配置文件application.yml
spring:
rabbitmq:

RabbitMQ教程
以下教程都可以在RabbitMQ在github的仓库rabbitmq-tutorial中找到，具体springboot在spring-amqp模块中。在这里面要讲一下如何运行相关代码
### 打包项目
mvn clean package
### 运行项目
java -jar xxx.jar --spring.profiles.active=tut1,sender
### 下面放上相关运行命令
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=hello-world,receiver");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=hello-world,sender");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=work-queues,receiver");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=work-queues,sender");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=pub-sub,receiver");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=pub-sub,sender");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=routing,receiver");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=routing,sender");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=topics,receiver");
System.out.println("java -jar rabbit-tutorials.jar --spring.profiles.active=topics,sender");
#### 注意，该项目使用了定时任务
你需要配置允许定时调度的注解
