drool-6.5的自学demo

先丢代码地址

https://gitee.com/a247292980/drools

再丢pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.yy</groupId><artifactId>drools</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>drools Maven Webapp</name><url>http://maven.apache.org</url><properties><runtime.version>6.5.0.Final</runtime.version></properties><repositories><repository><id>jboss-public-repository-group</id><name>JBoss Public Repository Group</name><url>http://repository.jboss.org/nexus/content/groups/public/</url><releases><enabled>true</enabled><updatePolicy>never</updatePolicy></releases><snapshots><enabled>true</enabled><updatePolicy>daily</updatePolicy></snapshots></repository></repositories><dependencies><dependency><groupId>org.kie</groupId><artifactId>kie-api</artifactId><version>${runtime.version}</version></dependency><dependency><groupId>org.drools</groupId><artifactId>drools-core</artifactId><version>${runtime.version}</version></dependency><dependency><groupId>org.drools</groupId><artifactId>drools-decisiontables</artifactId><version>${runtime.version}</version></dependency><dependency><groupId>org.jbpm</groupId><artifactId>jbpm-test</artifactId><version>${runtime.version}</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency></dependencies>
</project>

 最后丢目录结构

 

 

老规矩要说的基本都在注释里面，想看的去看源码就好了，只说几个重要的

Message

pojo类

DecisionTableTest

drools使用xxx.xls的例子

public class DecisionTableTest {public static final void main(String[] args) {try {// load up the knowledge baseKieServices ks = KieServices.Factory.get();KieContainer kContainer = ks.getKieClasspathContainer();
//    	    写名字则取相应的ksession下的东西
//        	KieSession kSession = kContainer.newKieSession("ksession-dtables");
//            不写名字则全取了KieSession kSession = kContainer.newKieSession();// go !Message message = new Message();message.setMessage("Hello World");message.setStatus(Message.HELLO);kSession.insert(message);kSession.fireAllRules();} catch (Throwable t) {t.printStackTrace();}}}

 DroolsTest

drools操作xxxx.drl的例子

public class DroolsTest  {public static final void main(String[] args) {try {// load up the knowledge baseKieServices ks = KieServices.Factory.get();KieContainer kContainer = ks.getKieClasspathContainer();KieSession kSession = kContainer.newKieSession("ksession-rules");// go !Message message = new Message();message.setMessage("Hello World");message.setStatus(Message.HELLO);kSession.insert(message);kSession.fireAllRules();} catch (Throwable t) {t.printStackTrace();}}}

 ProcessTest

drools操作xxxx.bpmn的例子

public class ProcessTest {public static final void main(String[] args) {try {// load up the knowledge baseKieServices ks = KieServices.Factory.get();KieContainer kContainer = ks.getKieClasspathContainer();KieSession kSession = kContainer.newKieSession("ksession-process");// start a new process instancekSession.startProcess("com.sample.bpmn.hello");} catch (Throwable t) {t.printStackTrace();}}}

StatelessTest

用来区分StatelessKieSession和KieSession

public class StatelessTest {protected KieServices kieServices;protected KieContainer kieContainer;protected KieSession kieSession;protected StatelessKieSession statelessKieSession;@Beforepublic void init() {
//从Factory得到ServiceskieServices = KieServices.Factory.get();
//        在类路径中找到的所有DRL文件kieContainer = kieServices.getKieClasspathContainer();
//得到kmodule的ksessionkieSession = kieContainer.newKieSession("ksession-rules");
//stateless必须注释kmodule里全部的kbase
//		statelessKieSession=kieContainer.newStatelessKieSession();}//kieSession和statelessKieSession的调用是不一样的@Testpublic void testKieSession() {Message message = new Message();message.setMessage("Hello World");message.setStatus(Message.HELLO);kieSession.insert(message);kieSession.fireAllRules();}@Testpublic void testStatelessKieSession() {Message message = new Message();message.setMessage("Hello World");message.setStatus(Message.HELLO);statelessKieSession.execute(message);}
}

 kmodule.xml

<?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns="http://www.drools.org/xsd/kmodule"><!--<kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">--><!--name kbase的唯一标志packages 路径必须正确可少写可多写可不写不写的话放于根目录（不建议）ksession 的唯一标记--><!--<kbase name="rules" packages="Drools.rules">--><kbase name="rules" packages="rules"><!--<kbase name="rules" packages="">--><!--<kbase name="rules" packages="myrules">--><!--默认用最后一个--><!--<kbase name="rules" packages="rules,myrules">--><ksession name="ksession-rules"/></kbase><kbase name="dtables" packages="dtables"><ksession name="ksession-dtables"/></kbase><kbase name="process" packages="process"><ksession name="ksession-process"/></kbase>
