不应该直接实例化CachedRowset的实现——使用其提供程序获取实例:请参见 http://docs.oracle.com/javase/7/docs/api/javax/sql/rowset/RowSetProvider.html (从JDK7开始提供)

实际上,cachedrowset的接口和相关工厂是标准/可移植的。

像下面这样的东西应该能起到作用:

CachedRowSet crs = RowSetProvider.newFactory().createCachedRowSet();
crs.populate(myResultSet);

以下是我改进的 cachedrowsetimpl 支持mysql 5.x名称和标签。基于thiy guy的实现 http://tech.groups.yahoo.com/group/Firebird-Java/message/10715

Oracle实施 是 开放源代码

这个问题错误地指出oracle行集实现是专有的。它不是;它已经是开源的了。

源代码作为自由软件发布在 GNU General Public Library (GPL) version 2 许可证 "Classpath" exception . 读 the source code 去看执照。

所以他们不能撤回。你和其他人可以自由地维护或修改这些类,只要你遵守gpl的条款。

JDBC驱动程序实现

另外,一些JDBC驱动程序提供了行集的实现。我不知道是否有开源的,但那将是一个探索的途径。
