工具类已经实现Base64二维码图片识别和路径图片识别
所需maven依赖
<!--二维码生成和解析相关的jar包【生成】【解析】-->
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>javase</artifactId>
<version>3.2.1</version>
</dependency>
<!-- /artifact/com.google.zxing/core -->
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>core</artifactId>
<version>3.3.3</version>
</dependency>
工具类代码，直接复制修改package可用
