无法 运行 Spring 在 IntelliJ 上使用 2.2.1.BUILD-SNAPSHOT 初始化
Unable to run Spring Initializr using 2.2.1.BUILD-SNAPSHOT on IntelliJ
试图在我的 j2ee 上刷机，所以下载了一个 Spring initializr 压缩文件夹并导入到 IntelliJ 中。
我在尝试 运行 作为 Java 应用程序时遇到错误。

有什么线索吗？
鉴于您的项目只是从 spring 初始化程序生成的，它实际上还没有做任何事情，您必须添加一些功能才能使其不立即退出。
如果您希望它以网络应用程序的形式启动，则必须添加对 spring-boot-starter-web.
的依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
如果您更喜欢 tomcat 作为您的容器，您可以使用上述依赖项，但如果您更喜欢其他东西 - 例如 jetty，您将不得不排除 tomcat 来自 spring-boot-starter-web

然后开始时你会得到接近这个的东西 运行 DemoApplication
