依賴jar包配置
SpringMVC與Spring整合
SpringMVC + Spring整合:
- 拷貝JAR包.
- 修改web.xml文件.
a.配置SpringMVC的核心控制器.
b.配置Web應用啟動時自動創建spring容器.
- 增加SpringMVC的配置文件.
- 增加Spring的配置文件,如果配置文件名不是默認的,還需要在web.xml文件指定Spring文件的路徑.
----------------------經過上面幾步，整合成功-----------------------
接下來的開發很簡單:
Controller開發(但Controller不要主動new Service組件,只要有setter)、配置，與不整合Spring基本一樣.
Service組件配置在Spring容器中.
注意：Controller中需要依賴的Service對象要與Service類的配置ID必須相同.
修改web.xml文件
