Javaweb项目中从servlet跳转到jsp页面出现乱码

在创建的servlet中要按照如下顺序：

  public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

 request.setCharacterEncoding("UTF-8");
       response.setCharacterEncoding("UTF-8");
                                                  //一定是先设置字符再写PrintWriter，不然跳转到jsp页面会乱码
     response.setContentType("text/html");
     PrintWriter out = response.getWriter();

 }
