java - hibernate Ant 工具

Question

我已经使用 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？

我找到了答案并发布了它。

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.
