JavaWeb筆記023 SSM配置文件樣例

配置文件僅供參考，摘取自己需要的即可

運行注意事項：由於工程之間有相互依賴，要把被依賴的安裝到本地倉庫中在運行工程

如果使用dubbo，pojo會進行傳輸，需要序列化，所有的pojo都需要實現Serializable接口

工程結構還是筆記022中的

xx-parent 父工程，所有工程都集成自此工程，定義所有的maven引用的版本，打包方式pom
   |
   |----xx-common通用的工具類和pojo，打包方式jar
   |
   |----xx-maganer服務層父工程，打包方式pom，依賴xx-common
   |        |
   |        |----xx-maganer-pojo打包方式jar，逆向工程生成的類都放在這裏
   |        |----xx-maganer-dao打包方式jar，依賴pojo
   |        |----xx-maganer-interface打包方式jar，依賴pojo
   |        |----xx-maganer-service打包方式war，依賴interface和dao.Spring的dao，service，事務配置文件和mybatis數據庫配置SqlMapConfig.xml、db.properties都放在這裏
   |
   |----xx-maganer-web表現層，打包方式war，依賴xx-common，依賴interface

xx-parent下的三個子工程是平級的，xx-parent和它的三個子工程都是MavenProject，xx-manager的子工程是MavenModule

注意

1.parent項目要install一下，被依賴的module和項目最好逐個安裝一遍，例如A依賴B，B依賴C，按照CBA的順序挨個安裝一遍。
2.Spring配置文件要放到聚合工程中，如項目結構爲：

parent -pom打包
    |- dao -jar打包
    |- service -jar打包
    |- web -war打包
那麼Spring的配置文件應該放到web項目中
