大三学的jsp与servlet跟着课本敲前面还正常到cookie就一直end求求大佬看下
代码如下
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
@WebServlet("/SetCookie")
public class SetCookie extends HttpServlet {
public void doGet( HttpServletRequest request,HttpServletResponse response) throws IOException {
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
request.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE html><html><head><title>Set Cookie</title></head>");
out.println("<body>");
String str="Hellojavawebprogram";
Cookie cookie = new Cookie("name",str);
response.addCookie(cookie);
out.println("<br>");
out.println("ADD Cookie ok");
out.println("</body></html>");
out.flush();
out.close();
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {
doGet(request, response);
}
public void init() throws ServletException {}
}
