父pom中的代码

您使用哪个URL访问此文件？我正在使用本地端

@SpringBootApplication
@RestController
public class ABC extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(ABC.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(ABC.class, args);
    }

    @RequestMapping(value = "/")
    public String hello() {
        return "Hello World from Tomcat";
    }
}
