drools6的kie-spring集成使用详解编程语言

一:使用maven导入jar包,在maven中央库http://search.maven.org/搜索kie-spring和drools

     <dependency>

         <groupId>org.drools</groupId>

         <artifactId>drools-core</artifactId>

         <version>6.3.0.Final</version>

     </dependency>

     <dependency>

         <groupId>org.kie</groupId>

         <artifactId>kie-spring</artifactId>

         <version>6.3.0. Final</version>

     </dependency>


二:新建spring-drools.xml配置文件

       <kie:kmodule id=”kmodule1″>

         <kie:kbase name=”kbase1″ packages=”drools.rules” ><!—父级和子级目录用 . –>

           <kie:ksession name=”ksession1″><!—这个kie:ksession可以不写 –>

                  <kie:consoleLogger/>

           </kie:ksession>

         </kie:kbase>

       </kie:kmodule>

       <bean id=”kiePostProcessor” class=”org.kie.spring.KModuleBeanFactoryPostProcessor”/>

注意：其中KModuleBeanFactoryPostProcessor这个bean一定得注解,

详细介绍请看https://docs.jboss.org/drools/release/6.1.0.Final/drools-docs/html/ch.kie.spring.html


三:写rules规则文件

package net.itxm

import net.itxm.DroolsTest.Message;

rule”Hello World”

    when

        m : Message( status == Message.HELLO, myMessage : message )

    then

        System.out.println( myMessage );

        m.setMessage( “Goodbye cruel world” );

        m.setStatus( Message.GOODBYE );

        update( m );

end

rule”GoodBye”

    when

        Message( status == Message.GOODBYE, myMessage : message )

    then

        System.out.println( myMessage );

end

因为不能贴项目代码,所以用helloworld,并且假设你们知道rules规则,

       不知道的请看http://docs.jboss.org/drools/release/6.3.0.Final/drools-docs/html/index.html


四:Junit4测试

在类名前加上注解

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(“classpath:drools/spring-drools.xml”)

注解该属性

@Autowired

private KieBase kbase;

       @Test

       publicvoid test(){

       KieSession kSession = kbase.newKieSession();

       //Object obj;一个赋值的java对象

       kSession.insert(obj);

       kSession.fireAllRules();

}

Main方法

@SuppressWarnings(“resource”)

publicstaticvoid main(String[] args) {

ClassPathXmlApplicationContext context =

new ClassPathXmlApplicationContext( “drools/spring-drools.xml” );

           //Object obj;一个赋值的java对象

StatefulKnowledgeSession kSession = (StatefulKnowledgeSession) context.getBean( “ksession1” );

    kSession.insert(obj);

    kSession.fireAllRules();

}


五:补充

rule”TOKEN A”

    salience 99

    agenda-group”TOKEN A”

    auto-focustrue

    when

       BrokerageBean( typeList.size() == 1 )

    then

       kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup(“TOKEN A1”).setFocus();//①

       kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup(“TOKEN A2”).setFocus();//②

end

rule”TOKEN A1″

    salience 99

    agenda-group”TOKEN A1″

    when

       $BB : BrokerageBean( $typeList : typeList )

       $TIB : TypesOfInsuranceBean( typeId == 1) from $typeList

       InsuranceBean( id == 3 ) from $TIB.insuranceList

       //exists ( $TIB : TypesOfInsuranceBean( typeId == 1) from $typeList

       //and InsuranceBean( id == 3 ) from $TIB.insuranceList )

    then

       DefaultDroolsRules.log.info(“执行TOKEN A1”);

       //$BB.setInsuranceRate(“32″,”0″,”0”);

       DefaultDroolsRules.setBb($BB,32,0);

end

rule”TOKEN A2″

    salience 99

    agenda-group”TOKEN A2″

    when

       $BB : BrokerageBean( $typeList : typeList )

       TypesOfInsuranceBean( typeId == 1) from $typeList

       //exists ( TypesOfInsuranceBean( typeId == 1) from $typeList )

    then

       DefaultDroolsRules.log.info(“执行TOKEN A2”);

       //$BB.setInsuranceRate(“24″,”0″,”0”);

       DefaultDroolsRules.setBb($BB,24,0);

End
