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=”

<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” class=”com.drools.demo.spring.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()
}
}
