@Autowired

private UserDaouserDao;

注入UserDao时，报错：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.ischoolbar.programmer.dao.UserDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

原因：spring里没有注入

在applicationContext.xml里加上：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

    <property name="basePackage" value="com.ischoolbar.programmer.dao"/>

</bean>
