摘　　要：声明式编程与传统的命令式编程相比是一种更简单、更快速的软件开发方式,但是支持声明式编程方式的引擎和工具很少。主要研究如何利用开源规则引擎Drools来实现JAVA的声明式编程的方法,着重分析声明式编程的特点以及规则引擎的结构、流程,核心的RETE算法和规则的匹配效率,并通过一个示例来分析如何高效率高性能的进行规则匹配和声明式编码。Declarative programming is a simpler and faster way of software development compared with traditional imperative programming, but the engines and tools supporting the declarative programming are not much. In this paper,the authors study the way of using open source rule engine Drools to realise JAVA declarative programming,the emphasis is put in analyzing the features of declarative programming as well as the structure and flow of rule engine, the core algorithm--RETE and the matching efficiency of rules, an example is utilised by the authors too to analyze how to perform high-efficiency rule-matching and declarative coding.
