java鏈接ceph報錯

寫了個java鏈接ceph進行對象存儲的demo，結果報以下的錯：

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
    at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1529)

花了好一會功夫，找到緣由：com.amazonaws的依賴包是最新版，向下支持很差

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

 

解決辦法：更改maven依賴以下便可，將version改設爲一個較老的版本：

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