基于SpringBoot中activeMq的JmsTemplate的实例基于SpringBoot中activeMq的JmsTemp

SpringBoot 中使用activeMq的步骤： 1、pom中引入jar包：

org.springframework.bootspring-boot-starter-weborg.springframework.bootspring-boot-starter-activemqorg.apache.activemqactivemq-pool

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); } @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); @Autowiredprivate 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
