用hibernate和postgresql保存实体后检索序列int的正确方法？

Question

This is how I'm getting the id from save(entity) method:

Serializable save = hibernateTemplate.save(article);
return Integer.valueOf(save.toString());

Being a complete noob to hibernate, I just wonder if this is the proper way to do it? I'll appreciate any advice.

Answer 1

I think it is unnecessary to use Integer.valueOf(save.toString); because you know type of your identifier and Hibernate of course too. You can use (Integer)save .
