上述代码的输出为:1.0, 1.1, 1.2, CURRENT

代替“当前”标签,我想“获取版本号”,如 2.0 或 3.0 等,这是最新的文档版本号。

需要的输出如下:

首先,这一行:

int versionsCount = collection.getValueCount("r_object_id");

应该是

int versionsCount = collection.getValueCount("r_version_label");

并且必须在 while(collection.next()) 循环中,这样它将正确地迭代所有 r_version_label 值,因此代码现在将输出:

1.0
1.1
1.2 
CURRENT
2.0

您现在可以摆脱 CURRENT (或者通常摆脱所有无法解析为浮点数的非值)。
