Question

我正在尝试在办公室提供的tomcat服务器上部署Spring Boot应用程序。
我已经在嵌入式服务器（外部tomcat服务器9.13）上测试了该应用程序。我什至在heroku上进行了测试。
除了我办公室提供的服务器外，它都工作正常。但是我的jre版本与所提供的tomcat服务器相同。
有帮助吗？

我的jre版本：1.8.0_181
提供的tomcat服务器JVM版本：1.8.0_181-8u181-b13-2~deb9u1-b13

错误：

FAIL - Application at context path [/MotionFashion.B2B.Project-0.0.1-SNAPSHOT] could not be started
FAIL - Encountered exception [org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/MotionFashion.B2B.Project-0.0.1-SNAPSHOT]]]

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

    <artifactId>persistence-api</artifactId>
    <version>1.0.2</version>
    </dependency>

到
