loin.jsp介面
<html> <body> <h2>Hello World!</h2> <%--這裡的提交路徑，需要尋找到專案的路徑--%> <%--${pageContext.request.contextPath}代表當前的專案--%> <form action="${pageContext.requset.contexPath}/login" method="get"> 使用者名稱：<input type="text" name="username"><br> 密碼：<input type="password" name="password"><br> <input type="submit" value="登入"> </form> </body> </html>
Servlet
public class RequestTest extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { System.out.println("請求到了這個頁面"); resp.setCharacterEncoding("utf-8"); req.setCharacterEncoding("utf-8"); String username = req.getParameter("username"); String password = req.getParameter("password"); //重定向 resp.sendRedirect("/response_war/success.jsp"); } @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { doGet(req, resp); } }
web.xml配置
<servlet> <servlet-name>requset</servlet-name> <servlet-class>com.kuang.servlet.RequestTest</servlet-class> </servlet> <servlet-mapping> <servlet-name>requset</servlet-name> <url-pattern>/login</url-pattern> </servlet-mapping>
