SpringBoot实现WebSocket群聊

一、创建项目并导入依赖

   

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-websocket</artifactId>

</dependency>

<!--https://mvnrepository.com/artifact/org.webjars/sockjs-client-->

<dependency>

<groupId>org.webjars</groupId>

<artifactId>sockjs-client</artifactId>

<version>1.1.2</version>

</dependency>

<!--https://mvnrepository.com/artifact/org.webjars.bower/jquery-->

<dependency>

<groupId>org.webjars.bower</groupId>

<artifactId>jquery</artifactId>

<version>3.4.1</version>

</dependency>

   

<!--https://mvnrepository.com/artifact/org.webjars/stomp-websocket-->

<dependency>

<groupId>org.webjars</groupId>

<artifactId>stomp-websocket</artifactId>

<version>2.3.3</version>

</dependency>

<!--https://mvnrepository.com/artifact/org.webjars/webjars-locator-core-->

<dependency>

<groupId>org.webjars</groupId>

<artifactId>webjars-locator-core</artifactId>

<version>0.38</version>

</dependency>

   

注：我这里js文件用jar代替，其实和jar包效果用法一样

   

二、相关配置代码

   

2.1）创建一个WebSocketConfig配置文件并实现WebSocketMessagerBrokerConfigurer

   

2.2）在类上方加如下注解

   

   

2.3）重写方法

   

   

2.4）Message实体类

   

2.5）controller

   

下面两个写法一样

   

   

2.6）前端chat.html
