解决spring mybatis 整合后mapper接口注入失败
spring整合mybatis，在dao层我们只写一个接口，配置相应的*mapper.xml文件，
报如下错误：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'helloController': Unsatisfied dependency expressed through field 'helloService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'helloService': Unsatisfied dependency expressed through field 'helloMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.aopeng.quest.dao.IHelloMapper' available: expected at least 1 bean which qualifies as autowire candidate.

起始这是由于一个低级错误引起的，在applicationContext.xml中有如下的配置：
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.xxx.xxx.dao.**.*" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
basePackage的value应该是指定包名，而我指定的文件名。
改成如下配置，编译正常通过：
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.xxx.xxx.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
