啟動SpringBoot專案轉換為Jar時子容器失敗

2022-05-28 09:36:05 移動端開發

我又帶著我的一個問題回來了。

我開發了一個 SpringBoot 應用程式，但現在出現了一些錯誤。當我使用 Eclipse 啟動應用程式時，我沒有任何錯誤。但是當我將它轉換為一個可運行的 jar 檔案并啟動它時，我遇到了這些錯誤：我不明白為什么它可以使用 eclipse 而不是 jar 檔案。

:: Spring Boot ::(v2.6.7)

我已經嘗試通過添加來解決這個問題

TomcatURLStreamHandlerFactory.disable();

問題就這樣解決了，但是當我想在瀏覽器中對 localhost:8080 發出 api 請求時，我在控制臺中有這個

2022-05-19 09:29:03.166  INFO 972 --- [nio-8080-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/]       : Initializing Spring DispatcherServlet 'dispatcherServlet'
2022-05-19 09:29:03.195  INFO 972 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : Initializing Servlet 'dispatcherServlet'
2022-05-19 09:29:03.212  INFO 972 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : Completed initialization in 13 ms

而且我的瀏覽器中有一個 404 錯誤，我準確地說我在 Eclipse 上的專案沒有這個問題。

這是我的 POM 檔案

https://codebeautify.org/alleditor/y2226566c

uj5u.com熱心網友回復：

問題只是與 Java 版本和 Java 庫版本有關。jar中的匯出也有問題，當我們制作可運行的jar檔案匯出時，需要選擇將所需的庫復制到子檔案夾而不是其他兩個選項。
