https://github.com/jankotek/MapDB might do part of what you want. That library provides several persistent list, set and map implementations, including a b-tree map.
A late contribution, I know. I myself don't need the excitement of choosing a Java DBM library. I need one merely to minimize memory usage in certain cases. (For actual persistence I'd use JPA.) There currently are 4 different JDBM projects in various states.
Luckily the Apache directory server comes with a JDBM library and my exciting times seem to be gone forever! The library can be used separately and it seems to be based on one of the four implementations. It's also on MVNRepository.

JDBM4 was renamed to MapDB
值得一提的现代项目：
Modern projects worth mentioning:
https://github.com/jankotek/MapDB 可能会完成您想要的部分操作。该库提供了几个持久列表、集合和映射实现，包括 b 树映射。

我知道，这是一个迟来的贡献。
我自己不需要选择 Java DBM 库的兴奋感。我需要一个只是为了在某些情况下最大限度地减少内存使用。 （为了实现实际持久性，我会使用 JPA。）目前在不同的州有 4 个不同的 JDBM 项目。
幸运的是，Apache 目录服务器附带了 JDBM 库，我的激动人心的时光似乎一去不复返了！该库可以单独使用，它似乎基于四种实现之一。它也在 MVNRepository 上。
