springboot項目放到本地tomcat一直404

其實很簡單

@SpringBootApplication
public class GhostApplication extends SpringBootServletInitializer{

    public static void main(String[] args)

    {
        SpringApplication.run(GhostApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(GhostApplication.class);
    }
}

繼承SpringBootServletInitializer，覆蓋父類方法就可以了。成功解決
