🗣 Wd提问: websocket服务器 java

🤖 Ai回答:
使用Java实现WebSocket服务器可以借助以下技术：

1、标准API实现（Jakarta WebSocket）
java
import jakarta.websocket.*;
import jakarta.websocket.server.ServerEndpoint;
import java.io.IOException;

@ServerEndpoint(/websocket)
public class MyWebSocketEndpoint {
@OnOpen
public void onOpen(Session session) {
System.out.println(Client connected: + session.getId());
}

@OnMessage
public void onMessage(String message, Session session) {
System.out.println(Received: + message);
try {
session.getBasicRemote().sendText(Server received: + message);
} catch (IOException e) {
e.printStackTrace();
}
}

@OnClose
public void onClose(Session session, CloseReason closeReason) {
System.out.println(Session closed: + session.getId() + Reason: + closeReason.getReasonPhrase());
}
}

2、Spring Boot集成
java
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketHttpHeaders;
import org.springframework.web.socket.client.standard.StandardWebSocketClient;
import org.springframework.web.socket.server.standard.ServletServerContainerFactoryBean;
import org.springframework.context.annotation.Bean;

// 配置类示例
@Bean
public ServletServerContainerFactoryBean createWebSocketContainer() {
return new ServletServerContainerFactoryBean();
}

// 客户端连接示例
public void connectToWebSocket() {
StandardWebSocketClient client = new StandardWebSocketClient();
WebSocketHttpHeaders headers = new WebSocketHttpHeaders();
client.doHandshake(new MyWebSocketHandler(), headers, ws://localhost:8080/websocket);
}

3、Netty实现
java
public class WebSocketServer {
public static void main(String[] args) throws Exception {
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workerGroup = new NioEventLoopGroup();

try {
ServerBootstrap b = new ServerBootstrap();
b.group(bossGroup, workerGroup)
.channel(NioServerSocketChannel.class)
.childHandler(new ChannelInitializer<SocketChannel() {
@Override
public void initChannel(SocketChannel ch) {
ch.pipeline().addLast(
new HttpServerCodec(),
new WebSocketServerProtocolHandler(/websocket),
new TextWebSocketFrameHandler()
);
}
});

ChannelFuture future = b.bind(8080).sync();
future.channel().closeFuture().sync();
} finally {
bossGroup.shutdownGracefully();
workerGroup.shutdownGracefully();
}
}
}

依赖配置（Maven）：
xml
<! Jakarta WebSocket
<dependency
<groupIdjakarta.websocket</groupId
<artifactIdjakarta.websocket-api</artifactId
<version2.0</version
</dependency

<! Spring WebSocket
<dependency
<groupIdorg.springframework</groupId
<artifactIdspring-websocket</artifactId
<version6.0.9</version
</dependency

<! Netty
<dependency
<groupIdio.netty</groupId
<artifactIdnetty-all</artifactId
<version4.1.92.Final</version
</dependency

部署方式：
使用Servlet容器（Tomcat/Jetty）
Spring Boot内嵌服务器
独立Netty服务
Jakarta EE应用服务器

建议根据项目需求选择合适方案：
1、简单实现推荐Jakarta标准API
2、Spring项目优先使用Spring WebSocket
3、高性能场景选择Netty
4、企业级应用可考虑Jakarta EE服务器实现
