package cookie;
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;
@WebServlet(name = "/Cookiedemo1")
public class Cookiedemo1 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Cookie c=new Cookie("msg","hello");
response.addCookie(c);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response);
}
}
這是我的servlet類對cookie進行添加檔案名為Cookiedemo1
package cookie;

@WebServlet(name = "/coookiedemo2")
public class Coookiedemo2 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Cookie[] cs = request.getCookies();
if(cs!=null){
for(Cookie c:cs){
String name= c.getName();
String value=https://bbs.csdn.net/topics/c.getValue();
System.out.println(name+":"+value);
}
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response);
}
}
這是我的servlet類對cookie進行接受檔案名為Cookiedemo2
但進入網頁就莫名報404，其他網頁都能訪問，且在洗掉連接重連時因為這個會報錯
