:
package Client;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
import io.netty.bootstrap.Bootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.nio.NioSocketChannel;
public class HelloClient {
public static void main(String[] args) throws Exception {
ScheduledExecutorService scheduledThreadPool = Executors
.newScheduledThreadPool(3000);
for (int i = 0; i < 3000; i++) {
scheduledThreadPool.schedule(new Runnable() {
public void run() {
try {
System.out.println("go");
new HelloClient("192.168.2.88", 7878).start();
} catch (Exception e) {
System.out.println("压力测试失败->" + e.toString());
}
}
}, 200, TimeUnit.MILLISECONDS);
}
System.out.println("压力测试提交完成");
}
private final String host;
private final int port;
public HelloClient(String host, int port) {
this.host = host;
this.port = port;
}
public void start() throws Exception {
System.out.println("链接服务器开始");
EventLoopGroup group = new NioEventLoopGroup();
try {
Bootstrap b = new Bootstrap();
b.group(group);
b.channel(NioSocketChannel.class);
// b.remoteAddress(new InetSocketAddress(host, port));
b.option(ChannelOption.TCP_NODELAY, true);
b.handler(new ClientCCHandler());
// ChannelFuture f = b.connect().sync();
ChannelFuture f = b.connect(host, port);
f.channel().closeFuture().sync();
} finally {
group.shutdownGracefully();
}
}
}
到5000以上就就会出现无法连接的状态了……求解!!
