推荐答案

我最近在 Bamboo AWS 中实现了这个功能插件;它是开源的，代码在 Bitbucket 上可用，你可以找到一个完整的示例如何启动/停止/重启EC2Task.java 中的一个实例(实际上应该是一个单独的类，唉......).

I've recently implemented this functionality within the Bamboo AWS Plugin; it's Open Source and the code is available on Bitbucket, you can find a complete example how to start/stop/reboot an instance within EC2Task.java (should be a separate class actually, alas ...).

幸运的是这一点都不复杂，例如，一个实例可以这样启动:

Fortunately this is not complicated at all, for example, an instance can be started like so:

private String startInstance(final String instanceId, AmazonEC2 ec2, final BuildLogger buildLogger)
        throws AmazonServiceException, AmazonClientException, InterruptedException
{
    StartInstancesRequest startRequest = new StartInstancesRequest().withInstanceIds(instanceId);
    StartInstancesResult startResult = ec2.startInstances(startRequest);
    List<InstanceStateChange> stateChangeList = startResult.getStartingInstances();
    buildLogger.addBuildLogEntry("Starting instance '" + instanceId + "':");

    // Wait for the instance to be started
    return waitForTransitionCompletion(stateChangeList, "running", ec2, instanceId, buildLogger); }

BuildLogger 是 Bamboo 特有的，并且 waitForTransitionCompletion() 是一个实现特定的帮助程序，用于报告流程/结果.AmazonEC2 ec2 参数将引用传递给 AmazonEC2Client 对象通过 AmazonEC2 接口，它定义了所有相关方法(以及许多其他方法)，特别是:

BuildLogger is Bamboo specific and waitForTransitionCompletion() is an implementation specific helper to report back on the process/result. The AmazonEC2 ec2 parameter passes the reference to an AmazonEC2Client object by means of the AmazonEC2 interface, which defines all relevant methods (amongst many others), specifically:

• StartInstances()
• StopInstances()
• 重启实例()
