The selection cannot be run on any server
提问by Sumit
I am trying to learn a bit about spring boot application. Below is the pom.xml file. The problem is that when I try to run the application on server I get the message The selection cannot be run on server. Not sure why this is happening.
我正在尝试了解一些有关 Spring Boot 应用程序的知识。下面是 pom.xml 文件。问题是，当我尝试在服务器上运行应用程序时，我收到了消息The selection cannot be run on server。不知道为什么会这样。
I have checked few similar stack overflow questions listed below "The selection cannot be run on any server"and Eclipse Maven Spring: Server Error when I try to Run As Server (Tomcat 7)but couldn't get a solution.
我检查了下面列出的几个类似的堆栈溢出问题 “选择不能在任何服务器上运行”和Eclipse Maven Spring：当我尝试作为服务器运行时的服务器错误 (Tomcat 7)但无法获得解决方案。
There are no errors or warnings in the problems tab of STS. Also I have configured STS to use Apache tomcat version 9.
STS 的问题选项卡中没有错误或警告。此外，我已将 STS 配置为使用 Apache tomcat 版本 9。

Taking a real stab in the dark as I can't try the code out myself at the moment, but it could be that you just need to run the file marked with @SpringBootApplication instead of looking for running via the server option. Thats how I normally do it, but I use Intellij so maybe its slightly different.
在黑暗中进行真正的尝试，因为我目前无法自己尝试代码，但可能是您只需要运行标有 @SpringBootApplication 的文件，而不是通过服务器选项寻找运行。这就是我通常的做法，但我使用 Intellij，所以可能略有不同。

Instead of Running the application as Java Application , Run the application as Spring Boot Application
不是将应用程序作为 Java 应用程序运行，而是将应用程序作为 Spring Boot 应用程序运行
