JBPM4.4 基本使用

JBPM工做流环境搭建：

                    一、先下载JBPM框架

                    二、安装JBPM图形编辑插件

                         注：插件在jbpm-4.4\install\src\gpd 目录下

 

建立工程导入JBPM依赖jar包

                     注：jar包目录jbpm-4.4\lib 单独使用JBPM开发 建议导入此目录下全部jar包

                      在src目录下建立JBPM持久化配置文件和注配置文件

                      一、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>

                    二、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操做流程

              注意：JBPM会在数据库建立18张表

public class Test extends TestCase { public void testdeploy() { ProcessEngine pEngine = Configuration.getProcessEngine(); RepositoryService repositoryService = pEngine.getRepositoryService(); // 部署流程
        String deploymentId = repositoryService.createDeployment().addResourceFromClasspath("test02.jpdl.xml").deploy(); // 删除流程 不会删除未完成任务得流程 // repositoryService.deleteDeployment(deploymentId); // 删除流程 会级联未完成任务得流程 // repositoryService.deleteDeploymentCascade(deploymentId);
 } // 获取对应人员任务
    public void testgetTask() { ProcessEngine pEngine = Configuration.getProcessEngine(); // 获取人工任务服务
        TaskService tService = pEngine.getTaskService(); // 经过assignee 提取全部任务 
        List<Task> tasks = tService.findPersonalTasks("李四"); Task task = tasks.get(0); System.out.println("任务数量------------->" + tasks.size()); System.out.println("任务名称------------->" + task.getActivityName()); System.out.println("任务人员-------------->" + task.getAssignee()); System.out.println("任务ID---------------->" + task.getId()); } // 查询当前流程所处阶段
    public void testgetCurrectactivity() { ProcessEngine pEngine = Configuration.getProcessEngine(); //获取执行服务
        ExecutionService eService = pEngine.getExecutionService(); //获取全部路程节点
        Set<String> activityName = eService.createProcessInstanceQuery().processInstanceId("test01.10001").uniqueResult().findActiveActivityNames(); Iterator<String> iterator = activityName.iterator(); while (iterator.hasNext()) { System.out.println(iterator.next()); } } // 完成任务
    public void testcoepleteTask() { ProcessEngine pEngine = Configuration.getProcessEngine(); //获取任务服务
        TaskService tService = pEngine.getTaskService(); tService.completeTask("20001"); } }

 

工做流基本操做:部署流程--》建立流程实例--》获取当前任务--》完成任务跳转下一个节点任务--》全部任务完成流程结束
