java springboot socket 用法

Spring Boot与Socket结合通常用于构建实时通信应用,如WebSocket服务。以下是基本的步骤:
1. **添加依赖**:在你的`pom.xml`中添加Spring Websocket相关的依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```
2. **创建配置类**:启用WebSocket支持,并指定特定的处理器:
```java
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/websocket").withSockJS();
}
}
```
这里,`@EnableWebSocketMessageBroker`开启WebSocket消息代理,`configureMessageBroker`设置主题前缀和应用前缀。
3. **编写处理器**:创建处理客户端连接、消息发送和接收的控制器:
```java
@Controller
public class ChatController {
@MessageMapping("/chat")
@SendTo("/topic/messages")
public ChatResponse sendMessage(ChatRequest message) throws Exception {
// 实现业务逻辑,比如持久化消息到数据库
return new ChatResponse("Received your message: " + message.getText());
}
}
```
4. **前端连接和交互**:使用JavaScript库(如SockJS和Stomp.js)与服务器建立连接并发送/接收消息。
