struts2转发到不同页面
我有 view.jsp 和 edit.jsp 页面。两者都调用操作的 load() 方法，该方法返回 SUCCESS。有没有办法转发到来自struts.xml 的页面请求，而不是这个？
<action name="call_1" method="load" class="package.action.List">
<result name="success" type="json">/WEB-INF/view.jsp</result>
</action>
<action name="call_2" method="load" class="package.action.List">
<result name="success" type="json">/WEB-INF/edit.jsp</result>
</action>
另外，我的操作将哈希图构建为 {"3":"adam","1":"brian","2":"brit","4":"den"}，用于填充下拉菜单。它是根据值排序的，但由于某种原因 json 仍然按以下顺序显示它。 布莱恩->布里特->亚当->登。当键是字符串时，为什么仍然根据键排序。
I have view.jsp and edit.jsp pages. Both call load() method of an action, which returns SUCCESS. Is there a way to forward to the page request came from in struts.xml, instead of this?
<action name="call_1" method="load" class="package.action.List">
<result name="success" type="json">/WEB-INF/view.jsp</result>
</action>
<action name="call_2" method="load" class="package.action.List">
<result name="success" type="json">/WEB-INF/edit.jsp</result>
</action>
Also, my action builds hashmap as {"3":"adam","1":"brian","2":"brit","4":"den"}, which is used to populate a drop down menu. It is sorted based on values, but for some reason json still dispaly it in the following order.
brian->brit->adam->den. Why is still being sorted based on keys when keys are strings.

是的，您可以使用 通配符映射 来压缩您的两个 < code>定义合二为一。
上面的代码将获取操作请求 URL 中连字符后面的部分，并使用它设置结果位置。然后，您可以使用这两个 URL 之一来调用它：

Yes, you can use wildcard mappings to condense your two
<action>definitions into one.The above will take the part after the hyphen in the action request URL and use it set the result location. You could then call it with either of these two URLs:
