如何从spring存储库插入（msyql）获取最后一个插入ID

Question

我想从spring web应用程序中获取插入mysql数据库中的'categoria'的id，这是我从spring开始的serviceImpl类。

package com.tomatubuk.Service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;    

import com.tomatubuk.Entidades.Categoria;
import com.tomatubuk.Repository.CategoryRepository;

@Service
public class CategoriaServiceImpl implements CategoriaService{

@Autowired
private CategoryRepository categoriarepository;

@Override
public Iterable<Categoria> ListAllCategoria() {
    return categoriarepository.findAll();
}

@Override
public Categoria saveCategoria(Categoria categoria){
    return categoriarepository.save(categoria);
}

@Override
public Iterable<Categoria> ListAllOrderASC() {
    return categoriarepository.findAllOrderASC();
}

@Override
public Iterable<Categoria> ListAllOrderDESC() {
    return categoriarepository.findAllOrderDESC();
}


}

这是我的catrgoria存储库，从我的serviceImpl类

调用

package com.tomatubuk.Repository;

import javax.transaction.Transactional;

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

import com.tomatubuk.Entidades.Categoria;

@Repository
@Transactional
public interface CategoryRepository extends CrudRepository<Categoria, 
Integer> {

@Query("Select c from Categoria c order by c.nombrecategoria asc")
public Iterable<Categoria> findAllOrderASC();

@Query("Select c from Categoria c order by c.nombrecategoria desc")
public Iterable<Categoria> findAllOrderDESC();

}

提前谢谢
