jsp - 如何响应 JSP Servlet 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 结束时重定向到另一个 JSP 页面。我有一个字符串(平面文本)，我需要像 Servlet 请求一样响应它。我该怎么做？

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();
}
