springCloud 架构中怎么规避同一个类Bean在多个子应用中重复使用

多模块相互引用时，可能pom.xml报红，可以用如下命令,表示将模块打成本地jar引用，就是把jar 安装到本地。

mvn -Dmaven.test.skip=true -U clean install
 

product的pom.xml

<artifactId>product</artifactId>
	<version>0.0.1-SNAPSHOT</version>
    <modules>
        <module>common</module>
        <module>server</module>
        <module>client</module>
    </modules>
    <packaging>pom</packaging>

		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.0.M3</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <product-common.version>0.0.1-SNAPSHOT</product-common.version>
	</properties>

            <dependency>

common的pom.xml

<parent>
        <artifactId>product</artifactId>
        <groupId>com.imooc</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>product-common</artifactId>

client的pom.xml

client引入了product-common

 <parent>
        <artifactId>product</artifactId>
        <groupId>com.imooc</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>product-client</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-netflix-core</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
        </dependency>

        <dependency>
            <groupId>com.imooc</groupId>
            <artifactId>product-common</artifactId>
        </dependency>
    </dependencies>

server的pom.xml

也用到了引入了product-common

<parent>
        <artifactId>product</artifactId>
