学习 spring-cloud-aibaba附带篇，项目拆分为多模块

把user-center项目拆分成三个模块

• user-server：主要代码逻辑
• user-client：对外接口
• user-common：存放公共java bean

1.项目整体效果

新建目录的时候，记得把java包转成Sources Root，把resources目录转成Resources Root

2 pom.xml 的改造

2.1 user.pom.xml

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.6.RELEASE
    

    com.zc
    user
    0.0.1-SNAPSHOT

    user

    pom

    
        client
        server
        common

                org.springframework.cloud
                spring-cloud-dependencies
                ${spring-cloud.version}
                pom
                import
            

            
                org.springframework.cloud
                spring-cloud-alibaba-dependencies
                ${spring-cloud-alibaba.version}
                pom
                import
            

            
                com.zc
                user-client
                ${user-client.version}
            

            
                com.zc
                user-common
                ${user-common.version}

            org.projectlombok
            lombok
            true
        

        
        
            org.springframework.boot
            spring-boot-starter-data-redis
        

        
        
            com.zc
            user-client
        
        
            com.zc
            user-common
        

    

    
        
            
                org.springframework.boot

    user-client

    
        
            com.zc
            user-common
        
    
    

3.编译和install项目

ctrl+F9 编译项目，install -DskipTests 。这样其它项目就可以依赖user-client了
