ok, I just found it is not related with tomcat or struts.
I just use this code:
import java.util.Arrays;
import javax.imageio.ImageIO;
public class ListImageFormatters {
public static void main(String[] args) {
String[] readerFormatNames = ImageIO.getReaderFormatNames();
//[BMP, bmp, jpg, JPG, wbmp, jpeg, png, PNG, JPEG, WBMP, GIF, gif]
System.out.println(Arrays.toString(readerFormatNames));
//[jpg, BMP, bmp, JPG, jpeg, wbmp, png, JPEG, PNG, WBMP, GIF, gif]
String[] writerFormatNames = ImageIO.getWriterFormatNames();
System.out.println(Arrays.toString(writerFormatNames));
}
}
and it will start the Bootstrap too.
so, look like it is belong to JDK part.
but I don’t understand it still. is there anyone can share some tips to me?
thanks so much
