将Java对象从一个Struts动作传递到另一个 [英] Passing a Java object from one Struts action to another

问题描述

在我的一项Struts动作中，我在方法中获得了以下代码：

In one of my Struts action I've got the following code in a method:

  ...
  List<Object> retrievedListOfObjects = c.getListOfObjects();
  return mapping.findForward("view");
}

fw_view 导致具有另一个Struts表单的新Struts动作。假设此表单具有以下字段

fw_view leads to a new Struts action with another Struts form. Let's say this form has got among others the following field

List<Object> listOfObjects;

我现在要传递 retrievedListOfObjects

是否可以将其存储在会话中？

Is this possible without storing it in the session?

推荐答案

您可以将其存储为请求属性。

you can store it as a request attribute.

request.setAttribute("listOfObjects", listOfObjects);

，然后在操作中将其转发给

and then in the Action that is forwarded to

List<Object> listOfObjects = (List<Object>)request.getAttribute("listOfObjects");

鉴于设置请求属性时可以给它们赋予有意义的名称，应该考虑设置许多属性而不是设置一个大对象列表。

Given that when setting request attributes you can give them meaningful names, you should consider setting many attributes rather than setting one big list of objects.
