我刚刚将我们的Artifactory OSS实例从5.4.5迁移到5.8.3（独立，使用Derby）
我按照https://www.jfrog.com/confluence/display/RTF/Upgrading+Artifactory的建议，基本上做了：
两者都运行良好，服务器恢复正常运行。
但是，我现在在实例启动时logs/artifactory.log发出警告
2018-01-24 16：12：07,633 [art-exec-4] [WARN]（oasjmpRepoPathChecksumMigrationJobDelegate：110） - 路径校验和计算作业（对于现有工件）已被禁用且不会运行，仍然有数据库中没有路径校验和值的5348个工件。未来版本的Artifactory可以强制执行此转换作为升级的先决条件。
我找不到更多有关此警告的实质性解释。
我认为这与文件系统上的工件布局有关（参见https://www.jfrog.com/confluence/display/RTF/Checksum-Based+Storage#Checksum-BasedStorage-Overview）。工件仍按照SHA-1checksums而不是SHA-256校验和进行布局。
我的假设是否正确？我该如何“修复”这个警告...
编辑：@Ariel要求进行更多测试：
echo "artifactory.sha2.migration.job.enabled=true" >> etc/artifactory.system.properties
查看与此迁移相关的日志，似乎迁移作业认为已迁移所有内容，并且启动检查发现应迁移的2,000个工件。

这个文档记录很少 - 我不得不下载Artifactory OSS源代码和grep以获得答案 - 但显然Path Checksum迁移与SHA-256迁移完全不同。
我想你希望artifactory.pathChecksum.migration.job.enabled=true中有artifactory.system.properties。

Sha-256的操作不是自动完成的。您需要手动设置它才能运行。这样做是为了不会导致用户环境过载。 如果您想激活它，请点击以下链接： https://www.jfrog.com/confluence/display/RTF/Checksum-Based+Storage#Checksum-BasedStorage-MigratingtheDatabasetoIncludeSHA-256
