JBPM4.4 基本使用

JBPM工作流环境搭建：

1、先下载JBPM框架

2、安装JBPM图形编辑插件

注：插件在jbpm-4.4installsrcgpd 目录下

创建工程导入JBPM依赖jar包

注：jar包目录jbpm-4.4lib 单独使用JBPM开发建议导入此目录下所有jar包

在src目录下创建JBPM持久化配置文件和注配置文件

1、jbpm.cfg.xml 默认配置文件

<?xml version="1.0" encoding="UTF-8"?>

<jbpm-configuration>

  <import resource="jbpm.default.cfg.xml" />
  <import resource="jbpm.businesscalendar.cfg.xml" />
  <import resource="jbpm.tx.hibernate.cfg.xml" />
  <import resource="jbpm.jpdl.cfg.xml" />
  <import resource="jbpm.bpmn.cfg.xml" />
  <import resource="jbpm.identity.cfg.xml" />

  <!-- Job executor is excluded for running the example test cases. -->
  <!-- To enable timers and messages in production use, this should be included. -->
  <!--
  <import resource="jbpm.jobexecutor.cfg.xml" />
  -->

</jbpm-configuration>

2、jbpm.hibernate.cfg.xml 数据库持久化配置文件示例为Mysql 数据库

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpm?useUnicode=true&amp;characterEncoding=UTF-8</property>
        <property name="hibernate.connection.username">jbpm</property>
        <property name="hibernate.connection.password">jbpm</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <property name="hibernate.format_sql">true</property>

        <mapping resource="jbpm.repository.hbm.xml" />
        <mapping resource="jbpm.execution.hbm.xml" />
        <mapping resource="jbpm.history.hbm.xml" />
        <mapping resource="jbpm.task.hbm.xml" />
        <mapping resource="jbpm.identity.hbm.xml" />

    </session-factory>
</hibernate-configuration>

绘制流程图 test01.jpdl.xml 流程图为.jpdl.xml 结尾如何绘制流程省略

调用API操作流程

注意：JBPM会在数据库创建18张表

工作流基本操作:部署流程--》创建流程实例--》获取当前任务--》完成任务跳转下一个节点任务--》所有任务完成流程结束
