Java 通过Vaadin应用程序启动springrestfulwebservice

我已经使用一个带有

@RestController

的类实现了一个Sping引导Maven项目。我将此应用程序配置为使用端口

9000

，就像普通的Vaadin应用程序使用端口8082一样。我想要实现的是，通过一个Vaadin应用程序项目类启动REST应用程序项目。Spring应用程序的主类称为

RestServiceApplication

，其中包含注释

@SpringBootApplication

。不，我只是打电话

SpringApplication sa = new SpringApplication(SenAalRestServiceApplication.class);
    sa.run(args);

运行RESTful Web服务

现在我的问题是，我不能调用REST服务中的任何方法。Spring启动的日志输出只是说：

编辑： 好的，我会更详细地解释： 我有两个申请： 1.Vaadin应用程序不是Spring驱动的，只是在普通的Tomcat容器（服务器）中运行。 2.包含主类和RestController的Spring引导应用程序

在项目1中。我有一个类，它只调用上面提到的

SpringApplication sa = new SpringApplication(SenAalRestServiceApplication.class);
    sa.run(args);

启动Vaadin应用程序并调用此代码片段后，Spring引导应用程序将启动，但它永远不会显示任何可用的REST服务。我认为目前Spring引导应用程序的日志输出太少。我使用了日志级别，但它仍然是一样的

现在我所做的是，删除了对项目2的依赖。ind项目1。并复制了项目2的所有来源。进入项目1。并尝试在项目1中直接运行Spring启动应用程序。我这里的问题是，嵌入式Tomcat服务器/容器无法启动。我得到以下错误。这里有什么问题？？？我正在使用前面提到的代码片段在Vaadin应用程序中启动Spring引导应用程序
