ruleengine's Introduction

ruleEngine

可视化配置规则引擎

ui

框架

后端

采用spring cloud微服务架构

前端

vue

npm install
npm run dev

规则引擎

采用drool规则引擎

drool

将变量值放入hashmap，当作drool的输入fact

自定义dsl语法

[when][]lt = <
[when][]le = <=
[when][]ge = >=
[when][]gt = >
[when][]eq = ==
[when][]ne = !=
[when][]and = &&
[when][]or = ||
[when][]contains = contains
[when][]notcontains = not contains
[when]input {field:[\w\.]+} = {field}()
[when]- {field:[\w\.]+} {operator} {value:.+} = {field} {operator} {value}
[when]resultInit = $ruleResult:RuleResult()
[then]result=$ruleResult.addRuleHit(drools.getRule().getName())

输入dsrl（业务人员编写的规则）

rule "test" 
when 
resultInit 
input 
- this["sex"] >= 1 
then result ;
end
rule "test2" 
when 
resultInit 
input 
- this["sex"] > 2  and  this["age"] < 12 
then result ;
end

输出drl

package xyz.sally.core.rules.uuiddcfdc76b4ed24e0a9bd79a86424fc903

import xyz.sally.core.fact.*
import xyz.sally.core.po.*
import java.util.HashMap;
import java.util.Map;rule "test" 
when 
$ruleResult:RuleResult() 
$map:HashMap(this["sex"]  >=  1) 
then $ruleResult.hitRule(drools.getRule().getName()) ;
end
rule "test2" 
when 
$ruleResult:RuleResult() 
$map:HashMap(this["sex"] > 2  &&  this["age"]  <  12) 
then 
System.out.println($map);
$ruleResult.hitRule(drools.getRule().getName()) ;
end
