看異常棧需要抓重點(diǎn)，
那么你的錯(cuò)誤重點(diǎn)在于最后一句

: Could not resolve type alias 'Admin'. Cause: java.lang.ClassNotFoundException: Cannot find class: Admin

應(yīng)該是你的mapper使用了 Admin 而不是包名+Admin
解決方案 兩種
1、
將AdminDaoImpl.xml 中所有的Admin改成包名+Admin
2、
新建mybatis-config.xml
配置別名

<configuration>  
  <typeAliases>  
      <typeAlias type="包名.Admin" alias="Admin"/>  
  </typeAliases>  
</configuration>  

在spring-mybatis.xml 引入mybatis配置

     <!-- 配置mybatis的sqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 自動(dòng)掃描mapper.xml文件-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        <!-- 載入mybatis全局配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

最后，編碼不易 望采納。
