Map PostgreSql money data type to ORMLite

问题

What type of data I should define on my java model for PostgreSQL money type?

I know I could use BigDecimal, but it map to varchar(255) on PostgreSQL.

I think that @a_horse's comment provides some good information but I thought I'd add some additional ORMLite's specific details.

You could use ORMLite's BIG_DECIMAL_NUMERIC which will store it in Postgres as NUMERIC. You'll need to specify it as:

@DatabaseFiled(dataType = BIG_DECIMAL_NUMERIC)
BigDecimal number;

If you are set on using the money type, then you can define your own custom persister. You can date a look at the documentation that front:

There is also an example project with code which shows how to define a data persister for your custom type:
