后台：org.springframework.beans.factory.BeanCreationException: Error creating bean with name '/studentAction' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [com.yourcompany.struts.ibatis.IbatisExuserDAO] to required type [com.yourcompany.struts.dao.StudentDAO] for property 'exuserDAO'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [com.yourcompany.struts.ibatis.IbatisExuserDAO] to required type [com.yourcompany.struts.dao.StudentDAO] for property 'exuserDAO': no matching editors or conversion strategy found
