Answer 1

檢查您映射 url 的主 servlet 文件或 web.xml 文件中的注釋。 我的意思是檢查您的 servlet 頁面或 web.xml 中的以下代碼。 可能您錯過了在任何 urlPatterns 前面放一個“/”符號。

@WebServlet(name = "AkterHossainBookLibrary", urlPatterns = {
    "/", "/login", "/logout", "/add-book", 
    "/edit-book", "/delete-book", "/book-list", "/search", 
    "/order-book", "/refund-book" })
public class BookLibraryServlet extends HttpServlet {

...
...

}

如果有效，請告訴我。

祝你好運

Answer 2

檢查類路徑，確保它包含 servlet-api.jar 包。

Answer 3

少 servlet-api.jar

java構建路徑-》添加庫-》eclipse服務器庫-》eclipse tomcat運行庫

Answer 4

我已經多次遇到這個問題。 通常發生在我在 VS Code 中查看我的代碼然后返回 Eclipse 時。 一旦我清理了項目並再次構建它，它就可以正常工作。
