SpringとのJDO統合..？

Question

Springと統合したい場合、Kodo JDOを使用する必要がありますか？私の理解から、コドは自由ではありません。 Springを使用したJDOの無料実装はありますか？このようなデモにはソースコードが付属していますか？

Answer 1

Out of date Spring no longer supports JDO

Spring JDO support should be able to work with any implementation that is compliant to the JDO spec.

For example, here is a tutorial for using the open source JPox JDO implementation with Spring.

Answer 2

Datanucleus. They are the maintainer of JPOX, the reference implementation of JDO. The HUGE advantage of using Datanucleus for your application development is that the Google App-Engine uses it. That means it can be easily deployed to the Google Cloud and you don't have to worry a bit about what happens to persist the data, or that it will scale in a high reliability, high availability manner.
