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:61616spring.activemq.user=adminspring.activemq.password=adminspring.activemq.in-memory=truespring.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; @SpringBootApplicationpublic class ApproveApplication { public static void main(String[] args) {SpringApplication.run(ApproveApplication.class, args);} @Beanpublic ConnectionFactory connectionFactory(){System.out.println("aaaaaaaaaaaaaaaaaaaaaa");ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();connectionFactory.setBrokerURL("tcp://localhost:61616");connectionFactory.setUserName("admin");connectionFactory.setPassword("admin");return connectionFactory;}@Beanpublic JmsTemplate genJmsTemplate(){System.out.println("aaaaaaaaaaaaaaaaaaaaaabbbbbbbbb");return new JmsTemplate(connectionFactory());}@Beanpublic 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！
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
