Android 使用rabbitmq实现点对点的推送
在实际项目中，客户的推送通知不需要类似极光推送或者友盟的推送，后端人员实现了通过 mq实现点对点的推送通知。作为移动端的，实现起来还是很简单的。
1. 首先依赖：
implementation 'com.rabbitmq:amqp-client:4.1.0'2.在需要接收通知的地方：
//这是一些配置信息：
private void setupConnectionFactory() {
try {
factory=new ConnectionFactory();
factory.setHost("10.121.81.21");
factory.setPort(5672);
factory.setUsername("admin");
factory.setPassword("admin");
factory.setVirtualHost("/mq");
//用于从线程中获取数据，更新ui
//开启消费者线程
//subscribe(incomingMessageHandler);
new Thread(new Runnable() {
@Override
public void run() {
basicConsume();
}
}).start();
}
catch (Exception e){
e.printStackTrace();
}
} /**
* 收消息（从发布者那边订阅消息）
*/
private void basicConsume(){
try {
//连接
Connection connection = factory.newConnection() ;
//通道
final Channel channel = connection.createChannel();
String lineid=CrewApplication.getLoginInfo().getLineId().get(0);
String username = CrewApplication.loginName;
//${plat}.${sys}.${role}.${org}.${line}.${user}
String quene="app.cw.n.n.n."+lineid+"."+username;
// String quene = "app.cw.n.n.n.2.Y10248";
//注册queue
Map arguments = new HashMap();
arguments.put("x-expires",86400000);
arguments.put("x-message-ttl",86400000);
channel.queueDeclare(quene, true, false, true, arguments);
//绑定各种注册后的队列
channel.queueBind(quene, "line_exchange", "app.cw.n.n.n."+lineid+".*");
channel.queueBind(quene, "user_exchange", quene);
channel.queueBind(quene, "plat_exchange", "app.*.*.*.*.*.*");
channel.queueBind(quene, "sys_exchange", "app.cw.*.*.*.*.*");
channel.queueBind(quene, "role_exchange", "app.cw.n.*.*.*.*");
channel.queueBind(quene, "org_exchange", "app.cw.n.n.*.*.*");
channel.queueBind(quene, "post_exchange", "app.cw.n.n.n.*.*");
//实现Consumer的最简单方法是将便捷类DefaultConsumer子类化。可以在basicConsume 调用上传递此子类的对象以设置订阅：
channel.basicConsume(quene , false , new DefaultConsumer(channel){
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
super.handleDelivery(consumerTag, envelope, properties, body);
//这里接收到推送，我和后台人员定好了接收String json串
String msg = new String(body) ;
// EventBus.getDefault().postSticky(msg);
long deliveryTag = envelope.getDeliveryTag() ;
channel.basicAck(deliveryTag , false);
Log.d("通知测试", msg);
//
Gson gson = new Gson();
NotificationBean notificationBean = gson.fromJson(msg, NotificationBean.class);
String content = notificationBean.getContent();
//以通知的形式展示以及跳转
if (notificationBean.getYmState().equals("2")) {
Intent intent1 =new Intent (MainActivity.this, Notification2ClickReceiver.class);
intent1.putExtra("pageState", msg);
NotificationUtils notificationUtils = new NotificationUtils(MainActivity.this, intent1);
notificationUtils.sendNotification(notificationBean.getTitle(), content);
} else if (notificationBean.getYmState().equals("1")){
//这是主界面的跳转
Intent intent2 =new Intent (MainActivity.this, Notification1ClickReceiver.class);
intent2.putExtra("pageState", "1");
NotificationUtils notificationUtils = new NotificationUtils(MainActivity.this, intent2);
notificationUtils.sendNotification(notificationBean.getTitle(), content);
} else if (notificationBean.getYmState().equals("3")) {
Intent intent3 =new Intent (MainActivity.this, Notification3ClickReceiver.class);
intent3.putExtra("pageState", "3");
NotificationUtils notificationUtils = new NotificationUtils(MainActivity.this, intent3);
notificationUtils.sendNotification(notificationBean.getTitle(), content);
}
//从message池中获取msg对象更高效
// Message uimsg = handler.obtainMessage();
// Bundle bundle = new Bundle();
// bundle.putString("msg", msg);
// uimsg.setData(bundle);
// handler.sendMessage(uimsg);
}
});
} catch (IOException e) {
e.printStackTrace();
} catch (TimeoutException e) {
e.printStackTrace();
}
}
