RuleAgent Drools

沉默了，还是继续沉默。

 

原来一直使用的一种方式，今天才发现有一种其他的方式

代码：

 

package com.sample;

import org.drools.RuleBase;
import org.drools.StatefulSession;
import org.drools.agent.RuleAgent;

public class DirTest {

 /**
  * @param args
  */
 private static StatefulSession session;
 
 public static void main(String[] args) throws Exception {
  // TODO 自动生成方法存根
        //规则库
   RuleBase rulebase=loadRule();
 
      session=rulebase.newStatefulSession();
     
      session.fireAllRules();
  //工作记忆
  
 }
   
 //用代理Agent的方式读取规则
 private static RuleBase loadRule()throws Exception
 {
  RuleAgent agent=RuleAgent.newRuleAgent("/chen.properties");
  
  RuleBase ruleBase=agent.getRuleBase();
  
  return ruleBase;
 }
}

//properties文件

 

chen.properties文件

newInstance=true
dir=src/main/rules

 

规则文件：

#created on: 2009-5-28
package test

#list any import classes here.

 

#declare any global variables here

 

rule "Your First Rule"
 
 when
  #conditions
 then
  #actions
  System.out.println("你好！2009年5月28日22:36:37");
end

rule "Your Second Rule"
 #include attributes such as "salience" here...
 when
  #conditions
 then
  #actions
  
end

结果输出：

 

RuleAgent(default) INFO (Thu May 28 22:36:44 CST 2009): Configuring with newInstance=true, secondsToRefresh=-1
