只有信息: Stopping service [Tomcat] 没有其他报错信息。如何排查。

抓取错误

实际上这个就是Java的main方法报错了，导致了tomcat停止了，只需要try catch下main方法的异常就能知道为什么停止了。

@SpringBootApplication  
@EnableScheduling  
public class DemoApplication {  
  
    public static void main(String[] args) {  
        try {  
            SpringApplication.run(DemoApplication.class, args);  
        } catch (Exception e) {  
            System.out.println("Application startup failed "+e.getMessage());  
        }  
    }  
  
}

没有加数据库驱动导致的。
