node(ActiveMq)

简单尝试了node下的ActiveMQ

1、下载apache-activemq-5.9.0，执行bat文件；

2、登录http://localhost:8161/admin可查看其管理后台；

3、安装stomp客户端 npm install stomp-client

4、修改基础代码如下：

var Stomp = require('stomp-client');
var readline = require('readline');
//创建两个不同的topic
var topic1 = '/topic/topic1';
var topic2 = '/topic/topic2';
 
var rl = readline.createInterface({
    input : process.stdin,
    output : process.stdout,
    terminal : false
});
 
//1. publisher-subscribe 定义一个或者多个topic，然后给这些topic发送消息
//2. p2p 双方通过一个quene来发送、接收消息,一个quene只有一个发送、一个接收
//3. request-response 双方各有一个quene作为彼此的收发，相当于两个p2p
 
var publisher = new Stomp('127.0.0.1', 61613, '', ''); //发布者
var subscriberA = new Stomp('127.0.0.1', 61613, '', ''); //订阅者A
var subscriberB = new Stomp('127.0.0.1', 61613, '', ''); //订阅者B
 
publisher.connect(function(sessionId) {
    rl.on('line', function(line) {
        switch (line.split(":")[0]) {
 
        case 'topic1':
            publisher.publish(topic1, line.split(":")[1]);
            break;
        case 'topic2':
            publisher.publish(topic2, line.split(":")[1]);
            break;
        default:
            console.log('commond error `' + line.trim() + '`');
            break;
        }
        rl.prompt();
    }).on('close', function() {
        console.log('close test project!');
        process.exit(0);
    });
});
 
subscriberA.connect(function(sessionId) {
    subscriberA.subscribe(topic1, function(body, headers) {
        console.log('subscriberA From Topic1:', body);
    });
    subscriberA.subscribe(topic2, function(body, headers) {
        console.log('subscriberA From Topic2:', body);
    });
});
 
subscriberB.connect(function(sessionId) {
    subscriberB.subscribe(topic1, function(body, headers) {
        console.log('subscriberB From Topic1:', body);
    });
    subscriberB.subscribe(topic2, function(body, headers) {
        console.log('subscriberB From Topic2:', body);
    });
});

输入不同命令后，控制台输出如下：

同时在管理后台的topic栏目下，查看创建的topic
