我用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。然后发生了以下错误。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jar文件运行出错的原因是什么。

如果要在tomcat中部署war,则需要在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>

1.4.3.RELEASE目前似乎在镜子中缺失

仅进入1.4.2

由于tomcat服务器是spring boot应用程序的默认容器,因此您无需显式指定tomcat依赖项。我建议并强烈建议您使用Spring Initializer来启动Spring启动应用程序。
我可以知道,为什么您的应用程序类从SpringBootServletInitializer
延伸?您打算进行热部署吗?
