设置了response.setContentType("text/html;charset=utf-8");仍然乱码

设置了response.setContentType("text/html;charset=utf-8");仍然乱码

是放在了第一行，也乱码

@WebServlet(name = "CookieTest", urlPatterns = "/CookieTest")
public class CookieTest extends HttpServlet {
private static final long serialVersionUID = 1L;

@Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    response.setContentType("text/html;charset=utf-8");

    Cookie[] cookies = request.getCookies();//获取所有的Cookie
    boolean flag = false;

打开F12，响应头也没问题

HTTP/1.1 500
Content-Type: text/html;charset=utf-8
Content-Length: 88
Date: Thu, 10 Nov 2022 11:09:54 GMT
Connection: close

所有的Servlet都报错
求指点？

你用的什么语言，你把整体代码发给我看看

你接受请求的时候应该是request.setCharacterEncoding("utf-8");
响应的应该是response.setContentType("text/html;charset=utf-8");

servletResponse.setCharacterEncoding("utf-8");
servletRequest.setCharacterEncoding("utf-8");
servletResponse.setContentType("text/html;charset=UTF-8");
