Action:Consider revisiting the entries above or defining a bean of type ‘org.springframework.jms.core.JmsMessagingTemplate’ in your configuration.
原因总结有以下3点原因：
1.spring.activemq.pool.enabled=true，线程池开启，后面有空格，且没有引入线程池包
<dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-pool</artifactId> </dependency>
2.springboot版本问题不支持，建议用2.0版本启动
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent>
猜想：估计是因为2.1.0+版本有自己的线程池管理，导致冲突
3.spring.activemq.pool.enabled=false,关闭线程池
springboot整合activemq踩过坑
启动时候就关闭了
配置如下
server: port: 8762# context-path: /memebereureka: client: service-url: defaultZone: http://localhost:8761/eureka/spring: application: name: member redis: host: 127.0.0.1 password: 123456 port: 6379 pool: max-idle: 100 min-idle: 1 max-active: 1000 max-wait: -1 datasource: name: test1 url: jdbc:mysql://127.0.0.1:3306/dandan-member username: root password: 123456 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 ##activemq连接信息activemq: broker-url: tcp://localhost:61616 in-memory: true pool: enabled: false##队列messages: queue: messages_queue
解决如下
原本activemq 没有在spring.后面直接在前面了，与spring同级了
解决后配置如下
server: port: 8762# context-path: /memebereureka: client: service-url: defaultZone: http://localhost:8761/eureka/spring: application: name: member redis: host: 127.0.0.1 password: 123456 port: 6379 pool: max-idle: 100 min-idle: 1 max-active: 1000 max-wait: -1 datasource: name: test1 url: jdbc:mysql://127.0.0.1:3306/dandan-member username: root password: 123456 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 ##activemq连接信息 activemq: broker-url: tcp://localhost:61616 in-memory: true pool: enabled: false##队列messages: queue: messages_queue
建议。yml缩进要四个字节。一个字节不容易分辨
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。
但我们好多人没想过，勇敢的冷静的理智的去接受失败，
