Mapper interfaces extending other interfaces

[Josh Kamau]

Hi team,

I have some mapper interfaces that have same methods. I want to put all the common methods in a generic interfaces so that all mapper interfaces will extend that interface. Does mybatis work that way ?

i have:
public interface BaseMapper<T> {
  public List<T> getList();
}

and
public interface UserMapper<User> {
   public List<User> getList();
}

Am using mybatis with mybatis-guice. Am asking this because refactoring this will break so much of the existing code. so i need to know in advance if this works

Kind regards.

Josh.

Hi Josh!!!
thanks for sharing a feature I wasn't aware :D

Anyway IIUC you meant

{code}
public interface BaseMapper<T> {

List<T> getList();

}
{code}

and

{code}
public interface UserMapper
extends BaseMapper<User> {
}
{code}

right?
TIA, have a nice day!!!

Yea, thats it Simo. And you dont have to repeat all those mapper interface methods.
