Public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException{
______
out.println("hi kitty! ");
out.close();
}
运行Servlet时输出：hi kitty!
则应在此Servlet下划线处填充如下代码
举一反三
- 阅读下列的代码 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException{ out.println("hello kity!"); } 若使Servlet运行的结果为hi kitty！,填写在空白处的代码为() 则应在此Servlet下划线处添加如下()代码
- LoginServlet是一个Servlet类，代码如下 public class LoginServlet extends ___________ { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { … } public void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { … } } 在下划线处应填写（）
- 智慧职教: 在Servlet中有如下代码段： public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { RequestDispatcher dis; _____________________________; dis.forward(request,response); }
- 给定如下所示的Java Servlet代码片段，用户在浏览器地址栏中键入正确的请求URL并回车后，在控制台上显示的结果是（）。 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{ System.out.println(“get”); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{ System.out.println(“post”); } protected void service(HttpServletRequest req, HttpSergvletResponse resp) throws ServletException, IOException{ System.out.println(“service”); }
