概述与介绍

ActiveMQ 是Apache出品，最流行的. 功能强大的即时通讯和集成模式的开源服务器。

ActiveMQ 是一个完全支持JMS1.1和J2EE 1.4规范的 JMS Provider实现。

提供客户端支持跨语言和协议，带有易于在充分支持JMS 1.1和1.4使用J2EE企业集成模式和许多先进的功能。

特性

多种语言和协议编写客户端。语言： Java. C. C++. C#. Ruby. Perl. Python. PHP。应用协议：OpenWire. Stomp REST. WS Notification. XMPP. AMQP
完全支持JMS1.1和J2EE 1.4规范（持久化，XA消息，事务)
对Spring的支持，ActiveMQ可以很容易内嵌到使用Spring的系统里面去，而且也支持Spring2.0的特性
通过了常见J2EE服务器（如 Geronimo. JBoss 4. GlassFish. WebLogic)的测试，其中通过JCA 1.5 resource adaptors的配置，可以让ActiveMQ可以自动的部署到任何兼容J2EE 1.4 商业服务器上
支持多种传送协议：in-VM. TCP. SSL. NIO. UDP. JGroups. JXTA
支持通过JDBC和journal提供高速的消息持久化

从设计上保证了高性能的集群，客户端-服务器，点对点
支持Ajax
支持与Axis的整合
可以很容易得调用内嵌JMS provider，进行测试

本文基于最新版的ActiveMQ 5.15.0进行讲解, 期间遇到的问题也是这个版本出现的, 解决方法也会在文中记录

1.下载

ActiveMQ 5.15.0下载地址

2.安装

2.1解压apache-activemq-5.15.0-bin.zip

本文解压在D盘根目录

activemq-bin

2.2启动activemq

activemq-start01

2.2.1普通启动命令

按下: win+r, 输入cmd, 进入dos界面:

open-cmd

//3条命令的意思分别是:
//1.进入activemq的bin目录
//2.进入d盘
//3.启动activemq

cd D:\apache-activemq-5.15.0\bin
d:
activemq start

如果你启动看到了异常信息：

Caused by: java.io.IOException: Failed to bind to server socket: tcp://0.0.0.0:61616?maximumConnections=1000&wireformat.maxFrameSize=104857600 due to: java.net.SocketException: Unrecognized Windows Sockets error: 0: **JVM_Bind**

原因是:

你的端口被占用了。找到是哪个程序占用了你的端口, 并kill掉该进程或服务。或者尝试修改ActiveMQ的默认端口61616（ActiveMQ使用的默认端口是61616）, 在大多数情况下，占用61616端口的是Internet Connection Sharing (ICS) 这个Windows服务，你只需停止它就可以启动ActiveMQ了。

启动成功:

启动完成访问http://127.0.0.1:8161/

1.访问: http://127.0.0.1:8161/,再点击Manage ActiveMQ broker

web管理页面

进入管理页面, 帐号密码都是: admin

输入帐号密码

进入admin页面, 也可以直接进入http://127.0.0.1:8161/admin/, 输入帐号密码: admin即可

进入admin页面

导航菜单中

Queues是队列方式消息
Topics是主题方式消息
Subscribers消息订阅监控查询
Connections可以查看链接数，分别可以查看xmpp、ssl、stomp、openwire、ws和网络链接
Network是网络链接数监控
Send可以发送消息数据。

如果你想修改用户名和密码的话，在conf/jetty-realm.properties中修改即可。

2.2.2运行demo示例

遇到的问题:

使用官方文档提供的启动方式启动ActiveMQ v5.15，
bin/activemq console xbean:examples/conf/activemq-demo.xml
不能启动，activemq中没有console 参数。
解决办法:

不同版本启动命令不一样!

1、V5.8使用下面的命令行启动
D:\apache-activemq-5.8.0\bin>activemq xbean:../conf/activemq-demo.xml
2、V5.9使用下面的命令行启动
D:\apache-activemq-5.9.1\bin>activemq xbean:../examples/conf/activemq-demo.xml
3、V5.15.0使用下面的命令行启动
D:\apache-activemq-5.15.0\bin>activemq start xbean:file:../examples/conf/activemq-demo.xml

当然你还可以用绝对的文件目录方式：activemq start xbean:file:D:\apache-activemq-5.15.0\conf/activemq-demo.xml

输入命令启动

activemq start xbean:file:../examples/conf/activemq-demo.xml

运行demo示例

访问: http://localhost:8161/demo/ , 点击Websockets

3.使用

3.1消息示例

3.1.1ActiviteMQ消息有3种形式

JMS 公共	点对点域	发布/订阅域
ConnectionFactory	QueueConnectionFactory	TopicConnectionFactory
Connection	QueueConnection	TopicConnection
Destination	Queue	Topic
Session	QueueSession	TopicSession
MessageProducer	QueueSender	TopicPublisher
MessageConsumer	QueueReceiver	TopicSubscriber

点对点方式（point-to-point）

点对点的消息发送方式主要建立在 Message Queue,Sender,reciever上，Message Queue 存贮消息，Sneder 发送消息，receive接收消息.具体点就是Sender Client发送Message Queue ,而 receiver Cliernt从Queue中接收消息和"发送消息已接受"到Quere,确认消息接收。消息发送客户端与接收客户端没有时间上的依赖，发送客户端可以在任何时刻发送信息到Queue，而不需要知道接收客户端是不是在运行

