这里以图书查询的功能为例子，来进行SSM的整合，从创建数据库，到导入jar包，一步一步的进行整合，直到能跑为止，我也是初学SSM整合，这里只是给出了能跑起来的代码，里面有简单的注释，并没有详细讲解原理，希望能帮到初学SSM整合的朋友，这些东西，可以拷过去直接用。
目录
首先给出整体的架构
创建数据库
导入maven依赖
opjo
dao层
service层
controller层
resource
BookMapper.xml
mybatis-config.xml
database.properties
spring-dao.xml
spring-service.xml
spring-mvc.xml
applicationContext.xml
jsp文件
部署到Tomcat上运行
首先给出整体的架构
这里导出了数据库文件，可以直接使用，这里给出关于数据库的导入和导出问题
