报错：

Unsatisfied dependency expressed through field 'xxxMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.gdata.biz.content.mapper.xxxMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

提示：

expected at least 1 bean which qualifies as autowire candidate

期望至少有1个bean，可以作为自动装配的候选对象

原因：

没有扫描到mapper包

解决方法：

在主启动类上添加扫描mapper包的注解。

@MapperScan("com.xxx.xxx.xxx.mapper")
