摘　　要：Java虚拟机(JVM)中的类加载机制可以在Java应用程序运行期间动态加载类文件,而不影响其它功能模块的正常运行.通过对Java类加载器的层次体系结构,动态类加载机制原理、实现过程进行分析,将Java动态类加载机制应用到高校网站管理平台的文件发布模块中,使得设计好的静态网页和后台管理系统相关联,通过自定义加载器来加载加密过的Java类文件.这样以可插拔的方式快速的部署二级网站,增强了网站管理平台的灵活性和可扩展性.In order to load Java class file during the Java application runtime and without affecting the normal operation of other functional modules, the realization of Java dynamic class loading method is given based on the java virtual machine （JVM） mechanism. Java Class Loader architecture, theory of dynamic class loading mechanism, the implementation process are analyzed, and which are applied to the file release module of web site management platform system. The file release module is designed to make static web pages and website management system linked. Through the custom loader to loading encryption of Java class files. In a hot swap way to implement the deployment of secondary website, enhance the site management platform＇s flexibility and expansibility.
