[Spring Boot] Spring Boot integrates RabbitMQ

[Spring Boot] Spring Boot integrates RabbitMQ​

1. Sending and receiving messages​

Spring Boot provides the spring-boot-starter- amqp component, which can be seamlessly integrated with Spring Boot by simply configuring it. The following example demonstrates integrating RabbitMQ to receive and send messages.

Step 01 Configure pom package.​

Create a Spring Boot project and add spring-bootstarter-amqp and other related component dependencies in the pom.xml file:

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

In the above example, the amqp component spring-bootstarter-amqp that comes with Spring Boot is introduced.

Step 02 Modify the configuration file.​

Modify the application.properties configuration file and configure the host address, port and account information of rabbitmq.

    
      2. spring.rabbitmq.port=5672
    
      3. spring.rabbitmq.username=quest
    
      4. spring.rabbitmq.password=quest
    
      5. spring.rabbitmq.virtualHost=order

In the above example, the address of the RabbitMQ service is mainly configured. RabbitMQ configuration is controlled by spring.rabbitmq.* configuration properties. The virtual-host configuration item specifies the virtual host created by the RabbitMQ service, but this configuration item is not required.
