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

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
|
1
|
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：
|
1
2
3
4
5
|
<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服务器之家。
