2.调用
UserMapper.javaimport java.util.List;import com.offcn.bean.Student;public interface UserMapper { public List<Student> selectStudent(); public void insertStudent(Student student); public void deleteBySid(Integer sid); public Student selectBySid(Integer sid); public void updateStudent(Student student);} 
1.请求

指定扫描的包
请求dao层
mybatis-config.xml文件(这是普通的xml文件但是头部需要独立复制一下)<?xml version=\"1.0\" encoding=\"UTF-8\" ?><!DOCTYPE configuration  PUBLIC \"-//mybatis.org//DTD Config 3.0//EN\"  \"http://mybatis.org/dtd/mybatis-3-config.dtd\"><configuration> <settings>  <!-- 开启懒加载模式 -->  <setting name=\"lazyLoadingEnabled\" value=\"true\"/>  <setting name=\"aggressiveLazyLoading\" value=\"false\"/>    </settings></configuration>
mybatis-config.xml1.开启懒加载模式    作用:懒加载其实就是延时加载，即当对象需要用到的时候再去加载。
properties文件
beans.xml1.扫描包    作用:加载加了注解的类对象2.加载properties文件3.配置数据源    作用:将properties文件中的信息获取4.配置数据源事务管理器    作用:配置数据源5.开启基于注解的事务支持6.加载mybatis全局配置文件7.扫描Mapper接口    作用:连接dao层的
