Answer 1

studentAction中的addservice的实体类型和要被注入的实体类型不同.........Cannot resolve reference to bean 'addservice' while setting bean property 'as'...

Answer 2

Error creating bean with name 'studentAction' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'addservice' while setting bean property 'as'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'addservice' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: 
看看配制文件。

Answer 3

1，看看你的实体类和配置文件有没有类型错误问题2，看看Struts配置文件中action的type是不是改成了org.springframework.web.struts.DelegatingActionProxy3，看看Spring配置文件中注入是否有错。一般都是这些问题，不是你再贴配置文件出来大家看看

Answer 7

请问Demo.Service.AddStudent类里面的setter和getter方法是怎么写的？

Answer 8

addservice  这个bean  里面
sd 这个属性对应的类不对 
看下 bean 要求的是什么类 你传进去的又是什么类
