如何在java中将OnStart脚本设置为CfnNotebookInstanceLifecycleConfigProps

Question

谷歌doid帮不了太多忙，sagemaker-1.121.0-sources.jar!/software/amazon/awscdk/services/sagemaker/CfnNotebookInstanceLifecycleConfigProps.java:102的亚马逊网络服务文档

  @software.amazon.jsii.Stability(software.amazon.jsii.Stability.Level.Stable)
    public Builder onStart(java.util.List<? extends java.lang.Object> onStart) {
        this.onStart = onStart;
        return this;
    }

问题是:如何在java中使用OnStart来传递OnStart脚本。我只是试着用CDK做similar的事情，而不是直接CloudFormation，结果卡住了。传递字符串列表(其中每一项都是一个bash命令)会导致异常。

提前感谢

使用CfnNotebookInstanceLifecycleConfig.NotebookInstanceLifecycleHookProperty

var lifeCycleOnStartHook = CfnNotebookInstanceLifecycleConfig.NotebookInstanceLifecycleHookProperty.builder()
                                                                                                     .content(
                                                                                                               Fn.base64(onStartCommand)
                                                                                                       )
                                                                                                       .build();
    var lcBuilder = CfnNotebookInstanceLifecycleConfigProps.builder()
                                                           .onStart(List.of(lifeCycleOnStartHook))
