* Viele zusätzliche Features (dank Starlette) wie:
    * **WebSockets**
    * extrem einfache Tests auf Basis von HTTPX und `pytest`
    * **CORS**
    * **Cookie-Sessions**
    * ... und mehr.

    try {
        super.close();
    } finally {
        // Don't release directory lease on close - it may be shared
        // Lease will be cleaned up by the lease manager
    }
}
```

### 5.2 Session Integration
```java
// In SmbSession.java
private DirectoryLeaseManager directoryLeaseManager;

public void initializeDirectoryLeasing() {
    if (context.getConfig().isUseDirectoryLeasing() && supports(SMB3_0)) {

この場合、レスポンスの送信が終わるまでデータベースセッションが保持されますが、使わないのであれば保持する必要はありません。

次のようになります:

{* ../../docs_src/dependencies/tutorial013_an_py310.py *}

終了コード、すなわち `Session` の自動クローズは:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[19:21] *}

...の部分で定義されており、遅いデータ送信が終わった後に実行されます:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[30:38] hl[31:33] *}

     *
     * Next is the response status line, followed by the number of HTTP response header lines,
     * followed by those lines.
     *
     * HTTPS responses also contain SSL session information. This begins with a blank line, and then
     * a line containing the cipher suite. Next is the length of the peer certificate chain. These

    Note over dep: Run code up to yield
    opt raise Exception
        dep -->> handler: Raise Exception
        handler -->> client: HTTP error response
    end
    dep ->> operation: Run dependency, e.g. DB session
    opt raise
        operation -->> dep: Raise Exception (e.g. HTTPException)
        opt handle
            dep -->> dep: Can catch exception, raise a new HTTPException, raise other exception
        end

* 通过 [Strawberry](https://strawberry.rocks) 等库进行 **GraphQL** 集成。
* 许多额外特性（归功于 Starlette），例如：
    * **WebSockets**
    * 基于 HTTPX 和 `pytest` 的极其简单的测试
    * **CORS**
    * **Cookie Sessions**
    * ……以及更多。
