java - Spring-Boot应用启动失败

Question

我已经使用 tomcat 容器创建了基本的 spring-boot 应用程序。使用 Maven 构建 jar 后，我将其作为 java -jar mybootapp-1.0.0.jar 运行。然后出现以下错误。我使用 mvn spring-boot:run 命令运行应用程序的任何方式，它运行良好。但是正常运行 jar 文件时出现错误的原因是什么。

如果你想在 tomcat 中部署 war，你需要在 pom.xml 文件中进行以下更改。

       1) In pom.xml file , make scope as provided for embedded server 

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-undertow</artifactId>
              <scope>provided</scope>
        </dependency>

         or

     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
     </dependency>

     2) In pom.xml file, make packaging as war

         <packaging>war</packaging>
