Question

我正在尝试处理Java中基本HTML表单的输入。但是，每当我单击表单上的提交按钮时，我都会收到此错误：“在此服务器上找不到请求的URL / formHandler。”

以下是表单和Java servlet，它们都位于同一目录中，以及该站点的所有其他文件。有没有找到servlet的想法？

FORM

<form method="post" action="formHandler">
                <label for="name">Name: </label>
                <input name="name" defaultValue="name"/><br/>
                <label for="email">Email: </label>
                <input name="email" defaultValue="email"/><br/>
                <label for="details">Further Details or Comments</label><br/>
                <input name="details" defaultValue="details"/><br/><br/>
                <input type="submit" value="Submit"/>
</form>

SERVLET

@WebServlet("/formHandler")
public class FormHandler extends HttpServlet {

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {

        String name = request.getParameter("name");
        String email = request.getParameter("email");
        String details = request.getParameter("details");

        PrintWriter writer = response.getWriter();
        String htmlRespone = "<html>";
        htmlRespone += "<h2>Thank you " + name + ", a confirmation email will be sent to " + email + " shortly.</h2>";
        htmlRespone += "</html>";

        writer.println(htmlRespone);

    } 
}

找不到表单操作URL
