如果你正在开发Spring Boot应用程序，请在主文件中添加“ SpringBootServletInitializer”，如以下代码所示。因为如果没有SpringBootServletInitializer，Tomcat会将其视为普通应用程序，则不会将其视为Spring引导应用程序。
@SpringBootApplicationpublic class DemoApplication extends *SpringBootServletInitializer*{ @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(DemoApplication .class); } public static void main(String[] args) { SpringApplication.run(DemoApplication .class, args); }}
