Spring Boot ActiveMQ

1.引入依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2. 配置文件

spring.application.name=springboot-rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.publisher-confirms=true
spring.rabbitmq.virtual-host=/

3. 配置类
