3.配置类

基于springboot的初始化配置：

package com.drools.spring;

@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;

}

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 punctuation">}</span>

}

}

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