在Spring Boot中，可以使用WebSocket的RabbitMQ消费者和WebSocket客户端来实现主动推送信息到客户端。

首先，你需要在Spring Boot项目中添加RabbitMQ依赖。如果你使用的是Maven，可以在pom.xml文件中添加如下依赖：

xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency>

然后，你需要创建一个WebSocket消费者和客户端。WebSocket消费者用于接收WebSocket连接，并处理WebSocket消息。客户端用于与WebSocket消费者交互，发送和接收WebSocket消息。

以下是一个简单的WebSocket消费者和客户端的示例：

WebSocket Consumer：

```java import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.web.socket.WebSocketChannel; import org.springframework.web.socket.WebSocketMessage; import org.springframework.web.socket.WebSocketSession; import org.springframework.web.socket.client.WebSocketClient; import org.springframework.web.socket.handler mensajeserverHandler;

@SpringBootApplication public class WebsocketConsumerApplication {

public static void main(String[] args) {
    SpringApplication.run(WebsocketConsumerApplication.class, args);
}

@WebSocketChannel
public class WebSocketConsumer {

    private final WebSocketClient webSocketClient;

    public WebSocketConsumer(WebSocketClient webSocketClient) {
        this.webSocketClient = webSocketClient;
    }

    @Override
    public void handleMessage(WebSocketSession session, WebSocketMessage message) {
        String messageText = message.getText();
        // 处理WebSocket消息
    }
}

@WebSocketClient
public class WebSocketClient {

    private final WebSocketChannel channel;

    public WebSocketClient(WebSocketChannel channel) {
        this.channel = channel;
    }

    @Override
    public void handleMessage(WebSocketSession session, WebSocketMessage message) {
        // 发送WebSocket消息
        channel.send(messageText);
    }
}

} ```

WebSocket客户端：

```java import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.web.socket.TextWebSocketClient;

@SpringBootApplication public class WebsocketClientApplication {

public static void main(String[] args) {
    SpringApplication.run(WebsocketClientApplication.class, args);
}

@WebSocketClient
public class TextWebSocketClient {

    private final TextWebSocketChannel channel;

    public TextWebSocketClient(TextWebSocketChannel channel) {
        this.channel = channel;
    }

    @Override
    public void handleMessage(WebSocketSession session, WebSocketMessage message) {
        // 发送WebSocket消息
        channel.send(messageText);
    }
}

} ```

以上就是使用Spring Boot和WebSocket实现主动推送信息到客户端的基本步骤。在实际应用中，你可能需要根据具体需求进行调整。
