How do I make an abstract java standard DAO class to inherit in dao classes?

Apparently you'd like to implement a CrudRepository which is part of Spring Data, but is used as a strategy for persistent entities (JPA).

As you do not want to use any JPA provider, we move on to an alternative:

The Spring Data JDBC generic DAO implementation that seeks a generic, lightweight and simple approach to RDBMS, was based on the JdbcTemplate (Spring Framework) .

It delivers the complete implementation of the Spring PagingAndSortingRepository abstraction, without using JPA, XML.

public interface PagingAndSortingRepository<T, ID extends Serializable> extends CrudRepository<T, ID> {
             T  save(T entity);
    Iterable<T> save(Iterable<? extends T> entities);
             T  findOne(ID id);
        boolean exists(ID id);
    Iterable<T> findAll();
           long count();
           void delete(ID id);
           void delete(T entity);
           void delete(Iterable<? extends T> entities);
           void deleteAll();
    Iterable<T> findAll(Sort sort);
        Page<T> findAll(Pageable pageable);
    Iterable<T> findAll(Iterable<ID> ids);
}

Here's a usage reference:

Page<User> page = userRepository.findAll(
    new PageRequest(
        5, 10, 
        new Sort(
            new Order(DESC, "reputation"), 
            new Order(ASC, "user_name")
        )
    )
);

And a great subject with idealizer of the api Tomasz Nurkiewicz .
