一、安裝ActiveMQ

具體的安裝步驟，請參考我的另一篇博文：

http://blog.csdn.net/liuchuanhong1/article/details/52057711

二、新建spring boot工程，並加入JMS(ActiveMQ)依賴

三、工程結構

pom依賴如下：

<?xml version=“1.0” encoding=“UTF-8”?>

            </plugin>
        </plugins>
    </build>
</project>

四、修改application.properties配置文件

[java] view plain copy

print?

## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`
# failover:(tcp://localhost:61616,tcp://localhost:61617)
# tcp://localhost:61616
spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false //如果此處設置爲true，需要加如下的依賴包，否則會自動配置失敗，報JmsMessagingTemplate注入失敗

## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`

failover:(tcp://localhost:61616,tcp://localhost:61617)

tcp://localhost:61616

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false //如果此處設置爲true，需要加如下的依賴包，否則會自動配置失敗，報JmsMessagingTemplate注入失敗

[html] view plain copy

print?

<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-pool</artifactId>
<!– <version>5.7.0</version> –>
</dependency>

<dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-pool</artifactId>
            <!-- <version>5.7.0</version> -->
        </dependency>

五、消息生產者

[java] view plain copy

print?

package com.chhliu.springboot.jms;
import javax.jms.Destination;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;
@Service(“producer”)
public class Producer {
@Autowired // 也可以注入JmsTemplate，JmsMessagingTemplate對JmsTemplate進行了封裝
private JmsMessagingTemplate jmsTemplate;
// 發送消息，destination是發送到的隊列，message是待發送的消息
public void sendMessage(Destination destination, final String message){
jmsTemplate.convertAndSend(destination, message);
}
}

package com.chhliu.springboot.jms;

import javax.jms.Destination;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

@Service("producer")
public class Producer {
    @Autowired // 也可以注入JmsTemplate，JmsMessagingTemplate對JmsTemplate進行了封裝
    private JmsMessagingTemplate jmsTemplate;
    // 發送消息，destination是發送到的隊列，message是待發送的消息
    public void sendMessage(Destination destination, final String message){
        jmsTemplate.convertAndSend(destination, message);
    }
}

六、消息消費者

[java] view plain copy

print?

package com.chhliu.springboot.jms;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
@Component
public class Consumer {
// 使用JmsListener配置消費者監聽的隊列，其中text是接收到的消息
@JmsListener(destination = “mytest.queue”)
public void receiveQueue(String text) {
System.out.println(”Consumer收到的報文爲:”+text);
}
}

package com.chhliu.springboot.jms;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class Consumer {
        // 使用JmsListener配置消費者監聽的隊列，其中text是接收到的消息
    @JmsListener(destination = "mytest.queue")
    public void receiveQueue(String text) {
        System.out.println("Consumer收到的報文爲:"+text);
    }
}

消費者2的代碼同上，注意，消息消費者的類上必須加上@Component，或者是@Service，這樣的話，消息消費者類就會被委派給Listener類，原理類似於使用SessionAwareMessageListener以及MessageListenerAdapter來實現消息驅動POJO

七、測試

[java] view plain copy

print?

package com.chhliu.springboot.jms;
import javax.jms.Destination;
import org.apache.activemq.command.ActiveMQQueue;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootJmsApplicationTests {
@Autowired
private Producer producer;
@Test
public void contextLoads() throws InterruptedException {
Destination destination = new ActiveMQQueue(“mytest.queue”);
for(int i=0; i<100; i++){
producer.sendMessage(destination, ”myname is chhliu!!!”);
}
}
}

package com.chhliu.springboot.jms;

import javax.jms.Destination;

import org.apache.activemq.command.ActiveMQQueue;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootJmsApplicationTests {

    @Autowired
    private Producer producer;

    @Test
    public void contextLoads() throws InterruptedException {
        Destination destination = new ActiveMQQueue("mytest.queue");

        for(int i=0; i<100; i++){
            producer.sendMessage(destination, "myname is chhliu!!!");
        }
    }

}

測試結果如下：

[java] view plain copy

print?

Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!

Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!

經過上面的幾個步驟，spring boot和Jms就基本上整合完成了，是不是使用起來很方便了！

八、實現雙向隊列

1、下面首先來對Consumer2這個消費者來進行下改造，代碼如下：

[java] view plain copy

print?

package com.chhliu.springboot.jms;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;
@Component
public class Consumer2 {
@JmsListener(destination = “mytest.queue”)
@SendTo(“out.queue”)
public String receiveQueue(String text) {
System.out.println(”Consumer2收到的報文爲:”+text);
return “return message”+text;
}
}

package com.chhliu.springboot.jms;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;

@Component
public class Consumer2 {

    @JmsListener(destination = "mytest.queue")
    @SendTo("out.queue")
    public String receiveQueue(String text) {
        System.out.println("Consumer2收到的報文爲:"+text);
        return "return message"+text;
    }
}

從上面的代碼可以看出，我們在receiveQueue方法上面多加了一個註解@SendTo(“out.queue”)，該註解的意思是將return回的值，再發送的”out.queue”隊列中，下面我們再來跑一下前面的測試，在監控頁面中，我們發現，”out.queue”隊列中已經有內容了，如下：

進入Browse界面觀看：

最後看下收到的具體信息：

我們發現，該隊列中的消息，就是我們返回的值！

九、對Producer進行改造

通過上面的示例，我們現在對Producer進行改造，使其既能生產報文，又能消費隊列中的報文，代碼如下：

[java] view plain copy

print?

package com.chhliu.springboot.jms;
import javax.jms.Destination;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;
@Service(“producer”)
public class Producer {
@Autowired
private JmsMessagingTemplate jmsTemplate;
public void sendMessage(Destination destination, final String message){
jmsTemplate.convertAndSend(destination, message);
}
@JmsListener(destination=“out.queue”)
public void consumerMessage(String text){
System.out.println(”從out.queue隊列收到的回覆報文爲:”+text);
}
}

package com.chhliu.springboot.jms;

import javax.jms.Destination;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

@Service("producer")
public class Producer {
    @Autowired
    private JmsMessagingTemplate jmsTemplate;

    public void sendMessage(Destination destination, final String message){
        jmsTemplate.convertAndSend(destination, message);
    }

    @JmsListener(destination="out.queue")
    public void consumerMessage(String text){
        System.out.println("從out.queue隊列收到的回覆報文爲:"+text);
    }
}

測試結果如下：

[java] view plain copy

print?

從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!

從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
Consumer收到的報文爲:myname is chhliu!!!
Consumer2收到的報文爲:myname is chhliu!!!
從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
