问题How to start spring-boot app without depending on Database?解决了当mysql关闭时如何启动spring-boot应用程序。

是否可以对mongoDB进行相同的操作？

找不到Spring boot application properties中支持它的任何属性。

Spring-boot config

我得到以下stacktrace 

//Raw Image to Show Video Images [Assign from the Editor]
public RawImage image;
//Video To Play [Assign from the Editor]
public VideoClip videoToPlay;

private VideoPlayer videoPlayer;
private VideoSource videoSource;

//Audio
private AudioSource audioSource;

// Use this for initialization
void Start()
{
    Application.runInBackground = true;
    StartCoroutine(playVideo());
}

IEnumerator playVideo()
{
    //Add VideoPlayer to the GameObject
    videoPlayer = gameObject.AddComponent<VideoPlayer>();

    //Add AudioSource
    audioSource = gameObject.AddComponent<AudioSource>();

    //Disable Play on Awake for both Video and Audio
    videoPlayer.playOnAwake = false;
    audioSource.playOnAwake = false;

    //We want to play from video clip not from url
    videoPlayer.source = VideoSource.VideoClip;

    //Set video To Play then prepare Audio to prevent Buffering
    videoPlayer.clip = videoToPlay;
    videoPlayer.Prepare();

    //Wait until video is prepared
    while (!videoPlayer.isPrepared)
    {
        Debug.Log("Preparing Video");
        yield return null;
    }

    Debug.Log("Done Preparing Video");

    //Set Audio Output to AudioSource
    videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;

    videoPlayer.EnableAudioTrack(0, true);
    videoPlayer.SetTargetAudioSource(0, audioSource);

    //Assign the Texture from Video to RawImage to be displayed
    image.texture = videoPlayer.texture;

    //Play Video
    videoPlayer.Play();

    //Play Sound
    audioSource.Play();

    Debug.Log("Playing Video");
    while (videoPlayer.isPlaying)
    {
        Debug.LogWarning("Video Time: " + Mathf.FloorToInt((float)videoPlayer.time));

}

这是3年后的 ...但是现在有可能。

问题是启用了自动索引创建。使用Spring Boot 2.2，现在可以在启动时禁用并将所有必要的索引创建推迟到ApplicationReadyEvent侦听器。

您需要更改的特定属性是std::uniformn_distribution并进行设置 设置为false（将是将来版本的默认值）。

下面是ApplicationReadyEvent侦听器的示例，可以（而且应该！）代替它。
