谷粒商城09-创建公共common的依赖模块

由于上一步生成的代码中, 缺少一些依赖包,而这些依赖包是每个模块都需要的, 因此创建一个公共的依赖模块进行统一的管理

选中父工程 new module

注意第二步是选中Maven 而不是选择 Spring Inialier. 因为公共的模块是不需要启动类的, 只需要管理jar包用的.

接下来填上 gulimall-common 模块名即可  
在pom中进行描述

<parent>
        <artifactId>gulimall</artifactId>
        <groupId>com.atguigu.gulimall</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    
    <artifactId>gulimall-common</artifactId>
    <description> 公共的依赖 ,bean 工具类等  </description>

在每一个业务模块的pom中, 引入common的依赖,

<dependency>
        <groupId>com.atguigu.gulimall</groupId>
        <artifactId>gulimall-common</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>

如果遇到pom中没有自动提示, 在此处点击update

拷贝工具类到common模块中

现在就只有controller的shiro的注解是报错的, 每一个controller都去改的话,太麻烦, 只需要改生成代码的模板即可.  
将生成代码的模板进行注解去除. 和最上面的导入的包注释掉

重新运行生成代码的服务, 将重新生成的controller进行替换即可!
