<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=false3、Application 中添加對應的bean生成規則

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、發送消息

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('發送 消息到消息隊列');jmsMessagingTemplate.convertAndSend(destinationName,message); }}

遇到的問題：

jmsMessagingTemplate 注入不成功，spring初始化錯誤，異常如下，只要按照步驟三就可以了：

錯誤現象

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

網上解決方案

網上最多的方案是：application.properties中配置項的行尾有空格。檢查沒有，排除了這種可能。

第二種解決方案是：按如下方式將配置spring.activemq.pool.enabled改為false

spring.activemq.pool.enabled=false

啟動springboot是不報錯了，但是要發的消息也沒進隊列。至于為什么就不報錯了，還沒搞明白。如有高人請指點一二。

查看ActiveMQConnectionFactoryConfiguration類,自動配置發現需要引入下面這個依賴：

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

將依賴引入pom，再啟動springboot，搞定！

以上為個人經驗，希望能給大家一個參考，也希望大家多多支持好吧啦網。
