如何执行从Javascript到JSP的Ajax调用？

JSP是这项工作的错误工具。输出将被模板文本损坏。用Servlet替换它。您只需要流式传输

URLConnection#getInputStream()

HttpServletResponse#getOutputStream()

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {    URLConnection connection = new URL("http://other.service.com").openConnection();    // Set necessary connection headers, parameters, etc here.    InputStream input = connection.getInputStream();    OutputStream output = response.getOutputStream();    // Set necessary response headers (content type, character encoding, etc) here.    byte[] buffer = new byte[10240];    for (int length = 0; (length = input.read(buffer)) > 0;) {        output.write(buffer, 0, length);    }}

就这样。将此servlet映射
