3.配置类

基于springboot的初始化配置：

package com.drools.spring;

import org.kie.api.KieBase;

import java.io.IOException;

/**

*/


@Configuration


public class DroolsAutoConfiguration {

/** 特别要注意 rule的存放位置  */


private static final String RULES_PATH = "rules/";

@Bean


@ConditionalOnMissingBean(KieFileSystem.class)


public KieFileSystem kieFileSystem() throws IOException {


KieFileSystem kieFileSystem = getKieServices().newKieFileSystem();


for (Resource file : getRuleFiles()) {


String path = RULES_PATH + file.getFilename();


kieFileSystem.write(ResourceFactory.newClassPathResource(path, "UTF-8"));


}


return kieFileSystem;


}

/**

return resourcePatternResolver.getResources("classpath:" + RULES_PATH + "**/.");


}

@Bean


@ConditionalOnMissingBean(KieContainer.class)


public KieContainer kieContainer() throws IOException {


final KieRepository kieRepository = getKieServices().getRepository();

}
@Bean


@ConditionalOnMissingBean(KModuleBeanFactoryPostProcessor.class)


public KModuleBeanFactoryPostProcessor kiePostProcessor() {

}


}

4.Springboot启动类

package com.drools.spring;

import org.springframework.boot.SpringApplication;


import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
Created by lcc on 2018/9/27.


*/


@SpringBootApplication


public class SpringBootDroolsApplication {

public static void main(String[] args) {


SpringApplication.run(SpringBootDroolsApplication.class, args);


}


}

5.实体类

package com.drools.spring.entity;

import lombok.Data;

/**
Created by lcc on 2018/9/27.


*/


@Data


public class Address {

private String postcode;

private String street;

private String state;

}

6.规则返回结果类

package com.drools.spring.entity;

import lombok.Data;

/**
Created by lcc on 2018/9/27.


*/


@Data


public class AddressCheckResult {

private boolean postCodeResult = false; // true:通过校验；false：未通过校验


}

7.规则文件

注意存放的位置

package com.rules

import com.drools.spring.entity.Address;


import com.drools.spring.entity.AddressCheckResult;

rule "Postcode should be filled with exactly 5 numbers"
when

    address <span class="token operator">:</span> <span class="token function">Address</span><span class="token punctuation">(</span>postcode <span class="token operator">!=</span> null<span class="token punctuation">,</span> postcode matches <span class="token string">"([0-9]{5})"</span><span class="token punctuation">)</span>

    checkResult <span class="token operator">:</span> <span class="token function">AddressCheckResult</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

then

    checkResult<span class="token punctuation">.</span><span class="token function">setPostCodeResult</span><span class="token punctuation">(</span><span class="token boolean">true</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

    System<span class="token punctuation">.</span>out<span class="token punctuation">.</span><span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"规则中打印日志：校验通过!"</span><span class="token punctuation">)</span><span class="token punctuation">;</span>


end

8.规则文件kmodule

<?xml version="1.0" encoding="UTF-8" ?>

<kmodule xmlns="http://www.drools.org/xsd/kmodule">

    <kbase name="rules" packages="com.rules">

        <ksession name="ksession-rule"/>

    </kbase>

</kmodule>

9.测试Controller

package com.drools.spring.controller;

import com.drools.spring.entity.Address;


import com.drools.spring.entity.AddressCheckResult;


import org.kie.api.runtime.KieSession;


import org.springframework.stereotype.Controller;


import org.springframework.web.bind.annotation.RequestMapping;


import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;

/**
Created by lcc on 2018/9/27.


*/


@RequestMapping("/test")


@Controller


public class TestController {

@Resource


private KieSession kieSession;

@ResponseBody


@RequestMapping("/address")


public void test(){


Address address = new Address();


address.setPostcode("99425");
 AddressCheckResult result <span class="token operator">=</span> <span class="token keyword">new</span> <span class="token class-name">AddressCheckResult</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

 <span class="token keyword">int</span> ruleFiredCount <span class="token operator">=</span> kieSession<span class="token punctuation">.</span><span class="token function">fireAllRules</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

 System<span class="token punctuation">.</span>out<span class="token punctuation">.</span><span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"触发了"</span> <span class="token operator">+</span> ruleFiredCount <span class="token operator">+</span> <span class="token string">"条规则"</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

 <span class="token punctuation">}</span>


}


}

启动Springboot项目之后，默认访问http://localhost:8080/test/address 即可。

运行结果

规则中打印日志：校验通过!

触发了1条规则

规则校验通过
