复制代码

// 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：

复制代码

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();
        }
    }
}
