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;

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。
