1. 获取API-key

https://help.aliyun.com/zh/model-studio/developer-reference/get-api-key?spm=a2c4g.11186623.0.0.5a1a4d33o52o7l

2. 导入依赖

 <!-- https://mvnrepository.com/artifact/com.alibaba/dashscope-sdk-java -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dashscope-sdk-java</artifactId>
            <version>2.15.1</version>
        </dependency>

3. 调用方法代码
