2.2 创建 common 子模块

模块名

<artifactId>gmall-common</artifactId>

给 common 子模块添加依赖

<dependencies>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpmime</artifactId>
    </dependency>
</dependencies>

说明:

• 这个模块内放一些通用代码. 以后用到其他依赖再添加
