QPID例子二（DEMO）

首先确保QPID breaker已经正常运行



目录结构如下



1、创建一个QpidHelloWorld.java

package com;

import java.io.InputStream;
import java.util.Properties;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.MessageConsumer;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.naming.InitialContext;

public class QpidHelloWorld {

public static void main(String[] args) {
QpidHelloWorld hello = new QpidHelloWorld();
hello.runTest();
}

private void runTest()
{
try
{
InputStream resourceAsStream = this.getClass().getResourceAsStream("hello.properties");
Properties properties = new Properties();
properties.load(resourceAsStream);
//使用配置文件创建JNDI的上下文  这里指的是PropertiesFileInitialContextFactory
Context context = new InitialContext(properties);
//从JNDI中获取连接工厂 qpidConnectionfactory
ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("qpidConnectionfactory");
//使用连接工厂创建连接  amqp://guest:guest@test/?brokerlist='tcp://localhost:5672'
//格式如下 amqp://[<user>:<pass>@][<clientid>]<virtualhost>[?<option>='<value>'[&<option>='<value>']]
//brokerlist的格式 如下 brokerlist=<transport>://<host>[:<port>](?<param>='<value>')(&<param>='<value>')*
Connection connection = connectionFactory.createConnection();
connection.start();
//在连接内创建会话
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
//从JNDI中获取目的地址  这里的目的地址是 amq.topic
//This exchange type is used to support the classic publish/subscribe paradigm.
//amp.topic 类似于 jms的 发布/订阅  模式
Destination destination = (Destination) context.lookup("topicExchange");
//从会话中产生生产者与消费者
MessageProducer messageProducer = session.createProducer(destination);
MessageConsumer messageConsumer = session.createConsumer(destination);
//产生文本消息
TextMessage message = session.createTextMessage("Hello world!");
//发送文本消息
messageProducer.send(message);
//接收消息
//This call blocks indefinitely until a message is produced or until this message consumer is closed.
message = (TextMessage)messageConsumer.receive();
System.out.println(message.getText());
//关闭资源连接
connection.close();
context.close();
}
catch (Exception exp)
{
exp.printStackTrace();
}
}
}

2、同级目录下，创建hello.properties

#
java.naming.factory.initial = org.apache.qpid.jndi.PropertiesFileInitialContextFactory

# register some connection factories
# connectionfactory.[jndiname] = [ConnectionURL]
connectionfactory.qpidConnectionfactory = amqp://guest:guest@test/?brokerlist='tcp://172.20.184.218:5672'

# Register an AMQP destination in JNDI
# destination.[jniName] = [Address Format]
destination.topicExchange = amq.topic

如果出现Unsupported major.minor version 51.0异常，那是可能你下载的qpid
jar包的编译版本太高，一个方法反编译jar包重新编译，另一个方法提高jdk版本，例如apache-qpid-jms-0.5.0下载下来则是jdk1.7编译的
