模塊的實現(xiàn)寫的差不多了，可是 每個頁面的活動都要一個Action，3個對象的增刪改查 就有14個Action。終于今天組長發(fā)飆了，要改成DispatchAction。現(xiàn)上網(wǎng)查查怎么用。。找到個本博客中的文章放入收藏了。

把增刪改查都放到一個Action中，然后在XML中為每個方法配一個
< action
attribute = "addUserForm"
input = "/addUser.jsp"
name = "addUserForm"
parameter="method"
path = "/addUser"
scope = "request"
type="com.why.struts.action.UserAction" >
</ action >
其實如果使用的Form（name=“xxxForm”）是一樣的話，幾個方法配一個<action>也行。用多個的時候，注意path不要寫成一樣的了。
注意parameter的值，作為JSP跳轉(zhuǎn)的do的參數(shù)就可以了。基本上配置方面 和一般<action>區(qū)別就是含有同一個type地址和parameter
<html:link href="addUser.do?method=addUser">Add User</html:link>
參數(shù)值為Action里的方法名，如這個 對應(yīng)為 Action中的
addUser (ActionMapping mapping,ActionForm form, HttpServletRequest request,HttpServletResponse response）
execute就不用在寫了。雖然不知道寫了會怎么樣。
下面是我自己的struts-config.xml配置：
實現(xiàn)offer的增，刪，改，查。其中查和刪的配置寫在了一起。所以是 3個Action，注意其 path，type ，和parameter屬性。調(diào)用時用parameter的值區(qū)分。這里還可以看到定向到offerSearch的URL的使用。
這里的name雖然相同，但是分開的原因是 我需要input這個屬性作為異常的轉(zhuǎn)回頁面。查詢和刪除都不用name 而且異常提示頁面相同，所以合并。
<action
input="/service/offerSearch.jsp"
parameter="operation"
path="/offer"
scope="request"
type="com.neusoft.struts.service.action.OfferAction">
<forward name="success" path="/offer.do?operation=offerSearch&offername="/>
<forward name="show" path="/service/offerSearch.jsp" />
</action>
<action
attribute="OfferForm"
input="/service/offerNew.jsp"
parameter="operation"
name="OfferForm"
path="/offerAdd"
scope="request"
type="com.neusoft.struts.service.action.OfferAction">
<forward name="success" path="/offer.do?operation=offerSearch&offername="/>
</action>
<action
attribute="OfferForm"
name="OfferForm"
parameter="operation"
path="/offerUpdate"
input="/service/offerUpdate.jsp"
scope="request"
type ="com.neusoft.struts.service.action.OfferAction" >
<forward name="success" path="/offer.do?operation=offerSearch&offername="/>
</action>
對應(yīng)的DispatchAction ：
public class OfferAction extends DispatchAction {
public ActionForward offerSearch(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
String offername = changeStr(request.getParameter("offername"));
request.setAttribute("offername", offername);
HttpSession session = request.getSession();
IPageList pageList;
if(request.getParameter("page")==null){ //來自查詢表單的請求
pageList = new PageList(1,OfferManager.getInstance().getOfferList(offername));
session.setAttribute("list", pageList.getResultList());
request.setAttribute("pageList", pageList);
}
else{ //來自分頁鏈接的請求
int page = Integer.parseInt(request.getParameter("page"));
pageList = new PageList(page,OfferManager.getInstance().getOfferList(offername));
session.setAttribute("list", pageList.getResultList());
request.setAttribute("pageList", pageList);
}
return mapping.findForward("show");
}
public ActionForward offerAdd(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
OfferForm offer = (OfferForm) form;
OfferManager.getInstance().addOffer(offer);
return mapping.findForward("success");
}
public ActionForward offerUpdate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
OfferForm offer = (OfferForm) form;
OfferManager.getInstance().offerUpdate(offer);
return mapping.findForward("success");
}
public ActionForward offerDelete(ActionMapping mapping,ActionForm Form,
HttpServletRequest request,HttpServletResponse response)throws Exception{
String id = request.getParameter("offerId");
if(id!=null){
OfferManager.getInstance().offerDelete(Integer.parseInt(id));
}
return mapping.findForward("success");
}
}
