15.3 Usage Examples

Creating a Product

import plantpulse.api.v5.dto.request.ProductRequestV5;
import plantpulse.api.v5.dto.response.ProductResponseV5;

ProductRequestV5 req = new ProductRequestV5();
req.setProduct_id("PROD_A001");
req.setProduct_name("반도체 칩 A");
req.setSite_id("SITE_DJ");
req.setProduct_code("SKU-A001");
req.setCategory("반도체");
req.setUnit_of_measure("EA");
req.setExternal_product_id("ERP_P001");
req.setDescription("8nm 공정 반도체 칩");

ProductResponseV5 created = client.product().create(req);

Retrieval

ProductResponseV5 p = client.product().get("PROD_A001");
boolean exists      = client.product().exists("PROD_A001");
long total          = client.product().count();

Grouping by Category

import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;

Map<String, List<ProductResponseV5>> byCategory = client.product().list().stream()
        .collect(Collectors.groupingBy(ProductResponseV5::getCategory));

byCategory.forEach((cat, items) ->
    System.out.printf("%s: %d개%n", cat, items.size()));

Update / Delete

ProductRequestV5 update = new ProductRequestV5();
update.setProduct_id("PROD_A001");
update.setProduct_name("반도체 칩 A (v2)");
update.setSite_id("SITE_DJ");
update.setProduct_code("SKU-A001");
update.setUnit_of_measure("EA");
client.product().update("PROD_A001", update);
