jsp - 如何响应 JSP Servelet 请求的自定义字符串

Question

protected void doPost(HttpServletRequest request, 
            HttpServletResponse response) throws ServletException, IOException {
....
....
getServletContext().getRequestDispatcher("/output.jsp").forward(request, response);
}

我需要的是不要在doPost. 我有一个字符串（平面文本），我需要像 Servlet 请求一样响应它。我怎样才能做到这一点？

Answer 1

你可以这样做：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  response.setContentType("text/html");
  PrintWriter out = response.getWriter();
  out.append("Your string goes here");
  out.close();
}

Answer 2

//getServletContext().getRequestDispatcher("/message.jsp").forward(request, response);
response.getWriter().println(output); // output is the custom string
