缺少webapp，如果您使用的是tomcat，则需要将war文件复制到war文件夹，如果您的test文件名为http://localhost:8080/test/，则需要请致电const io = require('socket.io')(3000); io.on('connection', function (socket) { console.log('a client has connected'); socket.on('clicked', function() { io.emit('clicked'); }); socket.on('clicked1', function() { io.emit('clicked1'); }); }); console.log('socket.io server started at port 3000'); 获取您的主页，但我强烈建议您不要以这种方式学习弹簧，首先尝试symlinked，这是弹簧的新方法，更简单。

将以下代码用于Application-context.xml路径。
