Question

我使用hibernate ant工具生成带有注释的hibernate pojo类。使用ANT SCRIPT从现有表生成POJO类的策略是什么?

我找到答案了，我把它贴出来了。

Answer 1

If table column is having not null constraint, 
then a property related to that column in generated class will be of primitive type.
If table column is not having not null constraint, 
then a property related to that column in generated class will be of java.lang.X type.
(X == any of Integer,Byte,Float,Double depends on table column type in database)
If table column is having primary key constraint, 
then a property related to that column in generated class will be of primitive type.
If table column is having primary key constraint and it is AUTO INCREAMENT OR foreign key,
then a property related to that column in generated class will be of java.lang.X type.
(X == any of Integer,Byte,Float,Double depends on table column type in database)
