建立父项目——HelloMQ

配置父项目pom

<?xml version="1.0" encoding="UTF-8"?>

    org.example
    HelloMQ
    pom
    1.0-SNAPSHOT
    
        publisher

                org.springframework.cloud
                spring-cloud-dependencies
                Hoxton.SR1
                pom
                import
            
            
            
                com.alibaba.cloud
                spring-cloud-alibaba-dependencies
                2.2.5.RELEASE
                pom
                import
            
            
            
                mysql
                mysql-connector-java
                8.0.16
            

            
            
                com.alibaba

                1.2.4
            
            
            
                com.baomidou
                mybatis-plus-boot-starter
                3.4.1

配置子项目依赖

版本不需要配置，从父项目中继承
