初探Drools--java端使用

前言

本系列都是使用7.11版本

pom文件

初始化工具类

public class DroolsTest {

	private static DroolsTest singleton = new DroolsTest();
	
	private KieContainer KieContainer;
	
	private KieBase kieBasek;
	
	public static Map<String, String> map = new HashMap<String, String>();
	
	public KieContainer getKieContainer() {
		return KieContainer;
	}

	public void setKieContainer(KieContainer KieContainer) {
		this.KieContainer = KieContainer;
	}

	public static DroolsTest getSingleton() {
		return singleton;
	}

	public KieBase getKieBasek() {
		return kieBasek;
	}

	private void setKieBasek(KieBase kieBasek) {
		this.kieBasek = kieBasek;
	}
	
	private DroolsTest(){
		KieServices ks = KieServices.Factory.get();
		ReleaseId releaseId = ks.newReleaseId( "com.myspace", "ljlTest", "1.0.0" );
		KieContainer kContainer = ks.newKieContainer(releaseId);
		KieBase kieBase = kContainer.getKieBase();
		setKieBasek(kieBase);
		setKieContainer(kContainer);
		KieScanner kScanner = ks.newKieScanner( kContainer );
		kScanner.start( 10000L );
		
	}
}

调用

		DroolsTest drools = DroolsTest.getSingleton();
		KieSession kieSession = drools.getKieContainer().newKieSession();
		Map ruleMap = new HashMap();
		kieSession.setGlobal("RuleName", ruleMap);
		kieSession.fireAllRules();
		ruleMap = (Map) kieSession.getGlobal("RuleName");
		kieSession.dispose();
