        ssm整合步骤：
        第一步：mybatis单独测试
            1.引入mybatis,mysql依赖
            2.创建实体和dao层。注意：dao层只有接口。
            3.创建dao层与之对象的mapper.xml配置文件
            4.创建mybatis的核心配置文件。
            5.通过api执行mybatis
                5.1 获取mybatis核心配置的io流对象
                5.2 创建SqlSessionFactory对象
                5.3 创建sqlSession对象
                5.4 创建dao层的代理对象。

       第二步： mybatis和spring进行整合
            整合的思想：使用spring的ioc的思想来管理mybatis中的对象。
            1.引入spring的ioc相关的依赖，还需要引入 spring和mybatis整合的工具包(依赖版本是1.3.0)   mybatis-spring
                还要包含 阿里巴巴的连接池，spring-jdbc,
            2.创建spring的配置文件，
            3.在spring的配置中创建SqlSessionFactory对象。创建数据源对象
            4.在mybatis中删除数据源相关的配置。
            5.采用包扫描的方式创建mapper对象

      第三步：单独测试springMVC
            1.引入springMVC的依赖  spring-webmvc
            2.在web.xml中配置前端控制器DispatcherServlet
               配置乱码过滤器
            3.创建springMVC.xml配置，配置注解扫描，注解驱动，视图解析器
            4.编写controller

      第四步：spring和springmvc整合
            整合的要点：就是让springmvc从servletContext中获取spring容器即可
            1.在web.xml中配置spring的监听器即可。

       思考一个问题：
