java -jar target/Amsel-1.0-SNAPSHOT-jar-with-dependencies.jar

my Run.class with的入口点是以下

@SpringBootApplication
@ComponentScan("de.myapp")
public class Run {
    public static void main(String[] args) throws Exception{
        SpringApplication.run(Run.class, args);
    }
}

这是pom.xm l，用于生成jar

任何想法可能是什么问题？

好的，我自己找到了答案，当涉及到打包为jar文件时，springboot似乎有点不同，所以我不得不添加springboot-maven插件

http://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html
