针对Helix Server后台管理系统在实际应用中表现出的配置选项复杂、操作繁琐、功能冗余等问题,提出了一种基于DOM树的Helix Server配置文件的裁剪方法,该方法先将配置文件转换为具有结构化树形特征的XML文件格式,再利用DOM解析器对配置文件重新编译,提取文件中的核心服务组件,在此基础上设计了新的Helix Server后台管理系统。使用结果表明,优化后的Helix Server性能稳定、功能实用,管理方便。 In view of the complex configuration options, cumbersome operation and redundant functions, the Helix Server back-end management system has been proposed to cut down the Helix Server configuration file based on the DOM tree. The method first converts the configuration file into XML file format with structured tree feature, re-compiles the configuration file by using DOM parser, extracts the core service components in the file, and designs a new Helix Server background management system. The results show that the optimized Helix Server is stable, functional and easy to manage.
