JavaWeb框架————Spring整合三大框架（四）

1、三大框架整合原理

2、整合详解
2.1 导包



2.2 单独配置Spring容器（配置过程中切记配一步测一步即服务器重启测试是否报错）
applicationContext.xml（src目录下）

web.xml（WEB-INF目录下）

2.3单独配置Struts2
struts.xml（src目录下）

2.4 Spring和Struts2整合
Struts.xml（src目录下）

2.5 单独配置Hibernate

hibernate.cfg.xml

2.6 Spring整合c3p0连接池取代hibernate中的连接

2.7 Spring整合hibernate环境操作数据库

2.8 配置Spring的AOP事务

2.8 扩大session的作用范围
