我可以为Logger使用静态类吗? [英] Can I use static class for my Logger?

问题描述

最近我被告知静态类/方法是邪恶的.

Recently I have been told that static class/methods are evil.

以我的类Logger为例:

Take for example my class Logger:

class Logger{
   private static $logs = array();
   public static function add($msg){
      self::$logs[]=$msg;
   }

   public static function echo(){
       print_r(self::$logs);
   }
}

我可以随时在应用中使用这样的东西:

I can use whenever i want in my appliaction like this:

Logger::add('My log 1');

但是请阅读此开发人员:

But reading this developers:

• http://misko.hevery .com/2008/12/15/static-methods-are-death-to-testability/

该Logger类似乎不太好.

That Logger class doesn't seem so good.

所以:我可以静态使用它还是应该不惜一切代价避免使用它?

So: Can I use it statically or I should avoid it at any cost?

推荐答案

记录类是例外.

由于它们很少包含太多逻辑，因此您不必担心相同的测试问题.

Since they rarely contain much logic, you don't have the same testing concerns.

记录是使用静态类的一个好地方的完美示例.

Logging is a perfect example of a GOOD place to use static classes.

考虑其他选择:

• 日志对象的全局实例?
• 单例记录对象?
• 将日志记录对象传递给每个方法/类(通过构造函数)?

以上内容比使用static进行记录要糟糕得多.

The above are much worse than using static for logging.
