无法执行./mvnw软件包&& java -jar target / gs-spring-boot-docker-0.1.0.jar

• 问答

我的代码基于 this example，但是当我执行./mvnw软件包&& java -jar target / docker-demo-0.0.1.jar时，我收到了失败消息。 注意：当我将DockerDemoApplication.java作为Java应用程序运行时，它成功在端口9199上运行

非常感谢您的帮助。

  1. 这是我的pom.xml 
lastErrorReportable

  1. 一个简单的应用程序类。

  2. 正在执行mvnw软件包&& java -jar target / docker-demo-0.0.1.jar，我正在关注。

    package com.desh.docker.dockerdemo;    
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class DockerDemoApplication {

    @RequestMapping("/")
    public String home() {
        return "Hello Docker World";
    }

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

}

  1. 我尝试通过清理.m2 \ repository \ org \ apache \ maven中的文件夹或添加commons-io-1.3.2.zip \ org \ apache \ commons \ io \ output \ DeferredFileOutputStream.class来尝试帮助
