java对接阿里云的通用分割，将代码原封不动复制进来，执行结果失败，咨询阿里云的人员之后，由于jar包冲突导致，需要引入一些特定的包版本来实现

pom引用

代码

只需要改pom，对于获取环境变量中的ak信息，完全没必要。

public class AliyunApiService {
    public static com.aliyun.imageseg20191230.Client createClient(String accessKeyId, String accessKeySecret) throws Exception {
        /*
          初始化配置对象com.aliyun.teaopenapi.models.Config
          Config对象存放 AccessKeyId、AccessKeySecret、endpoint等配置
         */
        com.aliyun.teaopenapi.models.Config config = new com.aliyun.teaopenapi.models.Config()
                .setAccessKeyId(accessKeyId)
                .setAccessKeySecret(accessKeySecret);
        // 访问的域名
        config.endpoint = "imageseg.cn-shanghai.aliyuncs.com";
        return new com.aliyun.imageseg20191230.Client(config);
    }

    public static void main(String[] args_) throws Exception {

        String accessKeyId = "";
