Is it really that important to you zhouyanming???? If so, maybe its time to fix it yourself and contribute a fix back. That is the model of Open Source. Just sayin...

I have added the necessary hooks in 5.0 codebase which is expected Spring timeframe. Its merely a matter of sifting through the incredibly easy reading annotation binding code and hooking that in. The 5.0 support boils down to org.hibernate.mapping.ForeignKey#creationEnabled, which is true by default. We just need annotation binding code to call org.hibernate.mapping.ForeignKey#disableCreation properly.
