*在这里，我们在路径操作函数*和依赖项中都使用着 SQLAlchemy 模型，它将与外部数据库进行通信。

这会需要一些“等待时间”。

但是由于 SQLAlchemy 不具有`await`直接使用的兼容性，因此类似于：

```Python
user = await db.query(User).first()
```

...相反，我们可以使用：

```Python
user = db.query(User).first()
```

然后我们应该声明*路径操作函数*和不带 的依赖关系`async def`，只需使用普通的`def`，如下：

```Python hl_lines="2"
@app.get("/users/{user_id}", response_model=schemas.User)

      synchronized (mutex) {
        return sortedSet(delegate().tailSet(fromElement), mutex);
      }
    }

    @Override
    public E first() {
      synchronized (mutex) {
        return delegate().first();
      }
    }

    @Override
    public E last() {
      synchronized (mutex) {
        return delegate().last();
      }
    }

      synchronized (mutex) {
        return sortedSet(delegate().tailSet(fromElement), mutex);
      }
    }

    @Override
    public E first() {
      synchronized (mutex) {
        return delegate().first();
      }
    }

    @Override
    public E last() {
      synchronized (mutex) {
        return delegate().last();
      }
