@SelectProvider should be applied to your Mapper interface. For example:
public interface MyMapper {
@Select("SELECT * FROM users")
User selectUsers();
}
The SelectProvider equivalent of this would be:
public interface MyMapper {
@SelectProvider(type=com.me.SomeHelperClass,method="getSelectAllUsersSQL")
User selectUsers();
}
public clas SomeHelperClass {
public String getSelectAllUsersSQL() {
return "SELECT * FROM users";
}
}
Cheers,
