ProductRepository Interface
The ProductRepository interface extends from CrudRepository interface of Spring Data MongoDB that provides CRUD operations for an entity.
package demo.repositories;
import org.springframework.stereotype.Repository;
import org.springframework.data.repository.CrudRepository;
import demo.entities.Product;
@Repository("productRepository")
public interface ProductRepository extends CrudRepository<Product, String> {
}
Run Application
package demo.main;
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import demo.entities.Brand;
import demo.entities.Product;
import demo.repositories.ProductRepository;
public class Main {
public static void main(String[] args) {
try {
ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext(
"applicationContext.xml");
ProductRepository productRepository = (ProductRepository) applicationContext.getBean("productRepository");
Product product = new Product();
product.setName("Tivi 3");
product.setPrice(BigDecimal.valueOf(123));
product.setQuantity(4);
product.setStatus(true);
product.setDate(new Date());
product.setBrand(new Brand("5a30ec580867edfa45711677", "brand 3"));
product.setCategoryId("5a30de130867edfa4571166a");
List<String> colors = new ArrayList<String>();
colors.add("red");
colors.add("white");
colors.add("black");
product.setColors(colors);
product = productRepository.save(product);
System.out.println("Product Id Last Inserted: " + product.getId());
applicationContext.close();
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}
Output
Product Id Last Inserted: 5a586b2cf409b21b84030393
