通过 Togglz 管理控制台编辑功能时出现错误 404

Question

我在带有 Spring 4.0.5.RELEASE 和 Jetty 9.2.1.v20140609.

的 Web 应用程序中使用 Togglz 2.0.1.Final

当我尝试使用 Togglz 管理控制台编辑功能时，POST 请求收到 404 状态代码。

请求Headers

请注意，异常会抱怨地址 (http://my-host/my-app/) different from the called one (http://my-host/my-app/togglz/edit)，就好像重定向或转发已到位。

分析 Togglz 源代码，特别是 EditPageHandler class，当 POST 成功时确实有一个 sendRedirect() 调用，但它应该以返回 302 状态代码并重定向到 /togglz/index URI.

我无法找到 404 可能发生的位置，而且我无法调试它，因为该问题只发生在生产环境中（在开发环境中它很好，而且我已经检查 Jetty 版本，它们是相同的）。

有人知道这件事吗？

提前致谢。

Answer 1

经过一番努力，我找到了问题的原因！

Togglz 无法写入功能所在的 .properties 文件（缺少权限）。

现在，不要问我为什么 FeatureConsoleServlet 没有记录原始异常以及为什么它会导致转发到根 URI。（如果有人对此有答案，请随时编辑此答案）。
