如何使用drools和Spring整合详解编程语言

一、安装插件

grails install-plugin drools-gorm


二、引入相关的依赖jar包

加入drools-spring-5.2.0.Final.jar，drools-grid-impl-5.2.0.Final.jar


三、程序源码实例


1.conf/spring/resources.xml配置文件

?xml version= 1.0 encoding= UTF-8 ?

beans xmlns= http://www.springframework.org/schema/beans

  xmlns:xsi= http://www.w3.org/2001/XMLSchema-instance

  xsi:schemaLocation=

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

  import resource= drools.xml /

/beans


2.drools.xml配置文件

?xml version= 1.0 encoding= UTF-8 ?

beans xmlns= http://www.springframework.org/schema/beans

  xmlns:xsi= http://www.w3.org/2001/XMLSchema-instance

  xmlns:drools= http://drools.org/schema/drools-spring

  xsi:schemaLocation=

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

http://drools.org/schema/drools-spring http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-container/drools-spring/src/main/resources/org/drools/container/spring/drools-spring-1.0.0.xsd

  drools:kbase id= kBaseHelloWorld

  drools:resources

  ! 不是 drools:resource type= DRL source= classpath:com/jsptpd/rjy/zyj/service/Login.drl /

  drools:resource type= DRL source= classpath:drools/HelloWorld.drl /

  /drools:resources

  /drools:kbase

  ! 不能用这个，这样是单例，并发有问题

  ! drools:ksession id= kSessionHelloWorld type= stateful kbase= kBaseHelloWorld /

  bean id= droolsSpringDemo >
  property name= kBaseHelloWorld ref= kBaseHelloWorld /

  /bean

/beans


3.DroolsSpringDemo java代码实例

package com.drools.demo.spring

import com.drools.demo.main.Message

import org.drools.runtime.StatefulKnowledgeSession

class DroolsSpringDemo {

  def kBaseHelloWorld

  def helloWorld(){

  new Thread(new Runnable() {

  void run() {

  while (true){

  Thread.sleep(100)

  run()

  }

  }

  }) .start()

  new Thread(new Runnable() {

  void run() {

  while (true){

  Thread.sleep(76)

  run()

  }

  }

  }) .start()

  new Thread(new Runnable() {

  void run() {

  while (true){

  Thread.sleep(43)

  run()

  }

  }

  }) .start()

  while (true);

  }

  private run() {

  StatefulKnowledgeSession kstateful = kBaseHelloWorld.newStatefulKnowledgeSession()

  Message message = new Message();

  message.setMessage( Hello World );

  message.setStatus(Message.HELLO);

  kstateful.insert(message);

  kstateful.fireAllRules();

  kstateful.dispose();

  }

}


4.测试实例

class DemoDroolsSpringTest extends GroovyTestCase{

  def droolsSpringDemo

  public void testSomething() {

  droolsSpringDemo.helloWorld()

  }

}
