2.消息实体类

package com.yl.chat01.domain;

import java.io.Serializable;

public class Message implements Serializable {
    private String name;
    private String content;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    @Override
    public String toString() {
        return "Message{" +
                "name='" + name + '\'' +
                ", content='" + content + '\'' +
                '}';
    }
}

3.controller

package com.yl.chat01.controller;

import com.yl.chat01.domain.Message;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Controller;

@Controller
public class GreetingController {

    @MessageMapping("/hello") //发送消息请求
    @SendTo("/topic/greetings") //消息广播
    public Message greeting(Message message) {
        return message;
    }
}

4.WebSocket的配置文件

package com.yl.chat01.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 WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    // 注册端点,用于前端建立连接的
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/chat").withSockJS();
    }

    // 配置消息代理，通过广播的形式来传递消息
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic");
    }
}

5.前端发送消息页面

    
    
    
    
    



    请输入用户名：
    



    
    




    请输入聊天内容
