现在，当结果'成功'呈现时，它将重定向到文件夹'content'中存在的名为'index.jsp'的页面，即层次结构路径'WEB-INF / content / index.jsp'

我的问题是 如果在结果的location属性中未提及它，则如何将其重定向到内容文件夹中的页面？

当我让项目在调试模式下运行时，我开始了解content / index.jsp。我搜索了整个项目，但我无法找到“内容”的痕迹..

Answer 1

WAR项目包含struts2-convention-plugin-2.3.14.2.jar插件

此插件允许您使用convention来消除XML配置。为此，JSP页面必须放在WEB-INF/文件夹中。

这就是struts.xml和showcase.xml没有定义动作映射的原因。

有关详细信息，请参阅http://struts.apache.org/release/2.3.x/docs/convention-plugin.html

您可以阅读：

By default, the Convention plugin assumes that all of the results are stored in WEB-INF/content. This can be changed by setting the property struts.convention.result.path in the Struts properties file to the new location.
