Spring整合MyBatis 你get了吗?

                Spring整合MyBatis                                                   

1.整体架构
dao,entity,service,servlet,xml

2..引入依赖

3.MyBatis配置文件
  配置个typeAliases  配置entity,是的访问entity包下的类可以不使用全路径。小配置中
4.xml
  1.编写数据源
  2.创建 SqlSessionFactoryBean 节点
    2.1连接数据源
    2.2写入MyBatis的配置文件(加一个classPath:)
  3.创建MapperScannerConfguln 节点
    3.1配置basePackage ref是dao文件夹全路径
  4.配置service节点
    4.1传入dao层接口(注意命名规范,接口要用I开头,方便识别)

5.编写web.xml
  5.1编写上下文
  5.2编写监听器
  5.3编写servlet web.xml的方式

6.编写servlet
  6.1编写添加图书的逻辑代码。
