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

* The `username`.
* The `password`.
* An optional `scope` field as a big string, composed of strings separated by spaces.
* An optional `grant_type`.

/// tip

The OAuth2 spec actually *requires* a field `grant_type` with a fixed value of `password`, but `OAuth2PasswordRequestForm` doesn't enforce it.

### Beispieltools zur Ausführung beim Hochfahren { #example-tools-to-run-at-startup }

Einige Beispiele für Tools, die diese Aufgabe übernehmen können, sind:

* Docker
* Kubernetes
* Docker Compose
* Docker im Schwarm-Modus
* Systemd
* Supervisor
* Es wird intern von einem Cloudanbieter im Rahmen seiner Dienste verwaltet
* Andere ...

In den nächsten Kapiteln werde ich Ihnen konkretere Beispiele geben.

### Example Tools to Run at Startup { #example-tools-to-run-at-startup }

Some examples of the tools that can do this job are:

* Docker
* Kubernetes
* Docker Compose
* Docker in Swarm Mode
* Systemd
* Supervisor
* Handled internally by a cloud provider as part of their services
* Others...

I'll give you more concrete examples in the next chapters.

The API docs use **Swagger UI** and **ReDoc**, and each of those need some JavaScript and CSS files.

By default, those files are served from a <abbr title="Content Delivery Network: A service, normally composed of several servers, that provides static files, like JavaScript and CSS. It's commonly used to serve those files from the server closer to the client, improving performance.">CDN</abbr>.

    e.execute(runMe);
    fakePool.runAll();

    assertEquals(2, numCalls.get());
  }

  public void testInterrupt_beforeRunRestoresInterruption() throws Exception {
    // Run a task on the composed Executor that interrupts its thread (i.e. this thread).
    fakePool.execute(() -> Thread.currentThread().interrupt());
    // Run a task that expects that it is not interrupted while it is running.

        if (configuratorConfig != null) {
            mojo.setComponentConfigurator(configuratorConfig.getValue());
        }

        PlexusConfiguration composerConfig = c.getChild("composer");

        if (composerConfig != null) {
            mojo.setComponentComposer(composerConfig.getValue());
        }

        String since = c.getChild("since").getValue();

        if (since != null) {

### 獨立程式 { #separate-program }

為了達成這點，你通常會有一個「獨立的程式」來確保你的應用在開機時會被啟動。很多情況下，它也會確保其他元件或應用一併啟動，例如資料庫。

### 開機自動啟動的工具範例 { #example-tools-to-run-at-startup }

能做到這件事的工具包括：

- Docker
- Kubernetes
- Docker Compose
- Docker 的 Swarm 模式
- Systemd
- Supervisor
- 由雲端供應商在其服務內部處理
- 其他...

我會在後續章節給出更具體的例子。

## 重新啟動 { #restarts }

和確保你的應用在開機時會執行一樣，你大概也會希望在發生失敗之後，它能「自動重新啟動」。
