public final class ClassUtility
extends Object

Title: 常用代码打包

Description: A utility class to assist with loading classes by name. Many application servers use custom classloaders, which will break uses of:

    Class.forName(className);
 

This utility attempts to load the class using a number of different mechanisms to work around this problem.
