索引页不起作用，但api可在AWS beantalk Sprint Boot上使用

Question

我正在尝试将Spring Boot应用程序部署到AWS。

我通过application.properties将端口更改为5000现在， url/api/hello可以正常工作，但是url/不起作用

我收到白色标签错误。

package com.example.package-name;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan()
public class DemoApplication extends SpringBootServletInitializer {

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

的pom.xml

谁能告诉我该如何解决？ 主Starter文件有什么问题吗？

注意：本地一切正常，仅在AWS中加载错误页面而不是索引页面

Answer 1

我假设您在AWS Elastic beantalk Tomcat服务器中进行部署，请确保通过beantalk URL进行访问，这将在上载jar / war之后为您提供，通常空白错误会在您尝试访问错误的URL /错误的参数时给您，如果可能的话，请提供带有屏幕截图的详细信息。
