商品dao+service

新建ProductInfo

@Entity
@Data
public class ProductInfo {

    /** 商品id. */
    @Id
    private String productId;

    /** 商品名称. */
    private String productName;

    /** 单价. */
    private BigDecimal productPrice;

    /** 库存. */
    private  Integer productStock;

    /** 描述. */
    private String productDescription;

    /** 小图. */
    private String productIcon;

    /** 商品状态,0正常1下架. */
    private Integer productStatus;

    /** 类目编号. */
    private Integer categoryType;

建立ProductInfoRepository

public interface ProductInfoRepository extends JpaRepository<ProductInfo,String> {
    List<ProductInfo> findByProductStatus(Integer productStatus);
}

对接口测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class ProductInfoRepositoryTest {

    @Autowired
    private ProductInfoRepository repository;

    @Test
    public void save(){
        ProductInfo productInfo = new ProductInfo();
        productInfo.setProductId("123456");
        productInfo.setProductName("皮蛋粥");
        productInfo.setProductPrice(new BigDecimal(3.2));
        productInfo.setProductStock(4);
        productInfo.setProductDescription("很好喝的粥");
        productInfo.setProductIcon("http://xxxx.com");
        productInfo.setProductStatus(0);
        productInfo.setCategoryType(3);
        ProductInfo result = repository.save(productInfo);
        Assert.assertNotNull(result);
    }

    @Test
    public void findByProductStatus() {
        List<ProductInfo> productInfoList= repository.findByProductStatus(0);
        Assert.assertEquals(1,productInfoList.size());
    }
}

service层

ProductService：

public interface ProductService {
    ProductInfo findOne(String productId);

    /** 查询所有在架商品 */
    List<ProductInfo> findUpAll();

    Page<ProductInfo> findAll(Pageable pageable);

    ProductInfo save(ProductInfo productInfo);

    //加库存

    //减库存
}

ProductServiceImpl:

@Service
public class ProductServiceImpl implements ProductService {

    @Autowired
    private ProductInfoRepository repository;

    @Override
    public ProductInfo findOne(String productId) {
        return repository.findById(productId).get();
    }

    @Override
    public List<ProductInfo> findUpAll() {
        List<ProductInfo> productInfoList = repository.findByProductStatus(ProductStatusEnum.UP.getCode());
        return productInfoList;
    }

    @Override
    public Page<ProductInfo> findAll(Pageable pageable) {
        return repository.findAll(pageable);
    }

    @Override
    public ProductInfo save(ProductInfo productInfo) {
        return repository.save(productInfo);
    }
}

对service测试：

@RunWith(SpringRunner.class)
@SpringBootTest
public class ProductServiceImplTest {

    @Autowired
    private ProductServiceImpl productService;

    @Test
    public void findOne() {
        ProductInfo productInfo = productService.findOne("1001");
        Assert.assertEquals("皮皮虾",productInfo.getProductName());
    }

    @Test
    public void findUpAll() {
        List<ProductInfo> productInfoList = productService.findUpAll();
        Assert.assertNotEquals(0,productInfoList.size());
    }

    @Test
    public void findAll() {
        PageRequest request = new PageRequest(0,2);
        Page<ProductInfo> productInfoPage = productService.findAll(request);
        //System.out.println(productInfoPage.getTotalElements());
        Assert.assertNotEquals(0,productInfoPage.getTotalElements());
    }

    @Test
    public void save() {
        ProductInfo productInfo = new ProductInfo();
        productInfo.setProductId("1001");
        productInfo.setProductName("皮皮虾");
        productInfo.setProductStatus(ProductStatusEnum.DOWN.getCode());
        productInfo.setProductDescription("很好吃的虾");
        productInfo.setProductStock(90);
        productInfo.setProductPrice(new BigDecimal(4.56));
        productInfo.setProductIcon("http://xxxx.jpg");
        productInfo.setCategoryType(4);
        ProductInfo result = productService.save(productInfo);
        Assert.assertNotNull(result);
    }
}
