前端WebSocket客户端实现

// 创建WebSocket连接
var socket = new WebSocket('ws://your-spring-boot-server-url/websocket-endpoint');// 连接打开时触发
socket.addEventListener('open', function (event) {socket.send(JSON.stringify({type: 'JOIN', room: 'general'}));
});// 监听从服务器来的消息
socket.addEventListener('message', function (event) {console.log('Message from server ', event.data);
});// 连接关闭时触发
socket.addEventListener('close', function (event) {console.log('Socket is closed. Reconnect will be attempted in 1 second.', event);
});

Vue.js示例
如果你的应用是基于Vue.js的，你可以直接在Vue组件中使用WebSocket，或者考虑使用如vue-socket.io这样的插件来简化开发过程。下面是一个基本的Vue组件中集成WebSocket的例子：

export default {data() {return {socket: null}},mounted() {this.socket = new WebSocket('ws://your-spring-boot-server-url/websocket-endpoint');this.socket.onopen = (event) => {console.log('WebSocket connection opened!', event);this.socket.send(JSON.stringify({action: 'subscribe', topic: 'news'}));};this.socket.onmessage = (event) => {console.log('Received message:', event.data);};this.socket.onclose = (event) => {console.log('WebSocket connection closed.', event);};},beforeDestroy() {if (this.socket) {this.socket.close();}}
}
