import jakarta.servlet.*; import jakarta.servlet.http.*; import jakarta.servlet.annotation.*; import java.io.IOException; @WebServlet(name = "ForwordServlet", value = "/ForwordServlet") public class ForwordServlet extends HttpServlet{ @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=utf-8"); request.setAttribute("usernamer","张三"); RequsetDispatcher dispatcher = request.getRequestDispatcher("/ResultServlet"); dispatcher.forward(request,response); } @Override protected void doPost这段代码的RequestDispacher错误怎么解决(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request,response); } }

这段代码中的错误在于"RequsetDispatcher"拼写错误，应为"RequestDispatcher"。正确的代码应该是:

import jakarta.servlet.*;
import jakarta.servlet.http.*;
import jakarta.servlet.annotation.*;
import java.io.IOException;

@WebServlet(name = "ForwordServlet", value = "/ForwordServlet")
public class ForwordServlet extends HttpServlet{

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html;charset=utf-8");
request.setAttribute("usernamer","张三");
RequestDispatcher dispatcher = request.getRequestDispatcher("/ResultServlet");
dispatcher.forward(request,response);
}

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request,response);
}
}
