• AmazonRekognition-Java对接


    AmazonRekognition-Java对接

      AmazonRekognition类似于百度EasyDL,是一款图像分析服务,检测图像分类及图像内容等。

    1、项目创建

      项目创建的方式有一下三种方式:

      1:AWS官网创建

      2:CLI创建

      3:编码创建(Java)

    AWS官网创建文档见:

      链接:https://pan.baidu.com/s/1WMnUIjNug53YEzWMXENVKw
      提取码:flny

    2、依赖

            <!--AmazonRekognition依赖-->
            <dependency>
                <groupId>com.amazonaws</groupId>
                <artifactId>aws-java-sdk-rekognition</artifactId>
                <version>1.11.759</version>
            </dependency>

    3、功能代码

    1、客户端验证连接

      客户端连接方式及问题见https://www.cnblogs.com/StefanieYang/p/13212508.html

    2、功能
