我目前正在使用Spring编写API后端，我想使用Spring Boot部署到生产服务器上。
如果我在Eclipse中运行后端以编译为War（在Maven中指定），并使用Tomcat 7，则它可以正常运行。
但是，当我想部署到服务器时，我正在使用Spring Boot。

当我将整个项目复制到Linux服务器上并运行 maven package时 ，代码可以毫无问题地进行编译。然后，当我使用 java -jar [文件名] 运行生成的jar文件时，出现以下错误：

我认为问题是因为我没有运行正确的Spring / Spring Boot版本（也许它正在尝试使用不正确的Tomcat版本，所以该方法不存在？）
更新2015-04-06： 我尝试了kucing_terbang的使用spring boot v1.1.10的建议，但是现在得到如下错误：
[Stacktrace deleted, as out of space for stackoverflow question, refer to stacktrace of v1.1.12.RELEASE below]
更新2015-04-07： 然后我尝试使用v1.1.12.RELEASE给出类似错误：

然后，我再次尝试了mvn clean and mvn软件包，这使我在编译时遇到以下错误：

但是，如果我使用的是v1.2.3.RELEASE，则不会出现编译错误，然后如果我更改为v1.1.12.RELEASE，并在不进行清理的情况下运行mvn软件包，我也不会收到该错误（但我得到了像以前一样运行jar时出错）。
也许这表明存在更深的问题？
任何有关此问题的帮助将不胜感激。
谢谢！
我试图在本地PC上运行您的代码，但出现了类似您所在位置的错误。而且，这些是我删除这些错误的步骤。
更新Spring Boot版本
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.1.12.RELEASE</version>
更新您的主类，因为@SpringBootApplication注释仅在spring启动版本1.2.0之后存在
@SpringBootApplication
@Configuration
@EnableAutoConfiguration @ComponentScan public class Application { public static void main(String[] args) { ApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("NinjaSquare server up and running with Spring Boot!"); System.out.println("Let's inspect the beans provided by Spring Boot:"); String[] beanNames = ctx.getBeanDefinitionNames(); Arrays.sort(beanNames); for (String beanName : beanNames) { System.out.println(beanName); } }
}
webapp-runner从中删除“ ”依赖项，pom.xml因为该库还具有org.apache.catalina.core.StandardContext与嵌入式tomcat库中的类冲突的类。
webapp-runner
org.apache.catalina.core.StandardContext
<dependency> <groupId>com.github.jsimone</groupId> <artifactId>webapp-runner</artifactId> <version>${com.github.jsimone.version}</version> <scope>provided</scope>
是的，删除那些行;）
