RabbitMQ是什么 ？
RabbitMQ是一个在AMQP基础上完整的，可复用的企业消息系统。他遵循Mozilla Public License开源协议。
1：安装RabbitMQ需要先安装Erlang语言开发包。下载地址 http://www.erlang.org/download.html 在win7下安装Erlang最好默认安装。
配置环境变量 ERLANG_HOME C:\Program Files (x86)\erl5.9
添加到PATH %ERLANG_HOME%\bin;
2：安装RabbitMQ 下载地址 http://www.rabbitmq.com/download.html 安装教程：http://www.rabbitmq.com/install-windows.html
配置环境变量 C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-2.8.0
添加到PATH %RABBITMQ_SERVER%\sbin;
3：进入%RABBITMQ_SERVER%\sbin 目录以管理员身份运行 rabbitmq-plugins.bat
安装完成之后以管理员身份启动 rabbitmq-service.bat
4：浏览器访问localhost:55672 默认账号：guest 密码：guest
创建队列名称为queue_sina ，java示例代码读写队列中queue_sina的消息queue_sina
private static final String exchangeName = “sina”;
private static final String exchangeRoutingKey = “sina”;
HashMap<String,String> map = new HashMap<String,String>();
map.put(“text”, request.getText());
map.put(“image”, imageUrl);
map.put(“nick_name”, this.getUserName(request.getUserid()));
map.put(“shop_name”, request.getShopname());
String tousu_map = gson.toJson(map, new TypeToken<HashMap<String,String>>(){}.getType());
System.out.println(“tousu_map” + tousu_map);
//写入队列
Producer.sendMsg(PropsUtils.getInstance().getProperty(Constants.EXCHANGE_NAME,
exchangeName), PropsUtils.getInstance()
.getProperty(Constants.EXCHANGE_ROUTING_KEY,
exchangeRoutingKey), tousu_map);
//写入队列模版类
public class Producer {
private static AmqpTemplate amqpTemplate = null;
static {
ApplicationContext context = new AnnotationConfigApplicationContext(TousuConfiguration.class);
amqpTemplate = context.getBean(AmqpTemplate.class);
}
public static void sendMsg(String exchangeName,String routingKey,Object message){
amqpTemplate.convertAndSend(exchangeName, routingKey,message);
System.out.println(“exchangeName: “+exchangeName);
System.out.println(“routingKey: “+routingKey);
System.out.println(“Sent : “+message);
}
}
//读取队列消息
public static void main(String[] args) {
//test
try {
//队列名称 PropertiesUtil.QUEUE_NAME=queue_sina
String queueName = PropertiesUtil.QUEUE_NAME;
ConnectionFactory factory = new ConnectionFactory();
//PropertiesUtil.HOST = localhost
factory.setHost(PropertiesUtil.HOST);
//PropertiesUtil.USER=guest
factory.setUsername(PropertiesUtil.USER);
//PropertiesUtil.PASS=guest
factory.setPassword(PropertiesUtil.PASS);
//PropertiesUtil.PORT=5672
factory.setPort(Integer.parseInt(PropertiesUtil.PORT));
Connection conn = factory.newConnection();
Channel channel = conn.createChannel();
channel.queueDeclare(queueName, true, false, false, null);
QueueingConsumer consumer = new QueueingConsumer(channel);
channel.basicConsume(queueName, true, consumer);
while(true) {
try {
QueueingConsumer.Delivery delivery = consumer.nextDelivery();
String message = new String(delivery.getBody());
System.out.println(” [x] Received ‘” + message + “‘”);
} catch (ShutdownSignalException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
