Interface TypeMapper

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface TypeMapper

Maps a Java type to a SQL type. This is especially useful if you want to use vendor types.

The mapping defined by an instance of this class will be applied globally to all in and out parameter of all methods in an interface. If you want to customize only a single parameter use ParameterType, OutParameter.type() or ReturnValue.type() instead.

If no custom implementation is specified the following default are used:

default type mappings

Java Type	SQL type
String	Types.VARCHAR
char is not mapped
limited precision integers
Integer	Types.INTEGER
int	Types.INTEGER
Long	Types.BIGINT
