第三步：创建/resources/springmvc.xml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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:kie="http://drools.org/schema/kie-spring"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://drools.org/schema/kie-spring
       http://drools.org/schema/kie-spring.xsd
       http://www.springframework.org/schema/mvc
	   http://www.springframework.org/schema/mvc/spring-mvc.xsd
	   http://www.springframework.org/schema/context
	   http://www.springframework.org/schema/context/spring-context.xsd">

    <kie:kmodule id="kmodule">
        <kie:kbase name="kbase" packages="rules">
            <kie:ksession name="ksession"></kie:ksession>
        </kie:kbase>
    </kie:kmodule>

    <bean class="org.kie.spring.annotations.KModuleAnnotationPostProcessor"/>

    <!--spring批量扫描-->
    <context:component-scan base-package="com.itheima" />
    <context:annotation-config/>
    <!--springMVC注解驱动-->
    <mvc:annotation-driven/>
</beans>

第四步：创建规则文件/resources/rules/helloworld.drl

package helloworld

rule "rule_helloworld"
    when
        eva l(true)
    then
        System.out.println("规则：rule_helloworld触发...");
end

第五步：创建RuleService

package com.itheima.service;

import org.kie.api.KieBase;
import org.kie.api.cdi.KBase;
import org.kie.api.runtime.KieSession;
import org.springframework.stereotype.Service;

@Service
public class RuleService {
    @KBase("kbase")
    private KieBase kieBase;
    public void rule(){
        KieSession kieSession = kieBase.newKieSession();
        kieSession.fireAllRules();
        kieSession.dispose();
    }
}

第六步：创建HelloController

package com.itheima.controller;

import com.itheima.service.RuleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/hello")
public class HelloController {
    @Autowired
    private RuleService ruleService;
    @RequestMapping("/rule")
    public String rule(){
        ruleService.rule();
        return "OK";
    }
}

7.3 Spring Boot整合Drools

目前在企业开发中Spring Boot已经成为主流，本小节我们来进行Spring Boot整合Drools。具体操作步骤：

第一步：创建maven工程drools_springboot并配置pom.xml
