如何从Drools Rule调用jbpm进程? [英] how to call jbpm process from Drools Rule?

问题描述

我的要求是，先触发第二条规则，然后停止该过程，而不触发第三条规则

My requirement is,Fire 2nd rule then stop the process without firing 3rd rule

在jBPM流程的中间，使用RuleFlow组(包含3个规则)并触发第一个规则并完成该规则，然后将控制权交给jBPM流程，然后再次触发第2个规则继续执行jB [M流程，依此类推. ...那怎么办呢?

In the middle of jBPM process by using RuleFlow group(contains 3 rules) and fire the 1st rule and completed that rule then give the control to jBPM process and then fire 2nd rule again continue the jB[M process and so on....so how could it will be done ?

例如:

规则"Paycheck"

rule "Paycheck"

ruleflow-group "Order_flow"
when
    $process: WorkflowProcessInstance()

    OrderDetails(price<=1000)from $process.getVariable("orderDetails")

then 

    System.out.println("****** This is Paycheck  from rule ******\n");
    $process.setVariable("price", 2000);

结束

开始---> workflowProcessInstance(数据可在kcontext中获得)---> ruleflowgroup(具有3条规则)----> Fire 1st规则---> paycheck(脚本任务)----> Fire 2nd规则--->欺诈检查(脚本任务)->触发第三条规则---->库存检查(脚本任务)---->结束

start ---> workflowProcessInstance(data available in kcontext)--->ruleflowgroup(with 3 rules)---->Fire 1st rule --->paycheck(Script task)---->Fire 2nd rule --->Fraudcheck(Script task)-->Fire 3rd rule---->inventorycheck(Script task)----> end

推荐答案

您无法告诉规则引擎要触发哪个规则，该引擎将根据激活的RuleFlowGroup和会话中的数据来决定要触发的规则.

You cannot tell the rule engine which rule to fire, the engine will decide what to fire based on the RuleFlowGroup active and the data that is inside the session.
