Answer 1

struts-config.xml 各个问题我知道怎么回事儿了,可是改好了以后没错误了,就是提交以后到add.do以后没反应了。也没报错误,貌似是没有转向
<forward name="success" path="/success.jsp"/>
<forward name="failure" path="/failure.jsp"/><?xml version="1.0" encoding="UTF-8"?>

Answer 2

public ActionForward register(ActionMapping mapping,ActionForm form,HttpServletRequestrequest,HttpServletResponse response)改成public ActionForward execute(ActionMapping mapping, ActionForm form,
                             HttpServletRequest request, HttpServletResponse response)
