如何存取WEB-INF/views/some.jsp？彈簧MVC

我成功地將我的 web 應用程式部署到 Tomcat 本地主機。我的應用程式有 2 個頁面：localhost:8080/spring-mvc 和 localhost:8080/home。第一頁有第二頁的連結。當我啟動我的應用程式時，它成功打開第一頁，但是當我點擊連結進入第二頁時，出現錯誤：

HTTP 狀態 404 – 找不到。

似乎無法存取 WEB-INF/view 資料夾。你能幫我解決這個問題嗎？

根本原因 tomcat jasper 套件中提供了解析 JSP 路徑所需的類，並且 pom.xml 中未添加依賴項。因此，Spring Boot應用程式無法解析jsp路徑。

解決方案 依賴類別在tomcat jasper中可用。
