  • struts-2.3+spring-4.0+hibernate-4.0整合项目

    1.加入spring
      1)加入jar包
      2)配置web.xml applicationContext.xml (监听器)
      3)加入spring的配置文件:aop context tx bean

    1.加入hibernate
      1.1建立持久化类,和其对应的xxx,hbm。xml文件,生产对应的数据表
      1.2spring 整合hibernate

    1)加入jar包
      2)类路径下加入hibernate.cfg.xml文件.其中配置hibernate的基本配置
      3)建立持久化类和对应的xxx.hbm。xml
      4)和spring整合
        a)加入c3p0和mysql的驱动
        b)在spring的配置文件中配置:数据源,sessionFactory,声明式事务

      5)启动项目,会看到生产对应的数据表

    3.加入struts2
      1)加入jar包,有重复的包,删除版本低的包
      2)在web。xml文件中配置Struts2的Filter
      3)加入配置文件Struts.xml
      4)整合Spring
        a)加入Struts2的Spring插件的jar包
        b)在Spring的配置文件中正常配置Action,并设置Scope为prototype
        c)在Struts2的配置文件中Action时,class属性指向该Action在IOC中的id

    注:以下代码的首行仅仅起到标记注释作用,开发时请去掉!
