下载文件中文乱码问题+路径斜杠问题

（1）路径斜杠问题：

vulnFile.setPath(map.get("path").toString().replace("\\", "\\\\"));

（2）文件名称中文乱码问题：

1. String code = EncodingUtil.getEncoding(name);
      try {
       String names = new String(name.getBytes(code),"ISO8859-1");
       this.fileName = names.toString();
      } catch (UnsupportedEncodingException e) {
       e.printStackTrace();
      }

2. 
    public static  String getEncoding(String str) { 
           String encode = "GB2312"; 
           try { 
               if (str.equals(new String(str.getBytes(encode), encode))) { 
                   String s = encode; 
                   return s; 
               } 
           } catch (Exception exception) { 
           } 
           encode = "ISO-8859-1"; 
           try { 
               if (str.equals(new String(str.getBytes(encode), encode))) { 
                   String s1 = encode; 
                   return s1; 
               } 
           } catch (Exception exception1) { 
           } 
           encode = "UTF-8"; 
           try { 
               if (str.equals(new String(str.getBytes(encode), encode))) { 
                   String s2 = encode; 
                   return s2; 
               } 
           } catch (Exception exception2) { 
           } 
           encode = "GBK"; 
           try { 
               if (str.equals(new String(str.getBytes(encode), encode))) { 
                   String s3 = encode; 
                   return s3; 
               } 
           } catch (Exception exception3) { 
           } 
           return ""; 
       }
