项目环境

1. jdk 1.8
2. spring 2.7.x
3. maven 3.6

项目结构

模块功能

client – 对外service
common – 共用工具切面等
main – 启动类
goods – 子模块具体实现

模块间依赖关系

client – 无依赖
common – 无依赖
main – client、common、goods
goods – client、common

具体POM配置

顶级pom

引入需要被使用的所有项目子模块，并统一制定版本号

main 设置打包入口，扫描的xml配置项等
    main 中dependency中引入顺序需要注意，需要保证，未被依赖的在前，被依赖的子模块在后。因为此处的顺序决定了maven install的顺序

使用maven打包root目录

生成的main jar，及包含了所有模块
