修改 blade-demo模块
pom文件增加依赖
org.springframework.boot spring-boot-starter-websocket
增加WebSocketAutoConfig 文件
package com.example.demo.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketAutoConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/bullet","/websocket") //开启/bullet端点
.setAllowedOrigins("*") //允许跨域访问
.withSockJS(); //使用sockJS
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
//订阅Broker名称
//registry.enableSimpleBroker("/topic","/user");
registry.enableSimpleBroker("/toAll","/topic");
//全局使用的订阅前缀（客户端订阅路径上会体现出来）
//registry.setApplicationDestinationPrefixes("/app/");
//
//点对点使用的订阅前缀（客户端订阅路径上会体现出来），不设置的话，默认也是/user/
//registry.setUserDestinationPrefix("/user/");
}
}增加BulletController
package com.example.demo.controller;
import com.example.demo.dto.BulletMessageDTO;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class BulletController {
private static final Logger logger=LoggerFactory.getLogger(BulletController.class);
@MessageMapping("/hellowebsocket")
//SendTo 发送至 Broker 下的指定订阅路径
@SendTo("/topic/helloworld")
// @SendTo("/toAlltoAll/bulletScreen")
public String say(BulletMessageDTO clientMessage) {
//方法用于广播测试
if (clientMessage!=null){
if (clientMessage.getMessage()!=null){
clientMessage.setMessage(clientMessage.getMessage().trim());
}
}
logger.info(clientMessage.getUsername()+":"+clientMessage.getMessage());
return clientMessage.getMessage();
}
//注入SimpMessagingTemplate 用于点对点消息发送
@Autowired
private SimpMessagingTemplate messagingTemplate;
@RequestMapping("/send")
public void send(String msg){
messagingTemplate.convertAndSend("/topic/helloworld", msg + "hello!!!");
}
