springboot如何整合socket.io

Spring Boot 可以通过使用 Spring Websocket 模块来整合 Socket.IO。具体步骤如下:
1. 添加依赖
在 pom.xml 文件中添加以下依赖:
```
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
<groupId>com.corundumstudio.socketio</groupId>
<artifactId>netty-socketio</artifactId>
<version>1.7.16</version>
</dependency>
```
2. 配置 Socket.IO
在 Spring Boot 的配置文件中添加以下配置:
```
server:
port: 8080
socketio:
port: 9092
```
3. 创建 Socket.IO 服务器
在 Spring Boot 应用程序中创建 Socket.IO 服务器:
```
@Configuration
@EnableWebSocket
public class SocketConfig implements WebSocketConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
SocketIOServer server = new SocketIOServer(configuration());
registry.addHandler(new SocketIOHandler(server), "/socket.io").setAllowedOrigins("*");
}
@Bean
public Configuration configuration() {
Configuration config = new Configuration();
config.setHostname("localhost");
config.setPort(9092);
return config;
}
}
```
4. 创建 Socket.IO 处理程序
创建一个 Socket.IO 处理程序来处理客户端的连接和消息:
```
public class SocketIOHandler extends SocketIOServer {
public SocketIOHandler(Configuration configuration) {
super(configuration);
addListeners();
}
private void addListeners() {
addConnectListener(client -> {
System.out.println("Client connected: " + client.getSessionId());
});
addDisconnectListener(client -> {
System.out.println("Client disconnected: " + client.getSessionId());
});
addEventListener("message", String.class, (client, data, ackSender) -> {
System.out.println("Received message: " + data);
broadcast("message", data);
});
}
}
```
5. 创建客户端
创建一个 Socket.IO 客户端来连接到服务器并发送消息:
```
var socket = io.connect('http://localhost:9092');
socket.on('connect', function() {
console.log('Connected to server');
});
socket.on('message', function(data) {
console.log('Received message: ' + data);
});
socket.emit('message', 'Hello, world!');
```
这样就完成了 Spring Boot 和 Socket.IO 的整合。
