java链接ceph报错

写了个java链接ceph进行对象存储的demo，结果报以下的错：

Exception in thread "main" com.amazonaws.services.s3.model.AmazonS3Exception: null (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: null), S3 Extended Request ID: null

花了好一会功夫，找到缘由：com.amazonaws的依赖包是最新版，向下支持很差

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-s3</artifactId>
    <version>1.11.39</version>
</dependency>

 

解决办法：更改maven依赖以下便可，将version改设为一个较老的版本：

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-s3</artifactId>
    <version>1.10.69</version>
</dependency>
