1. 本身的理解
html
spirngmvc有本身的容器,Spring 也有本身的IOC容器,在整合的時候如何處理呢?java
在網上查了資料,能夠知道,SpringMVC 主要的做用是攔截客戶端的請求,以後交給Controller, Controller再調用service層; 這樣,咱們在整合的時候就能夠這樣來處理了:web
SpringMVC IOC 容器和 Spring IOC 容器有什麼管理呢?spring
2. 具體步驟:express
引用的jar包:基本和Spring的架構包不變,主要添加了spring 源碼中沒有的jar包:commons-logging 和 standardspring-mvc
web.xml 文件架構
