Error creating bean with name 'orderServiceImpl'异常解决

在javaweb开发中,当项目启动时有可能会报“org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'orderServiceImpl'”等异常,如下所示:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'orderServiceImpl': Injection of autowired dependencies failed;
nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private cn.com.tpyyes.order.base.sendinput.dao.
OrderCommonDao cn.com.tpyyes.order.sendinput.dao.impl.OrderEditBatByImagesDaoImpl.orderCommonDao; nested exception is org.springframework.beans.factory.
NoSuchBeanDefinitionException: No qualifying bean of type [cn.com.tpyyes.order.base.sendinput.dao.OrderCommonDao] found for dependency: expected at least 1

解决方案:
当出现类似Error creating bean with name 'orderServiceImpl'这种异常的时候,说明你在orderServiceImpl类里面的@Autowired没有注入成功。
这个时候你就要检查applicationContext.xml文件里面“<context:component-scan base-package=" cn.com.tpyyes.order.service" />”这个包扫描配置,看里面的路径是否正确就可以了。
