@WebServlet("/list")
public class DownloadListServlet extends HttpServlet {

	protected void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		// 获取download目录下所有的文件名（放置下载文件的文件目录）
		String realPath = getServletContext().getRealPath("tmp");
		
		File file = new File(realPath);
		File[] list = file.listFiles();
		response.setCharacterEncoding("utf-8");
		response.setContentType("text/html;charset=utf-8");
		for (File f : list) {
			String name = f.getName();
			// 对内容使用url编码 编码之后的内容ie可以解析
			String encodeName = URLEncoder.encode(name, "utf-8");
			System.out.println(name);
			response.getWriter().write("<a href='http://192.168.1.107:8080/spring14/tmp/" + name + "'>" + name + "</a><br/>");
