eclipse启动没问题，打成war包，放在tomcat中直接启动就报这个错。严重: Context initialization failed

解决方案
用SSH做web开发的经常遇到以下问题：
org.springframework.beans.TypeMismatchException: Failed to convert property value of type [com.kgjia.admin.service.impl.ShopTypeServiceImpl$$EnhancerByCGLIB$$6af677d9] to required type [com.kgjia.admin.service.IShopTypeServi......
