Java sting 數組 取消 {“”}

直接上代碼

param=""

String roleIds = param.replace("\"", "");
//分割權限id
String[] splitroleIds = roleIds.split(",");
    //如果splitroleIds等於"" 表示沒有需要給用戶設置權限
    List<String> tmp = new ArrayList<String>();
    for (String str : splitroleIds) {
        if (str != null && str.length() != 0) {
            tmp.add(str);
        }
    }
    splitroleIds = tmp.toArray(new String[0]);
