如何从超链接中捕获Struts中的EventDispatchAction？
我有一个 JSP 页面，其中有多个搜索选项，即“按应用程序 ID 搜索”、“按申请人名称搜索”等。我使用 struts EventDispatchAction 来捕获特定提交按钮生成的事件。这工作正常。下面是 struts-config 文件的快照：
现在我在对搜索结果进行分页时遇到问题，因为单击页码时无法生成事件。它们是超链接。下面是用于生成页码的代码：
<c:forEach items="${pagelist}" var="emp">
<td><a href="#?page=${emp}">${emp}</a></td>
</c:forEach>
我不确定用什么来代替 # 来为 EventDispatchAction 生成事件。下面给出了捕获提交的 ActionClass：
public class SearchApplicationAction extends org.apache.struts.actions.EventDispatchAction {
public ActionForward idSubmit(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
List applist = null;
SearchApplicationForm searchApp = (SearchApplicationForm) form;
String idText = searchApp.getAppId();
int appId = Integer.parseInt(idText);
UserManager manager = new UserManager();
applist = manager.ViewApplicationById(appId);
sess.setAttribute("applicationList", applist);
return mapping.findForward("idSubmit");
}
public ActionForward nameSubmit(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
List applist = null;
SearchApplicationForm searchApp = (SearchApplicationForm) form;
String name = searchApp.getApplicantName();
UserManager manager = new UserManager();
applist = manager.ViewApplicationByName(name);
sess.setAttribute("applicationList", applist);
return mapping.findForward("nameSubmit");
}
}
这方面的任何帮助都会非常有帮助。谢谢
I have a JSP page where there are multiple options for search, i.e. "search by Application id", "search by Applicant name" etc. I have used struts EventDispatchAction to catch the event generated by a particular submit button. This is working fine. Below is the snap of the struts-config file for this:
Now I am facing problem in paginating the search results, because I am not able to generate event when the page numbers are clicked. They are hyperlinks. Below is the code used to generate the page numbers:
<c:forEach items="${pagelist}" var="emp">
<td><a href="#?page=${emp}">${emp}</a></td>
</c:forEach>
I am not sure what to put in place of # to generate event for EventDispatchAction. The ActionClass to capture the submits is given below:
public class SearchApplicationAction extends org.apache.struts.actions.EventDispatchAction {
public ActionForward idSubmit(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
List applist = null;
SearchApplicationForm searchApp = (SearchApplicationForm) form;
String idText = searchApp.getAppId();
int appId = Integer.parseInt(idText);
UserManager manager = new UserManager();
applist = manager.ViewApplicationById(appId);
sess.setAttribute("applicationList", applist);
return mapping.findForward("idSubmit");
}
public ActionForward nameSubmit(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
List applist = null;
SearchApplicationForm searchApp = (SearchApplicationForm) form;
String name = searchApp.getApplicantName();
UserManager manager = new UserManager();
applist = manager.ViewApplicationByName(name);
sess.setAttribute("applicationList", applist);
return mapping.findForward("nameSubmit");
}
}
Any help in this regard will be very helpful. Thanks

谢谢米格尔。实际上，问题不在于使用带有链接的操作，而在于捕获适当的事件。当用户单击任何搜索选项时，该事件将在 SearchApplicationAction 中处理。但是在对搜索结果进行分页之后，只要有人单击页码，我就必须生成这些操作。如果我对超链接中的操作进行硬编码，那么它就可以工作。
Thanks Miguel. Actually the problem is not in using actions with links but to catch the appropriate event. When a user clicks on any of the search options then the event is handled in SearchApplicationAction. But after paginating the search results, I have to generate those actions whenever someone clicks on the page numbers. If I hardcode the action in hyperlink then it works.
您可以使用 struts taglib:
You could use the struts taglib:
<html:link>in order to build links related to struts actions. See this: http://struts.apache.org/1.x/struts-taglib/tagreference.html#html:link
