本文介绍了一种在Struts框架中实现一个表单对应多个Action的方法，通过使用隐藏变量传递不同Action的信息，并展示了如何配置struts-config.xml及编写对应的Action类。

关于一个Form对应多个Action
背景：修改的页面有修改，新增两个功能。都得需要提交这个表单。
解决：例子，分页参数的传递，使用了隐藏变量

jsp
<html:submit property="action"><bean:message key="button.select"/></html:submit>
<html:submit property="action"><bean:message key="button.prePage"/></html:submit>
<html:submit property="action"><bean:message key="button.nextPage"/></html:submit>

struts-config.xml
<action path="/showHolidayIndex"
    name="HolidayFormBean"
    validate="false"
    input="/pages/holiday/holiday_index.jsp"
    attribute="HolidayFormBean"
    type="com.mgs.MGSkentai.action.holiday.HolidayAction"
    parameter="action"
    scope="request">
    <forward name="showdata" path="/pages/holiday/holiday_index.jsp"></forward>
  </action>

Action

public class HolidayAction extends LookupDispatchAction {

//page
private static int MAX_RECORD = 10;
private int begin = 0;
private int end = 0;

protected Map getKeyMethodMap() {
  Map map = new HashMap();
  map.put("button.select", "BeginSearch");
  map.put("button.prePage", "PrePage");
  map.put("button.nextPage", "NextPage");
  return map;
}

public ActionForward BeginSearch(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {

return mapping.findForward("showdata");
}

public ActionForward PrePage(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) throws Exception {

  return mapping.findForward("showdata");
}

public ActionForward NextPage(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) throws Exception {

  return mapping.findForward("showdata");
}

}

PS: 有更好的方法的话~欢迎大家给意见~谢谢~
