我创建了一个简单的骆驼路由来轮询本地目录中的文件并将它们上传到我大学的 Ceph (S3) 服务器。我正在使用带有camel-aws S3组件的apache camel 2.20.0，当我在uri中设置multiPartUpload = false（默认值）时，一切正常，但如果我更改为multiPartUpload = true，它会失败。

我知道我的 s3 密钥或 s3 访问密钥没有任何问题，因为当我设置 multiPartUpload=false 时，一切正常（没有需要在密钥中转义的疯狂加号 (+) 字符）。

这是堆栈跟踪：

我的 camel-context.xml 看起来像：

            <log message="Done sending file." />

        </route>
    </camelContext>
</beans>

我尝试了很多东西，例如：

  • 将 CamelAwsS3ContentMD5 标头设置为文件的 MD5 哈希（这对多部分文件没有意义）
  • partSize 参数的各种设置
  • 从非常大到非常小的不同大小的文件
  • 设置系统参数：System.setProperty("com.amazonaws.services.s3.disablePutObjectMD5Validation", "true");

如果我为骆驼打开跟踪调试，它没有多大帮助：

我需要多部分上传工作的原因是非常大的文件，但我无法让它在任何文件大小上工作。

结果...

由于端点是 Ceph 服务器，除非您在 S3 ClientConfiguration 中将 signerOverride 设置为“S3SignerType”，否则分段上传将不起作用，如下所示：

<bean id="amazonClient" class="com.amazonaws.services.s3.AmazonS3Client">
    <constructor-arg>
        <bean class="com.amazonaws.auth.BasicAWSCredentials">
            <constructor-arg name="accessKey" value="${s3AccessKey}" />
            <constructor-arg name="secretKey" value="${s3SecretKey}" />
        </bean>
    </constructor-arg>

 <!-- *** The following option must be set in order for multipart uploads to work on a Ceph server *** -->
    <constructor-arg>
        <bean class="com.amazonaws.ClientConfiguration">
            <property name="signerOverride" value="S3SignerType" />
        </bean>
    </constructor-arg>


    <property name="s3ClientOptions">
        <bean class="com.amazonaws.services.s3.S3ClientOptions">
            <property name="pathStyleAccess" value="true" />
        </bean>
    </property>
    <property name="endpoint" value="${s3Endpoint}" />
</bean>

也许这个要求会在以后的 Ceph 版本中消失，我连接的版本早于 v12（Luminous），但我不确定确切的版本。或者，这可能是服务于 Ceph 集群的 HTTPS 前端的限制——我不确定。
