//// tab | Pydantic v2

В Pydantic версии 2 вы будете использовать атрибут `model_config`, который принимает `dict`, как описано в <a href="https://docs.pydantic.dev/latest/api/config/" class="external-link" target="_blank">Документации Pydantic: Конфигурация</a>.

* 对被嵌入的模型也适用的编辑器支持（自动补全等）
* 数据转换
* 数据校验
* 自动生成文档

## 特殊的类型和校验

除了普通的单一值类型（如 `str`、`int`、`float` 等）外，你还可以使用从 `str` 继承的更复杂的单一值类型。

要了解所有的可用选项，请查看关于 <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">来自 Pydantic 的外部类型</a> 的文档。你将在下一章节中看到一些示例。

例如，在 `Image` 模型中我们有一个 `url` 字段，我们可以把它声明为 Pydantic 的 `HttpUrl`，而不是 `str`：

import static org.junit.jupiter.api.Assertions.assertFalse;
import static org.junit.jupiter.api.Assertions.assertNotNull;
import static org.junit.jupiter.api.Assertions.assertTrue;

/**
 * Tests {@code Dependency}.
 *
 */
class DependencyTest {

    @Test
    void testHashCodeNullSafe() {
        new Dependency().hashCode();
    }

    @Test
    void testEqualsNullSafe() {

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertFalse;
import static org.junit.jupiter.api.Assertions.assertNotNull;
import static org.junit.jupiter.api.Assertions.assertTrue;

/**

class DistributionManagementTest {

    @Test
    void testHashCodeNullSafe() {
        new DistributionManagement().hashCode();
    }
