解决：

解决：没有扫描执行到mapper文件

spring没有找到mapper文件：

spring：application.xml文件中的mapperLocations地址不对，修改正确

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />

<property name="mapperLocations" value="classpath*:mybatis/mapper/**/*_mapper.xml" />

<property name="dataSource" ref="dataSource" />

</bean>
