1.package.json中

"dependencies": {
 ...
 "vertx3-eventbus-client": "3.5.2",
 },

然后  npm install，或者：

npm install vertx3-eventbus-client@3.5.2

2.angular-cli.json中

 "scripts": [
 ...
 "../node_modules/vertx3-eventbus-client/vertx-eventbus.js"
 ],

3.创建一个eventbus.service.ts用来通信

导入eventbus：

import { EventBus } from 'vertx3-eventbus-client';

声明eventbus:

declare var EventBus: any;

4.创建eventbus实例，监听接口以及发送消息

//创建实例
var eb = new EventBus('http://localhost:8080/eventbus');

eb.onopen = function() {
 //注册用来接受消息
 eb.registerHandler('some-address', function(error, message) {
 console.log('received a message: ' + JSON.stringify(message));
 });

 //发送消息
 eb.send('some-address', {name: 'tim', age: 587});

}

更多信息请参考这里 https://vertx.io/docs/vertx-web/java/

注：

对于需要发送消息来接受的消息，需要先监听，然后再发送消息。
对于一直推送的消息，不需要发送。

代码实例如下：

RegisterHandler(key, id, callback) {
 const address = '***.' + key + '.' + id;
 if (typeof (this.eventBus[key]) === 'undefined' || !this.eventBus[key]) {
 this.eventBus[key] = new EventBus(environment.eventbusUrl);
 }
 if (this.eventBus[key].state === EventBus.OPEN) {
 this.eventBus[key].registerHandler(address, callback);
 } else {
 const $this = this;
 this.eventBus[key].onopen = function () {
 $this.eventBus[key].registerHandler(address, callback)
 }
 }
 }

Send(key, id) {
 var data = '';
 const address = ***.' + key + '.' + id;
 if (typeof (this.eventBus[key]) === 'undefined' || !this.eventBus[key]) {
 this.eventBus[key] = new EventBus(environment.eventbusUrl);
 }
 if (this.eventBus[key].state === EventBus.OPEN) {
 this.eventBus[key].send(address, data)
 } else {
 const $this = this;
 this.eventBus[key].onopen = function () {
 $this.eventBus[key].send(address, data)
 }
 }
 }

closeEventBus(key) {
 if (typeof (this.eventBus[key]) !== 'undefined' && this.eventBus[key] && this.eventBus[key].state === EventBus.OPEN) {
 this.eventBus[key].close();
 }
 this.eventBus[key] = null;
}

在组件ngOnDestroy中调用closeEventBus关闭eventbus。
