其实解决bug很简单，是缺了个包，而且这个是运行时异常

  <dependency><groupId>com.aliyun</groupId><artifactId>tea-openapi</artifactId><version>0.2.1</version></dependency><!-- 还有这个识别用的包 --><dependency><groupId>com.aliyun</groupId><artifactId>ocr20191230</artifactId><version>2.0.1</version></dependency>

package com.utils;/*
