文件名的截取

1.截取不带后缀的文件名

String resourceName=resourceSearchBean.getFileName();

if(StringHelper.isNotEmpty(resourceName)&&resourceName.length()>0);

{

 int dot = resourceName.lastIndexOf('.');

 if ((dot >-1) && (dot < (resourceName.length()))) {   

  return resourceName.substring(0, dot);   

 }

}

2.截取文件后缀名

    public static String getExtensionName(String filename) {
        if ((filename != null) && (filename.length() > 0)) {
            int dot = filename.lastIndexOf('.');
            if ((dot >-1) && (dot < (filename.length() - 1))) {
                return filename.substring(dot + 1);
            }
        }
        return filename;
    }
