  • JavaWeb_(SpringMVC框架)SpringMVC&Spring&MyBatis整合

      JavaWeb_(SpringMVC框架)测试SpringMVC&Spring&MyBatis三大整合  传送门

    1、整合ssm 3大框架 过程

      a)导包 -> spring_Jar整理 -> ssm框架整合包

      b)配置 -> web.xml

        i.读取spring配置文件;

        ii.配置springmvc前端控制器;

      c)配置 -> applicationContext.xml

        i.读取数据库配置文件;

        ii.配置数据源连接池;

        iii.开启注解扫描;

        iv.配置事务核心管理器;

        v.开启注解事务;

        vi.配置视图解析器;

        vii.配置Mybatis:

          1.配置sqlSessionFactory;

          2.配置别名;

          3.配置mapper工厂;

      

      a)导包 -> spring_Jar整理 -> ssm框架整合包

      

      b)配置 -> web.xml

        i.读取spring配置文件;

        ii.配置springmvc前端控制器;
