记录一下使用正则匹配引号中逗号

栗子：

private static String regex(String str){
     Pattern p = Pattern.compile(",(?!(?:[^\"]*\"[^\"]*\")*[^\"]*$)");
     Matcher m = p.matcher(str);
     StringBuffer sb=new StringBuffer();
     while(m.find()){
        m.appendReplacement(sb,m.group().replace(",", "_"));
     }
     m.appendTail(sb);
     return sb.toString();
 }

 public static void main(String[] args) {
     String str = "\"2019-12-27T00:00:00.000Z\",\"5dfdaae60f2,56d5a36,351833\",\"GODROP\",\"AG\",\"5e02314ef5f6ec92c73207d5\",\"Caribeen-GP-1224\",2,0,0,0,0,0,3";
     System.out.println(regex(str));
 }
