redirect - 条纹 : RedirectResolution; How can I redirect to specific action event?

Question

我的 stripes 应用程序中有一个 Action bean。默认处理程序/方法将显示数据列表，即我所有的 MarketResearch 对象的列表

在我的 JSP 上，我可以单击一个以查看其详细信息，这会将我带到另一个 JSP，该 JSP 具有基于您选择的特定 MarketResearch 对象的预填充表单。

我的操作 bean 上有另一个方法，它映射到 save 提交按钮，它接收修改后的表单中的内容，并将其持久化。在这发生之后，我希望它重定向回表单，而不是列表(默认处理程序)操作，这可能吗？

我的操作如下:

public class MarketResearchAction extends BaseAction
{

    @SpringBean
    ClientService clientService;
    private static final String VIEW = "/jsp/marketResearch.jsp";
    private Client client;
    private Client clientBeforeChanges;


    public Client getClient()
    {
        return client;
    }

    public void setClient(Client client)
    {
        this.client = client;
    }

    @DefaultHandler
    public Resolution viewAll()
    {
        return new ForwardResolution(VIEW);
    }

    public Resolution viewClientMarketResearch()
    {
        if (client.getSector().equals("Education"))
        {
            return new ForwardResolution("/jsp/marketResearchEducation.jsp");
        } else if (client.getSector().equals("Local Government"))
        {
            return new ForwardResolution("/jsp/marketResearchLocalGovernment.jsp");
        } else if (client.getSector().equals("Housing Association"))
        {
            return new ForwardResolution("/jsp/marketResearchHousing.jsp");
        }
        return new ForwardResolution("/jsp/viewClientMarketResearch.jsp");
    }

    public Resolution save()
    {
        clientBeforeChanges = clientService.getClientById(client.getId());
        clientService.persistClient(client);
        getContext().getMessages().add(new SimpleMessage("{0} updated", client.getName()));
        return new RedirectResolution("/MarketResearch.action").flash(this);
    }

    public Client getClientBeforeChanges()
    {
        return clientBeforeChanges;
    }

    public void setClientBeforeChanges(Client clientBeforeChanges)
    {
        this.clientBeforeChanges = clientBeforeChanges;
    }

    public ClientService getClientService()
    {
        return clientService;
    }

    public void setClientService(ClientService clientService)
    {
        this.clientService = clientService;
    }


}

这可能吗？还是我从一个糟糕的角度来处理这种情况，应该重构？

谢谢

是的。您可以将 RedirectResolution 返回到表单 jsp。如果您对参数有困难，如果您在 save() 方法中有它们，您可以这样做:

return new RedirectResolution("/theJsp.jsp")
    .addParameter("one", one)
    .addParameter("two", two)
    .addParameter("three", three)
    .flash(this);

如果您没有传递给表单的参数，则必须以某种方式让它们继续运行。您可以通过表单传递 MarketResearch 对象，这样您就可以将它放在那里。

<stripes:hidden name="marketResearch"  value="${ActionBean.marketResearch}"/> 

并在您的 MarketResearchActionBean 上添加必需的实例变量/getter/setter。
