定義上下文路徑時，未找到帶有URI錯誤的HTTP請求的映射
[英]No mapping found for HTTP request with URI error when context path is defined
問題描述
在每個人都說這是騙子之前，我已經閱讀了有關此錯誤的其他問答，但我沒有嘗試過。 至少在上周的某個時候它一直在工作。 今天，我收到此錯誤。 以下是我的文件：

我加載：
http://localhost:9086/registration/
並得到：
HTTP ERROR 404
Problem accessing /registration/. Reason:
Not Found
Powered by Jetty://
有任何想法嗎？ 我嘗試了各種方法，通讀了一些教程，並在各種站點上嘗試了diff方法。 到目前為止沒有運氣。 在我看來應該可以使用，但是...
更新：
我在一些文件中恢復了以前的狀態（更新了上面的那些文件）。 我發現正在發生以下情況：順便說一下，我正在使用IntelliJ IDEA社區版。 當我在本地構建並運行時
mvn clean compile
該頁面無法加載（未找到映射，上面報告了異常）。
但是，當我直接從Maven項目下運行Lifecycle \\ compile並將Jetty設置為通過Plugins \\ jetty：run運行時，頁面將成功加載。 此外，我可能還需要在IntelliJ中將root \\ src \\ main標記為Sources Root或取消標記，然后再次將其標記為，再次運行Lifecycle \\ compile，然后在啟動Jetty時成功加載頁面。 否則，我會得到映射錯誤。
這告訴我，成功或失敗在某種程度上取決於項目的構建方式，即通過何種工具。 同樣，這似乎暗示了工具狀態依賴性與構建問題本身。 這令人沮喪，並使其成為各種Heisenbug。 這不好。
我還將正在談論的頁面（registration.html）添加到OP中的文件列表中。

在哪里設置上下文路徑？ 例如application.properties？
server.servlet.context-path=/my-context-path
實際上，關於Spring Boot，設置上下文路徑后，要通過HTTP Request訪問應用程序，必須在URL前面加上上下文路徑：
http://localhost:9086/my-context-path/registration
