This is demonstrated using the ExceptionHandler class, which again adopts a singleton design pattern.
使用exceptionhandler类可以展示这一点，该类也采用了singleton设计模式。
A global (static global) instance of ExceptionHandler should be defined prior to the definition of the actual global (static global) variable in question.
应该在定义有问题的实际全局(静态全局)变量之前定义ExceptionHandler的全局(静态全局)实例。
