具体异常如下：org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.nylzh.dao.SysAclModuleMapper’ available，
我的TestController：
//这个地方报了异常
SysAclModuleMapper moduleMapper = ApplicationContextHelper.popBean(SysAclModuleMapper.class);
SysAclModule module = moduleMapper.selectByPrimaryKey(1);
我的applicationContext.xml配置文件
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.nylzh.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
我的dao里面也有相应的类。
请老师帮我看看这是什么问题，我已经找了两天了，谢谢老师
