SpringBoot application可以運行，但是打war包，並且部署到Tomcat服務器，運行報錯404（springboot專屬404頁面） 原

application 

package com.allcam.fbs;

import javax.servlet.MultipartConfigElement;

@RestController

@SpringBootApplication(exclude={RedisAutoConfiguration.class,RedisRepositoriesAutoConfiguration.class})

@Configuration
public class Application  extends SpringBootServletInitializer

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


    @RequestMapping("/hello")
    public String index() {
        return "Hello World";
    }

    /**
     * 需要把web項目打成war包部署到外部tomcat運行時需要改變啓動方式
     */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

    /**

    @Bean
    public MultipartConfigElement multipartConfigElement()
    {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        // 單個數據大小
        factory.setMaxFileSize("1024MB");
        /// 總上傳數據大小
        factory.setMaxRequestSize("1024MB");

如果有servlet，還需要引入此jar包
