@SpringBootApplication

public class InitService extends SpringBootServletInitializer { 

    public static void main(String[] args) {
    SpringApplication.run("classpath:abc-server.xml", args);

这里我试图将Spring MVC项目迁移到带有嵌入式tomcat的Spring启动Standalone jar。所以我尝试加载现有项目中使用的上下文xml（abc-server.xml）。当我运行/部署spring boot jar时，抛出以下异常。

当您致电运行时，您只提供echo $this->getLayout()->createBlock('cms/block') ->setBlockId('idOfMyCmsPage') ->toHtml();作为应用程序配置的来源：

server-abc.xml

这意味着SpringApplication.run("classpath:abc-server.xml", args);被忽略，包括您已启用自动配置这一事实。如果没有打开自动配置，Spring Boot将不会自动为您配置嵌入式servlet容器。您需要同时提供InitService和InitService作为应用程序的配置。

我会向abc-server.xml提供InitService.class并使用SpringApplication.run来提取旧的XML配置：

@ImportResource

请注意，@SpringBootApplication @ImportResource("classpath:abc-server.xml") public class InitService { public static void main(String[] args) { SpringApplication.run(InitService.class, args); } }相当于@SpringBootApplication，@ComponentScan和@Configuration。您可以使用@EnableAutoConfiguration并删除其他三个注释，如上所述。

由于在run方法中加载上下文xml时缺少EmbeddedServletContainerFactory bean，因此无法启动EmbeddedWebApplicationContext
