Java Maven Spring启动应用程序卡住

我已经创建了一个示例Spring Boot应用程序，我可以在STS中使用RunAs Spring Boot App选项运行它。我还可以使用runasjunit选项运行Junit测试，而不会出现任何问题

但当我尝试使用Run as Maven Build选项用Maven打包我的应用程序时，应用程序总是在某个时刻卡住

我有下面一段代码在开始阶段

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}
@Override
public void run(String... args) throws Exception {
    Scanner scan = new Scanner(System.in);

    String name = scan.next();// It just stuck here especially when i use run as maven build

    Double balance = scan.nextDouble();
    Card card = new Card(name, balance);

    scan.close();

我的控制台好像卡在这里了

更新： 当我运行mvn spring boot:run时，它运行得很好。 但是如果我使用<代码> MVN清理安装Spring Bug：运行< /代码>，它就卡在中间了。

有什么帮助吗？

应用程序被卡住了，因为它正在等待

scan.next（）

方法调用中的输入数据

根据：

此方法在等待输入扫描时可能会阻塞，即使以前调用hasNext（）时返回true也是如此

似乎应用程序启动了，因为@NiVeR说应用程序的启动应该是正常的。你在期待什么？您向我们展示的代码具体位于何处，您从哪个类开始作为主类？main方法只是在我使用scan的地方调用Run方法。您可以看到更新的代码。检查scan（）的替代选项，然后在我选择作为“Spring Boot应用程序”运行或作为“JUNIT测试”运行时，为什么应用程序运行正常。只有当我以Maven Build的身份运行时，它才会卡住。
