SpringBoot 集成WebSocket广播模式

SpringBoot 集成WebSocket广播模式

1.添加maven依赖

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-thymeleafartifactId>
dependency>

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-webartifactId>
dependency>

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-websocketartifactId>
dependency>

2.配置WebSocket

/**
 * 配置WebSocket
 * @author 陈梓平
 * @date 2017/10/26.
 */

@Configuration
//注解用于开启使用STOMP协议来传输基于代理（MessageBroker）的消息
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    /**
     * 配置消息代理
     * @param registry
     */
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic","/user");//服务器发送给客户端的前缀
        //registry.setApplicationDestinationPrefixes("/app");//设置客户端发送给服务器的前缀
       // registry.setUserDestinationPrefix("/user/");//用户目标的前缀
    }

    /**
     *注册一个Stomp的节点（endpoint）,并指定使用SockJS协议。
     * @param stompEndpointRegistry
     */
    @Override
    public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {
        //通过/app/clientLink来发送消息到服务端。
        //添加访问域名限制可以防止跨域socket连接
        stompEndpointRegistry.addEndpoint("/clientLink").withSockJS();
    }
}

3.Controller测试

/**
 * Controller测试
 * @author 陈梓平
 * @date 2017/10/26.
 */
@Controller
@RequestMapping
public class TestController {
    @MessageMapping("/send")
    @SendTo("/topic/msgInfo")
    public MsgInfo msgInfo(String msg,String name){
        MsgInfo msgInfo = new MsgInfo();
        msgInfo.setCreator(name);
        msgInfo.setMsgBody(msg);
        msgInfo.setsTime(Calendar.getInstance());
        return msgInfo;
    }
    @GetMapping(value = "ws")
    public String ws(){
        return "ws";
    }
}

4、前端html

"http://www.thymeleaf.org">

    "UTF-8" />
    
    
    
    

注：需要引入stomp.js和sockjs.min.js

    <script src="http://cdn.bootcss.com/sockjs-client/1.1.1/sockjs.min.js">script>
    <script src="http://cdn.bootcss.com/stomp.js/2.3.3/stomp.js">script>
