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

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。
