摘　　要：随着计算机应用系统的飞速发展,应用环境、实现流程和组成模块日趋复杂,记录应用软件运行状态的日志功能越发重要。在分析了国际上主要日志系统功能的基础上,针对我们在开发大型遥感数据预处理系统过程中遇到的系统调试、过程追踪、状态记录等问题以及遥感数据处理的特点,提出并设计了一套完整的日志解决方案。该方案基于国际上通用的日志软件Log4J的系统架构,针对GHIPS系统特点,进行了必要的功能封装、数据库扩展等改进,设计了较为完整的适合GHIPS开发与运行要求的日志子系统。实验表明,该日志系统能够实现GHIPS所需的记录与追踪功能,同时可方便地实现日志的搜索、整理、报表生成等特殊要求。With the development of computer application system, the application environment, implement processes and composed modules are more and more complex, so the log function which can record the running states is more and more important. On the basis of analyzing the log systems on the international population, this paper has proposed a total solution on log, especially for GHIPS. Based on the infrastructure of Log4J, this solution improved some functions on encapsulation and database extension, and designed an entire log system which meets all the requirements of development and running for GHIPS. The experiment indicated, that the log system could meet all functional requirements of record and trace, and could implement some special function conveniently, such as search, arrangement and report generation by key words.
