因为ActionSupport是你整合了Spring之后用的败模，再Spring的包里，光用Struts2的话，Action是不用继续任何东西的，不过一般都会有一个baseaction，让你的action都去继承这个东西，里面带了点你比较常用的对象public class BaseAction implements Serializable,RequestAware,SessionAware,ApplicationAware,ServletRequestAware,ServletResponseAware,ServletContextAware{private static final long serialVersionUID = -8737956568774373323L;protected Map request;protected Map session;protected Map application;protected HttpServletRequest httpServletRequest;protected HttpServletResponse httpServletResponse;protected HttpSession httpSession;protected ServletContext httpApplication;public void setSession(Map session) {this.session = session;}public void setRequest(Map request) {this.request = request;}public void setApplication(Map application) {this.application = application;}public void setServletRequest(HttpServletRequest httpServletRequest) {this.httpServletRequest = httpServletRequest;this.httpSession = httpServletRequest.getSession();}public void setServletResponse(HttpServletResponse httpServletResponse) {this.httpServletResponse = httpServletResponse;}public void setServletContext(ServletContext servletContext) {this.httpApplication = servletContext;}public String execute() throws Exception{return "success";}}追问：但是，我查到ActionSupport的源码包是X-WORK里面的，按正常情况我可以调用的吧。另外我之前都可以直接导猜枯羡入的，只是不懂昨晚为什么就不行了追答：你用的x-work整合的啊，那个不熟，穗拍你用的myeclipse的话，按ctrl+shift+o可以控制在多个包的情况下，选择包的导入吧
