- **Maven 3.6+** or **Gradle 7+** for build management
- **Optional**: SLF4J or Commons Logging for logging support

### Maven Dependency
```xml
<dependency>
    <groupId>org.codelibs</groupId>
    <artifactId>corelib</artifactId>
    <version>0.7.0</version>
</dependency>
```

### Gradle Dependency
```gradle
implementation 'org.codelibs:corelib:0.7.0'
```

## 📖 Usage Examples

### Bean Utilities
```java

并且，可以按需声明任意**深度**的子依赖项嵌套层级。

**FastAPI** 负责处理解析不同深度的子依赖项。

## 第一层依赖项 “dependable” { #first-dependency-dependable }

你可以创建一个第一层依赖项（“dependable”），如下：

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

这段代码声明了类型为 `str` 的可选查询参数 `q`，然后返回这个查询参数。

这个函数很简单（不过也没什么用），但却有助于让我们专注于了解子依赖项的工作方式。

## 第二层依赖项，“dependable”和“dependant” { #second-dependency-dependable-and-dependant }

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

First, import `OAuth2PasswordRequestForm`, and use it as a dependency with `Depends` in the *path operation* for `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` is a class dependency that declares a form body with:

* The `username`.
* The `password`.

    This will test if the module validator recognized that this dependency with classifier
    is not the same as the module itself.
