AWS S3 Java文件上传，无访问密钥/凭据

我是AWS的新手，
我使用AWS CLI在本地配置我的AWS凭据，因为我无法将IAM角色连接到我的笔记本电脑，
我可以通过EclipseIDE的AWS工具包插件查看正确配置的凭据。
我引用了这个答案-，

有人能帮助我理解如何在代码中设置S3存储桶所在的区域吗？
还是从aws配置命令期间设置的区域中提取区域？
当我尝试使用

s3client.setRegion

方法时出现错误。

我无法在本地测试这段代码，这会引发以下错误-

com.amazonaws.SdkClientException: Unable to load credentials from service endpoint

以下是我将文件上载到AWS S3的代码-

AmazonS3 s3client = AmazonS3ClientBuilder.standard()
                      .withCredentials(new InstanceProfileCredentialsProvider(false))
                      .build();
//s3client.setRegion(com.amazonaws.regions.Region.getRegion(Regions.EU_CENTRAL_1));
PutObjectResult result = s3client.putObject(new PutObjectRequest(BUCKET_NAME, BASE_PATH + localFile.getName(), localFile));

完成错误日志-

The legacy profile format requires the 'profile ' prefix before the profile name. The latest code does not require such prefix, and will consider it as part of the profile name. Please remove the prefix if you are seeing this warning.

传统配置文件格式要求在配置文件名称之前加上“profile”前缀。最新代码不需要这样的前缀，并将其视为配置文件名称的一部分。如果看到此警告，请删除前缀。
