Drools如何使用规则流bpmn2

爱被打了一巴掌 2021-12-10 01:19 740阅读 0赞

最近项目用到了规则流踩了一些小坑，特以记录。  
代码写好了再放到规则文件中，规则流最好一步一步画，因为错了就给你抛看不懂没意义的异常。  
所有的包包括List这种都得引。  
我自己也一知半解，本文都是一些小细节，如有错漏，欢迎指正。  
1.文档  
官网：[https://www.drools.org/][https_www.drools.org]  
官方文档：[https://nheron.gitbooks.io/droolsonboarding/content/gettingStarted/drools.html][https_nheron.gitbooks.io_droolsonboarding_content_gettingStarted_drools.html] <-- lesson 4  
GitHub：[https://github.com/kiegroup/droolscourse][https_github.com_kiegroup_droolscourse]  
参考了很多人的博客 ，记不全了  
[https://blog.csdn.net/tian6318/article/details/78569388][https_blog.csdn.net_tian6318_article_details_78569388]  
[https://blog.csdn.net/wo541075754/article/category/6397798][https_blog.csdn.net_wo541075754_article_category_6397798]  
以前规则流是用Drools自己的.rf文件，现在用bpmn2 参考以下回答。  
[https://stackoverflow.com/questions/16698617/difference-between-rf-and-bpmn2][https_stackoverflow.com_questions_16698617_difference-between-rf-and-bpmn2]  
2.Intellj idea  
如果使用Intellj idea来使用drools到没有什么问题，bpmn打开很别扭啊，劝退劝退  
（1）官方视频 [https://screencast-o-matic.com/watch/cbfFXsX1gX][https_screencast-o-matic.com_watch_cbfFXsX1gX]  
过程就是安装jboss jpmn  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70]  
然后改打开方式  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 1]  
可是这样 全都堆在一起，看官方视频可能mac支持的好？

（2）如果用actiBPM ，倒是可以正常用，但是这查看xml和生成png的方式也是绝了。  
可以看这个 [https://blog.csdn.net/qq\_35463719/article/details/82967287][https_blog.csdn.net_qq_35463719_article_details_82967287]  
生成png： [https://blog.csdn.net/wk52525/article/details/79362904][https_blog.csdn.net_wk52525_article_details_79362904]

下面开始正文  
一. 安装  
可以参考https://blog.csdn.net/shenhaiwen/article/details/70230103  
我用的是eclipse mars，安装以下插件  
[https://download.jboss.org/drools/release/7.5.0.Final/org.drools.updatesite/][https_download.jboss.org_drools_release_7.5.0.Final_org.drools.updatesite]

二. 使用  
最简单的方式，建一个drool project 选带例子的 先了解一下大概的结构，就是有点旧。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 4]

三. 规则和规则流搭配使用  
按我自己的理解，规则流（bpmn2）里应该画一些“比较条件”，这些条件可能会变化，图像的形式更容易让人理解。  
规则（drl）里写一些固定的结果，比如说当某种情况下，执行某些行为 判断情况写在bpmn里 执行结果写在drl里  
（以下springboot工程）

建议先画一个只有开始结束的规则流，验证一下好不好使，再添加步骤。

(1) 新建drl  
![新建规则][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 8]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 9]  
注意包的引用 ！！！

package process
    import java.util.Calendar;
    import java.util.Date;
    import com.summer.my.droolsproject.Fact.PersonFact;
    
    rule "age-rule"
    	ruleflow-group "age-check-group"
        lock-on-active true
        when
            p:PersonFact()
        then
            System.out.println("hello"+p.getName());
            if(p.getBirthday()!=null){
        		int age =0;
        		Calendar now = Calendar.getInstance();
                now.setTime(new Date());
    
                Calendar birth = Calendar.getInstance();
                birth.setTime(p.getBirthday());
    
                if (birth.after(now)) {
                    age = 0;
                } else {
                    age = now.get(Calendar.YEAR) - birth.get(Calendar.YEAR);
                    if (now.get(Calendar.DAY_OF_YEAR) > birth.get(Calendar.DAY_OF_YEAR)) {
                        age += 1;
                    }
                }
               
                p.setAge(age);
        	}
    
    end
    
    rule "teenager-rule"
    	ruleflow-group "teenager"
        lock-on-active true
        when
            p:PersonFact()
        then
            System.out.println(p.getName()+"是一名青少年");
    end
    
    rule "adult-rule"
    	ruleflow-group "adult"
        lock-on-active true
        when
            p:PersonFact()
        then
            System.out.println(p.getName()+"是一名成年");
    end

(2) META-INF 文件夹 新建kmodule.xml

<?xml version="1.0" encoding="UTF-8"?>
    <kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
        <kbase name="process" packages="process">
            <ksession name="ksession-process"/>
        </kbase>
    </kmodule>

(3) 新建bpmn2 ？？用bpmn2建也行？标签不一样  
![新建规则流][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 10]

bpmn中的内容 有start 经过task  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 12][]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 13]  
箭头所指的部分要对应规则（drl）中的 ruleflow-group 指定执行的规则组  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 14]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 15]  
注意箭头选项，优先级，和condition的语言  
在规则流里用的类需要import  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdxaW5neXVlYmFpMTk_size_16_color_FFFFFF_t_70 16]  
AppTest 规则和流都放在process下，如果分开放是不是得指定上级的包啊，要不kSession的package定义多个包？

package com.summer.my.droolsproject;
    
    import org.apache.commons.lang3.time.DateUtils;
    import org.junit.Test;
    import org.kie.api.KieServices;
    import org.kie.api.runtime.KieContainer;
    import org.kie.api.runtime.KieSession;
    
    import com.summer.my.droolsproject.Fact.PersonFact;
    
    /**
     * Unit test for simple App.
     */
    public class AppTest{
    	@Test
    	public void testOne(){
    		try {
    	        KieServices ks = KieServices.Factory.get();
    	        KieContainer kContainer = ks.getKieClasspathContainer();
    	        KieSession kSession = kContainer.newKieSession("ksession-process");
    	        PersonFact person = new PersonFact();
    	        person.setName("李某某");
    	        person.setBirthday(DateUtils.parseDate("1999-01-01","yyyy-MM-dd"));
    	      
    	        kSession.insert(person);
    	        kSession.startProcess("process.myProcess");
    	        kSession.fireAllRules();  
    	        kSession.dispose();
    	        System.out.println(person.getName()+"的年龄是："+person.getAge());
    	    } catch (Throwable t) {
    	        t.printStackTrace();
    	    }
    	}
    	
    }

输出结果

以xml形式查看规则流
