The problem with this approach is that the LogManager instance uses the system class loader to instantiate classes from the configuration file. 这种方法的问题是LogManager实例使用了系统类(SC)的装载程序从配置文件中对类进行实例化。
It uses the system class loader to achieve this. 它使用系统类(SC)装载程序来达到这个目的。
The specification of a Property element in the configuration file causes the setting of a new name-value property in the Properties table managed by the System class. 在配置文件中的Property元素规范导致在由System类管理的Properties表中设置新的名称-值属性(name-valueproperty)。
Mcl1 is a child of the system class loader, and mcl2 is a child of mcl1. mcl1是系统类(SC)装入器的孩子,mcl2是mcl1的孩子。
