问题描述

我正在尝试通过非常基本的测试对s3 sdk进行测试，并获得以下错误.

I am trying to s3 sdk with very basic test and getting below error.

由以下原因引起:java.lang.NoSuchFieldError:SIGNING_REGION 在com.amazonaws.services.s3.AmazonS3Client.createRequest(AmazonS3Client.java:4227) 在com.amazonaws.services.s3.AmazonS3Client.createRequest(AmazonS3Client.java:4203) 在com.amazonaws.services.s3.AmazonS3Client.listBuckets(AmazonS3Client.java:929) 在com.amazonaws.services.s3.AmazonS3Client.listBuckets(AmazonS3Client.java:936)

Caused by: java.lang.NoSuchFieldError: SIGNING_REGION at com.amazonaws.services.s3.AmazonS3Client.createRequest(AmazonS3Client.java:4227) at com.amazonaws.services.s3.AmazonS3Client.createRequest(AmazonS3Client.java:4203) at com.amazonaws.services.s3.AmazonS3Client.listBuckets(AmazonS3Client.java:929) at com.amazonaws.services.s3.AmazonS3Client.listBuckets(AmazonS3Client.java:936)

推荐答案

谢谢大家，问题在于Spring提出的aws-core依赖版本不一致.手动提供核心版本(1.11.288)后，它可以解决问题.如前所述，如果我们不只是在春季启动时将版本明确放在pom中，它也可以解决此问题.

Thank you everyone, issue was with having not consistent version of aws-core dependency that is pulled by spring. After manually giving core version (1.11.288) it resolves issue. As mentioned if we just not put version explicitly in pom in spring boot, it can also resolve this issue.
