java读取照片Exif信息到实体类

前言

1.总共读出来了228个参数信息，但是我挑选了36个我认为比较有价值的参数，弄成了实体类

（其实是因为很多参数我看不明白是啥意思）

2.为了方便，所以实体类里我直接用中文字段了

效果图

导入依赖

        <!-- 读取照片元信息 -->
        <dependency>
            <groupId>com.drewnoakes</groupId>
            <artifactId>metadata-extractor</artifactId>
            <version>2.19.0</version>
        </dependency>

算法代码

public static void main(String[] args) throws ImageProcessingException, IOException {
        File file = new File("C:\\Users\\13301\\Desktop\\漫漫星河\\IMG_1252.JPG");
        ImageExifInfoVo imageExifInfoVo = readImageExif(file);
        System.out.println(imageExifInfoVo);

    }
