没有未桥接的主机网络适配器
一般这种情况,打开VM的“编辑>>虚拟网络编辑器”,是没有“VMnet0”的,那么解决方法如下:
删除原有的“VMnet1”和“VMnet8”,再点击对话框左下方的“恢复默认设置”,重启电脑,再打开VM,即可像以前一样愉快的使用VM了。

mac管理员密码忘了怎么办?重置方法如下:
电脑开机,同时马上按住键盘上: command + R 键。(注意一定要在出现开机启动声之前按住)。否则无法正常进入 OS X 恢复功能。
大苹果进度条加载完成后,看最上方菜单,依次点击:实用工具 >> 终端
在终端中输入resetpassword
接下来等待弹窗出现,在弹窗中按要求重置密码即可。
注:如果不是苹果专用键盘,那么没有 command 键怎么办? win键=command键,即空格向左数第二个键,上面可能会画着一个windows标志。
如果是VM中安装的mac系统,重置mac密码的方法同上。
做了个Node项目,某个流程中最多五层回调进行逻辑判断,客户还要加一些业务,如果再这么做下去,至少还要加两层回调。就可读性来讲,是很差的。胃有点翻腾,要吐出来了…
在网上查了查,有很多人说Node的回调是个坑,但是个人还是愿意接受这不是Node坑的理论,回调这是Node的一个思想,我们既然选择了使用Node,就应该去分析、理解和适应它。
我相信无论遇到什么问题,总是能解决的。如果现在不能解决,那只是暂时没有想到解决办法而已。
一、generator(生成器)
是ES6标准引入的新的数据类型。一个generator看上去像一个函数,但可以返回多次。
我喜欢并在使用着这种方法,这种方法很优雅。
作用:一是同步流程控制Node回调;二是或以在外层获取回调函数内的返回值;三是如果逻辑判断层级很多,那么使代码的可读性更好; Continue reading
public:
具有最大的访问权限,可以访问任何一个在classpath下的类、接口、异常等。它往往用于对外的情况,也就是对象或类对外的一种接口的形式。
protected:
主要的作用就是用来保护子类的。它的含义在于子类可以用它修饰的成员,其他的不可以,它相当于传递给子类的一种继承的东西
default:
有时候也称为friendly,它是针对本包访问而设计的,任何处于本包下的类、接口、异常等,都可以相互访问,即使是父类没有用protected修饰的成员也可以。
private:
访问权限仅限于类的内部,是一种封装的体现,例如,大多数成员变量都是修饰符为private的,它们不希望被其他任何外部的类访问。
注意:java的访问控制是停留在编译层的,也就是它不会在.class文件中留下任何的痕迹,只在编译的时候进行访问控制的检查。其实,通过反射的手段,是可以访问任何包下任何类中的成员,例如,访问类的私有成员也是可能的。
区别:
public:可以被所有其他类所访问
private:只能被自己访问和修改
protected:自身、子类及同一个包中类可以访问
default:同一包中的类可以访问,声明时没有加修饰符,认为是friendly。
