2.数据库

Flowable 默认使用 H2 数据库，但是可以通过修改配置文件来指定，本文使用的是 Postgres
创建一个名为 flowable 的库
Flowable 首次启动时默认会自动创建表
也可以通过官方SQL脚本手动创建表

在这里插入图片描述

3.资源文件

1.YML配置文件

  port: 8086
  servlet.context-path: /flowable-rest

2.Drools kbase

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

    <!--
        name: kbase 名称全局唯一
        packages: 规则文件包目录
        default: 指定为默认 kbase
    -->
    <kbase name="my_kbase" packages="processes.drools.*" default="true">
        <!--
            name: ksession 名称 kbase 下唯一
            default: 指定为默认 ksession
            clockType: 时钟类型 系统时钟或测试的伪时钟
        -->
        <ksession name="my_ks" clockType="realtime" default="true"/>
    </kbase>
</kmodule>

3.Drools rule

MyBusinessRule.drl

package drools

rule "myBusiness_1"
    when
    then
        System.out.println("Step4_1 drools 9.44.0.Final");
end

rule "myBusiness_2"
    when
    then
        System.out.println("Step4_2 drools 9.44.0.Final");
end

rule "myBusiness_3"
    when
    then
        System.out.println("Step4_3 drools 9.44.0.Final");
end

4.DMN 决策表

MyDecision.dmn.xml

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/DMN/20180521/MODEL/"
             id="simple" name="Simple" namespace="http://activiti.org/dmn">
