1、所需jar包
2、编写测试类
import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import com.drew.imaging.jpeg.JpegMetadataReader;
import com.drew.imaging.jpeg.JpegProcessingException;
import com.drew.metadata.Directory;
import com.drew.metadata.*;
import com.drew.metadata.Tag;
import com.drew.metadata.exif.ExifIFD0Directory;
public static void main(String[] args) throws JpegProcessingException, IOException {
File img = new File("C:/Users/Administrator/Desktop/布局图.jpg");
System.out.println("File Name:" + img.getName());
Metadata metadata = JpegMetadataReader.readMetadata(img);
System.out.println("Directory Count: "+metadata.getDirectoryCount());
System.out.println();
//输出所有附加属性数据
for (Directory directory : metadata.getDirectories()) {
System.out.println("******\t" + directory.getName() + "\t******");
for (Tag tag : directory.getTags()) {
System.out.println(tag);
System.out.println(tag.getTagName() + ":" + tag.getDescription());
}
}
}
