Java代碼逐步解析照片拿到GPS位置數(shù)據(jù)，附上步驟講解，附上源代碼和jar包依賴

1.前提條件

第一，檢查你圖片是否是高清原圖；
第二，檢查你的圖片是否來自IPhone設(shè)備;
第三，檢查你拍照片時，是否打開了GPS；
三者缺一不可

2.代碼環(huán)境

A：需要的Jar包：

 <dependency>
            <groupId>com.drewnoakes</groupId>
            <artifactId>metadata-extractor</artifactId>
            <version>2.12.0</version>
 </dependency>

B：開發(fā)環(huán)境

1.maven 引入jar包
2.JDK 1.8
3.windows OS

C：核心代碼

import com.drew.imaging.jpeg.JpegMetadataReader;
import com.drew.imaging.jpeg.JpegProcessingException;
import com.drew.metadata.Directory;
import com.drew.metadata.Metadata;
import com.drew.metadata.Tag;

import java.io.File;
import java.io.IOException;
import java.util.Iterator;
public class PictureTest {
    public static  void readPic() {
        System.out.println("開始讀取圖片信息...");
        File jpegFile = new File("18.jpg");
        Metadata metadata;
        try {
            metadata = JpegMetadataReader.readMetadata(jpegFile);
            Iterator<Directory> it = metadata.getDirectories().iterator();
            while (it.hasNext()) {
                Directory exif = it.next();
                Iterator<Tag> tags = exif.getTags().iterator();
                while (tags.hasNext()) {
                    Tag tag = (Tag) tags.next();
                    System.out.println(tag);
                }
            }
            System.out.println("圖片信息讀取完成！");
        } catch (JpegProcessingException e) {
            e.printStackTrace();
        } catch (IOException e) {
        }
    }
}
