在Spring Boot中使用WebSocket作为客户端接收实时数据通常涉及以下几个步骤:
1. 添加依赖:首先,在项目的pom.xml或build.gradle文件中添加WebSocket相关的依赖,如Spring Websocket或SockJS等。对于Spring Boot,你可以使用`spring-boot-starter-websocket`。
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
```
2. 配置Starter:在application.properties或application.yml中配置WebSocket支持。
```properties
server.webSocket.enabled=true
```
3. 创建WebSocketClient:创建一个实现了`CloseableSession`接口的类,并通过`WebSocketTemplate`来操作WebSocket连接。
```java
@Autowired
private WebSocketOperations webSocketOperations;
public void subscribeToChannel(ChannelName channel) {
StompHeaderAccessor accessor = StompHeaderAccessor.createFrameHeader();
accessor.setCommand(StompCommand.SUBSCRIBE);
accessor.setDestination("/app/" + channel);
this.websocketOperations.sendTextMessage(accessor.getMessage(), null); // 发送订阅请求
}
```
4. 接收消息:在客户端,你需要监听WebSocket的消息事件,例如`MessageReceivedEvent`。
```java
@EventListener
public void onMessageReceived(MessageReceivedEvent event) {
String message = event.getMessage().getBody(String.class);
System.out.println("Received message: " + message);
}
```
5. 关闭连接:当不再需要连接时,记得调用`close()`方法关闭WebSocket连接。
```java
@Override
public void onClose(CloseReason reason) {
if (reason.getCloseCode() == CloseCodes.NORMALClosure.getValue()) {
log.info("Connection closed normally");
} else {
log.error("Unexpected close reason: {}", reason);
}
webSocketOperations.close();
}
```
