hibernate+sping 配置文件的问题(分不够再加)
在调试的时候,出现如下提示:

org.springframework.beans.factory.BeanCreationException:   Error   creating   bean   with   name   'userService '   defined   in   ServletContext   resource   [/WEB-INF/applicationContext.xml]:  

Can 't   resolve   reference   to   bean   'userTarget '   while   setting   property   'target ';   nested   exception   is   org.springframework.beans.factory.BeanCreationException:   Error   creating   bean   with   name   'userTarget '   defined   in   ServletContext   resource   [/WEB-INF/applicationContext.xml]:
