摘　　要：为提升全国水情信息交换的时效性,针对高峰期水情信息交换系统出现的数据入库滞时、统计停滞、系统崩溃等问题,提出多个线程并行处理、微化服务独立控制、多维文件交换统计等技术和方法,对系统信息发送、信息接收、统计分析、信息监控等四大核心层模块进行优化设计。基于核心模块服务微化,每个微服务下重构主次线程,部分线程交叉并行运行,并依据微服务和线程多维度构建文件交换统计模式,减少与数据库的直接交互,从而提升信息发送和接收、统计分析的效率,以及管理维护的友好性。2 a测试运行表明:水情信息交换系统应对大数据量交换能力大幅提升,发送和入库效率显著提高,早高峰基本无延时,可全力保障水情信息服务工作。In order to improve the exchange timeliness of national hydro-regime information,aiming at the problems of data storage delay,statistical stagnation,system crash and so on in the hydro-regime information exchange system during peak period,the technologies and methods of multi-thread parallel processing,independent control of micro service,multi-dimensional file exchange statistics and so on are proposed for optimization design of the four core layer modules of system information sending,information receiving,statistical analysis and information monitoring.Based on the core module service miniaturization,the primary and secondary threads are reconstructed under each micro service,and some threads run in parallel.According to micro service and multi-dimensional thread,file exchange statistics mode is constructed,which reduces the direct interaction with database,so as to improve the efficiency of information sending,receiving,and statistical analysis,and the friendliness of management and maintenance.The two-year test shows that the hydro-regime information exchange system greatly improves the large amount of data exchange ability,significantly improves the efficiency of sending and warehousing,basically has no data delay during morning peak,and fully guarantees the hydro-regime information service.
