Jbpm流程管理实例（一）

 

准备工作：

下载jbpm-jpdl-suite-3.2.GA.zip和eclipse3.2（jbpm3不支持更高版本的eclipse）

解压jbpm-jpdl-suite-3.2.GA.zip，并把eclipse3.2解压覆盖jbpm-jpdl-suite-3.2.GA.zip中原来的eclipse文件夹。 

新建工程（java或web都可以，我们做测试建一个java工程） 

1、  安装JBPM插件到myeclipse工程项目中

- 引入Hibernate依赖包

- Junit (4.9)

- 引入JBPM依赖包（JBPM3）

* bsh.jar/ * jcr-1.0.jar/ * jbpm-identity.jar/ * jbpm-jpdl.jar

- 引入数据库驱动

* mysql-connector-java-3.1.13-bin.jar

2、定义相关配置文件

- Hibernate配置文件

* 提供hibernate配置文件（可以从jbpm-jpdl-3.2.GA\config\目录下拷贝，并修改其中的数据库连接设置即可）内容如下：

<?xml version="1.0" encoding="ISO-8859-1"?>

3、假设现在有一个公文，需要经过：张三、李四、王五的审批之后才能结束

定义流程文件：

双击运行jbpm工作流引擎：jbpm-jpdl-3.2.GA\designer\designer.bat，即打开eclipse3.2，不过这个eclipse中有jbpm插件。

（1）新建流程定义工程：

默认工程目录如下：

（2）在src/main/jpdl下可以新建流程定义：

（3）定义好了流程图如下：

生成代码如下：

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

<process-definition 
	xmlns="urn:jbpm.org:jpdl-3.2"
	name="文档测试流程">
   <start-state name="开始">
      <transition name="提交孙三审批" to="孙三审批"></transition>
   </start-state>
   <task-node name="孙三审批">
      <task name="审批1">
      	<assignment actor-id="ss"/>
      </task>
      <transition name="提交李四审批" to="李四审批"></transition>
   </task-node>
   <task-node name="李四审批">
      <task name="审批2">
      	<assignment actor-id="ls"/>
      </task>
      <transition name="提交周五审批" to="周五审批"></transition>
   </task-node>
   <task-node name="周五审批">
      <task name="审批3">
      	<assignment actor-id="zw"/>
      </task>
      <transition name="结束流程" to="结束"></transition>
   </task-node>
   <end-state name="结束"></end-state>
</process-definition>

4、  我们定义一个Document对象，及其hibernate映射，并将修改hibernate配置文件，将映射添加到其配置中（以便创建相应的数据库表）。

public class Document {
private int id;
		private String title;
		private String content;
		private String creator;
  		private Long processInstanceId; //流程实例id
		//getter/setter方法省略不写
}

其映射文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
  <class table="T_Document" name="com.dcy.jbpm.Document">
    <id name="id">
      <generator class="native"/>
    </id>
    <property name="title" />
    <property name="content" />
    <property name="creator" />
    <property name="processInstanceId" />
  </class>
</hibernate-mapping>
