部署可以通过undeploy取消部署.
取消部署本身是异步的，所以如果想要在取消部署完成后通知，您可以部署指定完成处理程序:
vertx.undeploy(deploymentID, res -> { if (res.succeeded()) { System.out.println("Undeployed ok"); } else { System.out.println("Undeploy failed!"); }});
vertx.undeploy(deploymentID, res -> {
if (res.succeeded()) {
System.out.println("Undeployed ok");
} else {
System.out.println("Undeploy failed!");
}
});
