Follows my class Cargodao and its interface.

package com.curso.boot.dao;

import org.springframework.stereotype.Repository;

import com.curso.boot.domain.Cargo;

@Repository
public class CargoDaoImpl extends AbstractDAO<Cargo, Long> implements CargoDAO {

}

Interface:

package com.curso.boot.dao;

import java.util.List;

import com.curso.boot.domain.Cargo;

public interface CargoDAO {

    void save(Cargo cargo);

    void update(Cargo cargo);

    void delete(Long id);

    Cargo findById(Long id);

    List<Cargo> findAll();
}

java.lang.ClassNotFoundException: javax.persistence.EntityManager: is sure it is in the classpath to javax.persistence-api?

Try taking your interface, in the 'Cargodao' section'

I’ve had a similar problem, see if in your abstract you’re like this:

private final Class<T> entityClass = (Class<T>) ((ParameterizedType)  getClass().getAnnotatedSuperclass()).getActualTypeArguments()[0`];

If you are trying using . getGenericSuperclass

private final Class<T> entityClass = (Class<T>) ((ParameterizedType)  getClass().getGenericSuperclass()).getActualTypeArguments()[0];

I think this will work.
