树莓派上做的ddns要自启动

sudo systemctl enable myddns.service  #设置开机自启动
sudo systemctl start  myddns.service    #开启服务
sudo systemctl  status  myddns.service   #查看服务是否正常运行
 
或者重启查看能否自启动。

[Standard_init_linux.go:190: exec user process caused “exec format error]

leokim / / 技术

You have to run the docker image that was built for a particular Architecture on a docker node that is running that same Architecture.

Take docker out of the picture for a moment. You can’t run a Linux application compiled and built on a Linux ARM machine and run it on a Linux amd64 machine. You can’t run a Linux application compiled and built on a Linux Power machine on a Linux amd64 machine.

I answered this same issue/question in this another post.
Take a look -> How much does Docker virtualize? 367

    public void setId(int id) {
        this.id = id;

        this.name = name;

    public Category getCategory(){
        return category;
    }
 
    public void setCategory(Category category){
        this.category = category;
    }
}

注解方式还可以更简单

1.applicationContext.xml去掉之前的配置,只用一行

1
<context:component-scan base-package="cn.leokim.pojo"/>

2.在Category上添加注解

1
2
@Component("c")
public class Category {

3.在product上添加注解

1
2
@Component("p")
public class Product {

运行出来结果是一样的
