//1.指定目录读取文件
File file = new File(realPath, fileName);
//2.将文件读取为文件输入流
FileInputStream fileInputStream = new FileInputStream(file);
//设置附件形式
httpServletResponse.setHeader("content-disposition","attachment;filename="+ URLEncoder.encode(fileName,"UTF-8"));
//3.获取响应输出流
ServletOutputStream outputStream = httpServletResponse.getOutputStream();
//4.输入流复制给输出流

byte[] b=new byte[1024];

当把前端参数改为"1.docx"时，能正常接收
简历.docx
当参数改为上面的"简历.docx"时，后端接收不到
当不使用restful时，能够后端能正常接收请求
希望使用restful也能接收中文参数，或者明白为什么会不能使用中文参数
到Tomcat的server.xml里面配置一下编码，
uriencode=utf-8