发布/订阅方式（publish/subscriber Messaging）

发布/订阅方式用于多接收客户端的方式.作为发布订阅的方式，可能存在多个接收客户端，并且接收端客户端与发送客户端存在时间上的依赖。一个接收端只能接收他创建以后发送客户端发送的信息。作为subscriber ,在接收消息时有两种方法，destination的receive方法，和实现message listener 接口的onMessage 方法。

3.1.2ActiviteMQ接收和发送消息基本流程

基本流程

发送消息的基本步骤：

(1)、创建连接使用的工厂类JMS ConnectionFactory

(2)、使用管理对象JMS ConnectionFactory建立连接Connection，并启动

(3)、使用连接Connection 建立会话Session

(4)、使用会话Session和管理对象Destination创建消息生产者MessageSender

(5)、使用消息生产者MessageSender发送消息

消息接收者从JMS接受消息的步骤

(1)、创建连接使用的工厂类JMS ConnectionFactory

(2)、使用管理对象JMS ConnectionFactory建立连接Connection，并启动

(3)、使用连接Connection 建立会话Session

(4)、使用会话Session和管理对象Destination创建消息接收者MessageReceiver

(5)、使用消息接收者MessageReceiver接受消息，需要用setMessageListener将MessageListener接口绑定到MessageReceiver消息接收者必须实现了MessageListener接口，需要定义onMessage事件方法。

3.1.3使用java代码实现收发消息

1.使用JMS方式发送接收消息

收到消息：current system time: 1506866100187

5.在springboot中使用ActiveMQ

pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>

application.yml

spring:
  application:
    name: activemq-demo
server:
  port: 9090

发送方

/**
 * @author Dragon
 * @version V0.1
 * @Title: com.dragon.activemq.demo.springboot.demo.MessageProduction
 * @Description: 消息生产者
 * @date 2017/10/01 23:14
 */
//注册为一个bean
@Component
//开启定时器
@EnableScheduling
public class MessageProduction {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;//使用JmsMessagingTemplate将消息放入队列

    @Autowired
    private Queue queue;

    @Scheduled(fixedDelay = 3000)//每3s执行1次,将消息放入队列内
    public void send() {
        this.jmsMessagingTemplate.convertAndSend(this.queue,
            "测试消息队列" + System.currentTimeMillis() / 1000);
    }
}

输出

消息队列

/**
 * @author Dragon
 * @version V0.1
 * @Title: com.dragon.activemq.demo.springboot.demo.MessageQueue
 * @Description: 队列消息发送者
 * @date 2017/10/01 23:16
 */
@Component
public class MessageQueue {

    //返回一个名为my-message的队列,并且注册为bean
    @Bean
    public Queue queue() {
        return new ActiveMQQueue("my-message");
    }

}

接收方

package com.dragon.activemq.demo.springboot.demo;

import com.dragon.activemq.demo.springboot.Constants;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import java.text.MessageFormat;
import java.util.Date;

/**

 * @version V0.1
 * @Title: com.dragon.activemq.demo.springboot.demo.MessageListener
 * @Description: 消息监听者
 * @date 2017/10/01 23:16
 */
@Component
public class MessageListener {

    /**
     * 使用@JmsListener注解来监听指定的某个队列内的消息,是否有新增,有的话则取出队列内消息
     * 进行处理
     **/
    @JmsListener(destination = "my-message")
    public void removeMessage(String msg) {
    //public void removeMessage(Email email) {
        System.out.println("监听接收到的消息是:" + msg);//打印队列内的消息
    }
  
    /*@JmsListener(destination = "mailbox", containerFactory = "myFactory")
    public void receiveMessage(Email email) {
        System.out.println("Received <" + email + ">");
    }*/

}

启动ActiveMQApplication后的输出

监听接收到的消息是:测试消息队列1506875404
监听接收到的消息是:测试消息队列1506875407
监听接收到的消息是:测试消息队列1506875410

    }

}

4.遇到的坑

4.1消息类型转换错误

Caused by: org.springframework.messaging.converter.MessageConversionException: Cannot convert from [org.apache.activemq.command.ActiveMQTextMessage] to [com.dragon.activemq.demo.springboot.demo.Email] for org.springframework.jms.listener.adapter.AbstractAdaptableMessageListener$MessagingMessageConverterAdapter$LazyResolutionMessage@3189b1ff

解决方法:

在application类里加个bean

    @Bean // Serialize message content to json using TextMessage
    public MessageConverter jacksonJmsMessageConverter() {
        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setTargetType(MessageType.TEXT);
        converter.setTypeIdPropertyName("_type");
        return converter;
    }

4.2发送消息之后消费不了

解决方法:

将springboot里的消息加到jms工厂

    @Bean
    public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,
                                                    DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        // This provides all boot's default to this factory, including the message converter
        configurer.configure(factory, connectionFactory);
        // You could still override some of Boot's default if necessary.
        return factory;
    }

4.3实体类序列化后报错

Caused by: org.springframework.jms.support.converter.MessageConversionException: Could not convert JMS message; nested exception is javax.jms.JMSException: Failed to build body from content. Serializable class not available to broker. Reason: java.lang.ClassNotFoundException: Forbidden class com.dragon.activemq.demo.springboot.demo.Email! This class is not trusted to be serialized as ObjectMessage payload. Please take a look at http://activemq.apache.org/objectmessage.html for more information on how to configure trusted classes.

报错的详细讲解
http://activemq.apache.org/objectmessage.html

解决方法:

设置可以序列化的包列表, 加到vm启动参数里面!

#全部包
#org.apache.activemq.SERIALIZABLE_PACKAGES=*
org.apache.activemq.SERIALIZABLE_PACKAGES=com.dragon.activemq,com.dragon.demo

加到vm启动参数里面
