基于SpringBoot中activeMq的JmsTemplate的实例

SpringBoot 中使用activeMq的步骤：

1、pom中引入jar包：

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

2、spring boot配置文件中配置activeMq

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.user=admin
spring.activemq.password=admin
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false

3、Application 中添加对应的bean生成规则

package com.telligen.ascertain;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.jms.core.JmsTemplate;
import javax.jms.ConnectionFactory;

@SpringBootApplication
public class ApproveApplication {

public static void main(String[] args) {
SpringApplication.run(ApproveApplication.class, args);
}

@Bean
public ConnectionFactory connectionFactory(){
System.out.println("aaaaaaaaaaaaaaaaaaaaaa");
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
connectionFactory.setBrokerURL("tcp://localhost:61616");
connectionFactory.setUserName("admin");
connectionFactory.setPassword("admin");
return connectionFactory;
}
@Bean
public JmsTemplate genJmsTemplate(){
System.out.println("aaaaaaaaaaaaaaaaaaaaaabbbbbbbbb");
return new JmsTemplate(connectionFactory());
}
@Bean
public JmsMessagingTemplate jmsMessageTemplate(){
System.out.println("ccccccccccccc");
return new JmsMessagingTemplate(connectionFactory());
}

}

4、发送消息

package com.telligen.ascertain.approve.common.util.network;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Component;

@Component
@Scope("singleton")
public class ActiveMqUtil   {
   private Logger logger = Logger.getLogger(ActiveMqUtil.class);

@Autowired
   private JmsMessagingTemplate jmsMessagingTemplate;

public void sendMsg(String destinationName ,String message){
       logger.info("发送 消息到消息队列");
       jmsMessagingTemplate.convertAndSend(destinationName,message);
   }
}

遇到的问题：

jmsMessagingTemplate 注入不成功，spring初始化错误，异常如下，只要按照步骤三就可以了：

Springboot整合activemq时报jmsMessagingTemplate未加载错误

错误现象

Bean method ‘jmsMessagingTemplate' in ‘JmsAutoConfiguration.MessagingTemplateConfiguration' not loaded because Ancestor org.springframework.boot.autoconfigure.jms.JmsAutoConfiguration did not match

网上解决方案

网上最多的方案是：application.properties中配置项的行尾有空格。检查没有，排除了这种可能。

第二种解决方案是：按如下方式将配置spring.activemq.pool.enabled改为false

spring.activemq.pool.enabled=false

启动springboot是不报错了，但是要发的消息也没进队列。至于为什么就不报错了，还没搞明白。如有高人请指点一二。

解决方案

查看ActiveMQConnectionFactoryConfiguration类,自动配置发现需要引入下面这个依赖：

<dependency>
       <groupId>org.messaginghub</groupId>
       <artifactId>pooled-jms</artifactId>
       <version>1.0.3</version>
</dependency>

将依赖引入pom，再启动springboot，搞定！
