springboot集成socket

Spring Boot可以很方便地集成Socket，实现WebSocket通信。以下是简单的步骤：

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>

2. 创建WebSocket处理器

创建一个类，实现WebSocketHandler接口，处理WebSocket请求。例如：

@Component
public class MyWebSocketHandler implements WebSocketHandler {

    @Override
    public void afterConnectionEstablished(WebSocketSession session) throws Exception {
        // 连接建立后的处理
    }

    @Override
    public void handleMessage(WebSocketSession session, WebSocketMessage<?> message) throws Exception {
        // 处理收到的消息
    }

    @Override
    public void handleTransportError(WebSocketSession session, Throwable exception) throws Exception {
        // 处理传输错误
    }

    @Override
    public void afterConnectionClosed(WebSocketSession session, CloseStatus closeStatus) throws Exception {
        // 连接关闭后的处理
    }

    @Override
    public boolean supportsPartialMessages() {
        return false;
    }
}

3. 配置WebSocket

在配置类中添加WebSocket配置：

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

    @Autowired
    private MyWebSocketHandler myWebSocketHandler;

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(myWebSocketHandler, "/my-websocket");
    }
}

4. 测试WebSocket

在前端页面中使用JavaScript创建WebSocket连接，发送和接收消息。例如：

var socket = new WebSocket("ws://localhost:808/my-websocket");

socket.onopen = function(event) {
    console.log("WebSocket连接已建立");
};

socket.onmessage = function(event) {
    console.log("收到消息：" + event.data);
};

socket.onclose = function(event) {
    console.log("WebSocket连接已关闭");
};

socket.send("Hello, WebSocket!");

以上是简单的Spring Boot集成Socket的步骤，具体实现还需要根据实际需求进行调整。
