java使用aws S3中的所有文件，其中deleteAfterRead=false

1 周，6 日 Questions & Answers 1001

有没有一种方法可以在不从S3中删除文件的情况下使用S3存储桶中的所有文件（在S3中，大约有15000个文件）

由于aws-s3中的noop参数滞后，以下配置存在问题。问题是：它不断地反复检索相同的5个文件

    <endpoint id="fbPage" uri="aws-s3://bucket?amazonS3Client=#aws-credential&amp;deleteAfterRead=false&amp;maxMessagesPerPoll=5&amp;prefix=dev/facebook/page"/>

    <route id="consumeS3FbPage">
        <from uri="ref:fbPage"/>
        <choice>
            <when>                  
                <simple>${header.CamelAwsS3ContentLength}  &gt; 0</simple> 
                <log message="Page File detected: ${header.CamelAwsS3Key}"/>
                <bean ref="dfaReportingRePull" method="s3toElasticFormat"/>

                <setHeader headerName="CamelHttpMethod">
                    <constant>POST</constant>
                </setHeader>
                <to uri="http://localhost:9200/fb_camel/page/_bulk"/>
                <log message="Success"/>
            </when>
            <when>
                <simple>${header.CamelAwsS3ContentLength} == 0</simple>
                <log message="Empty content, Probably the s3 key Folder itself: ${header.CamelAwsS3Key}"/>
            </when>
        </choice>               
    </route>

以下日志显示多次检索到同一文件：

即使我使用幂等函数，它也只是检测到所有5个文件都是重复的，因此被忽略

我想知道我是不是真的读了，然后把它放回去行吗？不，当我查看http://camel.465427.n5.nabble.com/camel-aws-s3-get-only-files-I-need-td5714095.html中的代码时，似乎代码只会在aws s3当前返回列表上的列表中循环

当我查看代码列表ObjectsRequest时。java，我知道有一种方法可以定义一个标记，它指示最后一次处理的s#key。有没有办法通过Camel Spring DSL进入这个市场？[更新]没有

在深入研究代码之后，我找到了这种情况的根本原因。而且可以通过这张JiRA票追踪：https://issues.apache.org/jira/browse/CAMEL-8431

注意：Camel版本是2.14.0

有 Java 编程相关的问题?
