Java 用jackrabbit压缩文件

我正在尝试为jackrabbit上传，但zip文件下载已损坏

maven依赖项：

<dependency>
        <groupId>org.apache.jackrabbit</groupId>
        <artifactId>jackrabbit-jcr2dav</artifactId>
        <version>${jackrabit.version}</version>
    </dependency>

    <dependency>
        <groupId>javax.jcr</groupId>
        <artifactId>jcr</artifactId>
        <version>${javax.jcr.version}</version>
    </dependency>

它将zip文件上载到jackrabbit，但是当我下载该文件时，该文件已损坏

它是2.15.1版本的jackrabbit，服务器是2.10.1版本的，我切换到2.13版，它工作了

这可能是因为你没有关闭一个流。

你似乎认为你可以将二进制流转换为ASCII文本，然后再转换回二进制流而不丢失信息？我忘了删除这些转换为ASCII的行。但是无论如何，这将继续上传压缩文件，除非你必须这样做，否则不要使用奇数版本的小版本。这些是“不稳定”的版本。最新的稳定版本是2.14.0。看见
