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;
