### 運行

使用以下指令運行伺服器：

<div class="termy">

```console
$ uvicorn main:app --reload

- MinIO returns temp. S3 credentials associated to the found policy.

The returned credentials expiry after a certain period of time that can be configured via `&DurationSeconds=3600`. By default, the STS credentials are valid for 1 hour. The minimum expiration allowed is 15 minutes.

    /**
     * Default constructor.
     */
    public JobHelper() {
        // Default constructor
    }

    /** Monitor interval in seconds (default: 1 hour) */
    protected int monitorInterval = 60 * 60;// 1hour

    /** Thread-local storage for job runtime information */
    protected ThreadLocal<LaJobRuntime> jobRuntimeLocal = new ThreadLocal<>();
