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

xml 复制代码
        <!-- 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

java 复制代码

        System.out.println(imageExifInfoVo);

    }
