点击了退出系统后，网页变空白，struts-config.xml文件中配置如下：
<action path="/logout" type="action.logoutAction">
<forward name="Logout" path="/login.jsp"/>
</action>
Action文件logoutAction.java如下：
package action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class logoutAction extends Action {
public ActionForward execute(ActionMapping mapping,HttpServletRequest request,HttpServletResponse response){
HttpSession session=request.getSession();
session.invalidate();
return mapping.findForward("Logout");
}
}
在Action中设置断点证明并没有能够进入logoutAction，MyEclipse1.2也并没有报错信息，请问如何解决。谢谢~~ |
