java - struts2.0中HTTP 404未找到错误。但控制台没有显示任何错误

Question

我正在尝试在 struts 中创建动态 Web 应用程序，但 Web 浏览器中显示以下错误

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

通常这个错误是由于缺少库或页面而出现的，我会通过控制台来诊断它们。但这一次控制台没有显示任何类型的错误。

这是控制台输出:

错误:

我尝试了类似问题给出的解决方案，但没有结果。

Answer 1

您不应该不要直接访问 JSP 页面，而且它们存储在 WEB-INF 下，浏览器无法访问。

解决方案是创建一个名为 WEB-INF/content 的文件夹并将文件放在那里，然后使用 convention plugin创建操作映射和结果配置。此文件夹名称由 Struts 搜索资源以获取结果的约定使用。

约定插件允许直接访问WEB-INF下的页面，但您可以通过Deny direct access to JSP files in Struts2 with Naming Convention plugin来阻止这种情况.

<小时/>

另一个point是这样的:

Convention plugin creates configuration from all JSPs there. So if you have do-something.jsp under result path you can use /do-something in the browser to return this actionless result.
