这样就把依赖项“参数化”了，现在它内部带有属性 `checker.fixed_content` 的值 `"bar"`。

## 把实例作为依赖项 { #use-the-instance-as-a-dependency }

然后，我们可以在 `Depends(checker)` 中使用这个 `checker`，而不是 `Depends(FixedContentQueryChecker)`，因为依赖项是实例 `checker`，不是类本身。

解析依赖项时，**FastAPI** 会像这样调用 `checker`：

```Python
checker(q="somequery")
```

...并将其返回值作为依赖项的值，传给我们的*路径操作函数*中的参数 `fixed_content_included`：

### Exception Handling
```java
import org.codelibs.core.exception.*;

// Runtime exception wrappers eliminate try-catch boilerplate
try {
    // Code that might throw checked exceptions
    return ClassUtil.newInstance(className); // Wraps checked exceptions automatically
} catch (ClassNotFoundRuntimeException e) {
    // Handle the wrapped exception
    logger.error("Class not found: " + className, e);
}
```

    void mockInteraction_stubsThrow_andVerifiesInvocation() {
        // Arrange: Since SmbUnsupportedOperationException is a checked exception (extends IOException),
        // we need to use a method that can throw checked exceptions or wrap it in a RuntimeException
        @SuppressWarnings("unchecked")
        Supplier<String> supplier = mock(Supplier.class);
