问题描述
- maven 项目中修改项目的包名后重新启动报错
-
原来项目运行时正常的，后来把com.fh.controller.information.picture.PictureController
和com.fh.service.information.picture.PictureService修改为com.fh.controller.information.PictureController
和com.fh.service.information.PictureService后出错启动项目报错如下错误

解决方案
ApplicationContext.xml这个配置中定义了一个picturesService的bean，class与原来不对应了，com.fh.service.information.pictures.PicturesService这个应该是错的
需要改成com.fh.controller.information.PictureController
解决方案二：
找了半天 终于找到原因了 原来是maven生成的class文件中还存在原来的class文件，只要吧webapp下的web-inf下面的class文件去掉就好了
