我是spring新手，我制作了graphql服务器，当我在本地运行它时，它可以正常工作。但是，当我构建.jar文件并尝试将其放入docker容器中时，总是会遇到以下异常：

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

这是我的文档：

FROM openjdk:11-jre-slim
EXPOSE 8085
ADD  GRQLOracle.jar GRQLOracle.jar
ENTRYPOINT ["java","-jar","/GRQLOracle.jar"]

主要类别：

import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class GrqlOracleApplication extends SpringBootServletInitializer {

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

有人知道我做错了什么吗？我试着用谷歌搜索类似的问题，但没有什么真正帮助我。
