都会创建一个新的 `Settings` 对象，并且在创建时会再次读取 `.env` 文件。

如果依赖项函数是这样的：

```Python
def get_settings():
    return Settings()
```

我们就会为每个请求创建该对象，并为每个请求读取 `.env` 文件。 ⚠️

但由于我们在顶部使用了 `@lru_cache` 装饰器，`Settings` 对象只会在第一次调用时创建一次。 ✔️

{* ../../docs_src/settings/app03_an_py310/main.py hl[1,11] *}

接着，对于后续请求中依赖项里对 `get_settings()` 的任何调用，它不会再次执行 `get_settings()` 的内部代码并创建新的 `Settings` 对象，而是会一遍又一遍地返回第一次调用时返回的那个相同对象。
