Java给excle文件命名时候的正则表达式效验

今天使用easyExcle插件下载excle文件里面无数据，控制台报错：

java.lang.IllegalArgumentException: Invalid char (/) found at index (19) in sheet name 'XXX'

加上正则表达式对excle名称进行效验

String excleName = "123";
String pattern = "^[^\\\"\\?\\*\\:\\<\\>\\|\\/\\\\]"+"{"+excleName.length()+",}$";
        Pattern r = Pattern.compile(pattern);
        Matcher m = r.matcher(excleName);
        if (!m.matches()){
             System.out.println("excle名称不能包含[\\,/,:,*,?,<,>,|]字符");
        }
