Spring与Struts框架整合

Posted 2021-01-23 码上加油站

Spring，负责对象对象创建

Struts， 用Action处理请求

 

Spring与Struts框架整合，

         关键点：让struts框架action对象的创建，交给spring完成！

 

Spring与Hibernate整合：

 

【SSH整合:

                   Spring与Struts

                            关键点： action交给spring创建!

                   Spring与Hibernate

                            关键点： sessionFactory对象交给spring创建！

】

 

步骤：

引入jar文件

         1）引入struts .jar相关文件

         2）spring-core  相关jar文件

         3）spring-web 支持jar包

                   spring-web-3.2.5.RELEASE.jar                            【Spring源码】

struts2-spring-plugin-2.3.4.1.jar      【Struts源码】

 

配置:

         4）配置XML

struts.xml                  【struts路径与action映射配置】

bean.xml               【spring ioc容器配置】

web.xml                    

【核心过滤器： 引入struts功能】

【初始化spring的ioc容器】
