在这里插入图片描述

一，思路梳理

1，首先思考群聊的实现方式。
2，再来举一反三，思考单聊的实现方式。
有一个地方需要提一下，比如要给A用户发送消息，就要根据A的userId得到连接对象，然后就会把消息发送给A用户。

二，代码分析

1，首先是用户聊天框的js代码（html忽略）
此为用户点击在线客服按钮进入聊天框页面就执行的js代码。

说明：下面接收人id写死了为超级管理员，我这里省事情了，因为超级管理员的账号（也就是唯一标识）就是超级管理员这五个字，当真正开发时就要动态获取唯一标识了！

三，依赖注入

在websocket中进行依赖注入service并调用service方法进行数据库存储，如果按常规的方式是走不通的。

解决方式：

在该springboot项目中添加一个WebsocketConfig配置类，对service进行配置。

<span style="color:#314659"><span style="background-color:#ffffff"><code class="language-java"><span style="color:#fd971f !important">@Configuration</span>
<span style="color:#4078f2 !important">public</span> <span style="color:#4078f2 !important">class</span> <span style="color:#50a14f !important">WebSocketConfig</span> {
    <span style="color:#999999 !important"><em>/**
     * ServerEndpointExporter 用于扫描和注册所有携带 ServerEndPoint 注解的实例，
     * 若部署到外部容器 则无需提供此类。
     */</em></span>
    <span style="color:#fd971f !important">@Bean</span>
    <span style="color:#4078f2 !important">public</span> ServerEndpointExporter <span style="color:#50a14f !important">serverEndpointExporter</span>() {
        <span style="color:#4078f2 !important">return</span> <span style="color:#4078f2 !important">new</span> <span style="color:#50a14f !important">ServerEndpointExporter</span>();
    }

    <span style="color:#999999 !important"><em>

    
     * 因 SpringBoot WebSocket 对每个客户端连接都会创建一个 WebSocketServer（<span style="color:#c678dd">@ServerEndpoint</span> 注解对应的对象，Bean 注入操作会被直接略过，因而手动注入一个全局变量
     */</em></span>
    <span style="color:#fd971f !important">@Autowired</span>
    <span style="color:#4078f2 !important">public</span> <span style="color:#4078f2 !important">void</span> <span style="color:#50a14f !important">setSelectService</span>(SelectService selectService) {
        ChatRoomServer.selectService = selectService;
    }
}
</code></span></span>

然后在websocket中注入service。
