@SpringBootApplication

@Controller

public class DockerApplication {

public static void main(String[] args) {

SpringApplication.run(DockerApplication.class, args);

}

@RequestMapping("/user/find")

@ResponseBody

public Object findUser(){

Map<String, String > map = new HashMap<>();

map.put("name", "xdclass.net");

map.put("age","28");

return map;

}

}

由于harbor没有安装,无法把镜像推到私有镜像仓库上,所以先手动执行。

mvn install,然后把dockerfile和jar包放到一起
