01-jbpm工作流实现

第一步：导入jbpm需要的jar包

第二步：导入需要的配置文件：jbpm.cfg.xml，jbpm.hibernate.cfg.xml，logging.properties

jbpm.hibernate.cfg.xml：

<?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>       <!-- 数据库信息 -->     <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>     <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>     <property name="hibernate.connection.url">jdbc:mysql:///jbpm_20130709?characterEncoding=utf8</property>     <property name="hibernate.connection.username">root</property>     <property name="hibernate.connection.password">root</property>         <!-- 其它信息 -->     <property name="hibernate.hbm2ddl.auto">update</property>     <property name="hibernate.format_sql">true</property>          <!-- 映射文件 -->     <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>

logging.properties：

handlers= java.util.logging.ConsoleHandlerredirect.commons.logging = enabledjava.util.logging.ConsoleHandler.level = SEVEREjava.util.logging.ConsoleHandler.formatter = org.jbpm.internal.log.LogFormatterorg.jbpm.level=SEVERE# org.jbpm.pvm.internal.tx.level=FINE# org.jbpm.pvm.internal.wire.level=FINE# org.jbpm.pvm.internal.util.level=FINE#org.hibernate.level=INFO#org.hibernate.cfg.SettingsFactory.level=SEVERE#org.hibernate.cfg.HbmBinder.level=SEVERE#org.hibernate.SQL.level=FINEST#org.hibernate.type.level=FINEST# org.hibernate.tool.hbm2ddl.SchemaExport.level=FINEST# org.hibernate.transaction.level=FINEST

jbpm.cfg.xml：

<?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>

java代码：

package cn.edu.zust.itee;import java.util.List;import org.jbpm.api.Configuration;import org.jbpm.api.ProcessEngine;import org.jbpm.api.task.Task;import org.junit.Test;/** * @author 郑勇 * 2013-07-09 10:43 */public class HelloWord {ProcessEngine processEngine = new Configuration().setResource("jbpm.cfg.xml").buildProcessEngine();//初始化：建表(创建18张)@Testpublic void createSchema(){new org.hibernate.cfg.Configuration().configure("jbpm.hibernate.cfg.xml").buildSessionFactory();}//一、部署流程定义(jbpm4_lob和jbpm4_deployment拥有数据)@Testpublic void deployProcessDefinition(){processEngine.getRepositoryService() .createDeployment() .addResourceFromClasspath("helloword/test.jpdl.xml") .addResourceFromClasspath("helloword/test.png") .deploy();}//二、启动流程定义(jbpm4_execution拥有数据)@Testpublic void startProcessInstance(){processEngine.getExecutionService().startProcessInstanceByKey("test");}//三、查询我的未办理的任务列表@Testpublic void findMyTaskList(){//查询任务String usrid = "员工";//String usrid = "部门经理";//String usrid = "总经理";List<Task> list = processEngine.getTaskService().findPersonalTasks(usrid);System.out.println("============="+usrid+"未办理的任务列表=============");//显示任务for(Task task:list){System.out.println("id="+task.getId()+",name="+task.getName()+",assignee="+task.getAssignee()+",createTime="+task.getCreateTime());}}//四、办理完成任务//id=10002//id=20001//id=30001@Testpublic void completeTask(){String userid = "30001";processEngine.getTaskService().completeTask(userid);}//任务全部执行完,表jbpm4_execution记录删除,jbpm4_hist_procinst表显示历史记录}

流程定义：

<?xml version="1.0" encoding="UTF-8"?><process name="test" xmlns="http://jbpm.org/4.4/jpdl">   <start g="37,3,48,48" name="start1">      <transition g="-52,-22" name="to 提交申请" to="提交申请"/>   </start>   <task assignee="员工" g="16,96,92,52" name="提交申请">      <transition g="-52,-22" name="to 部门经理审批" to="部门经理审批"/>   </task>   <task assignee="部门经理" g="16,180,92,52" name="部门经理审批">      <transition g="-52,-22" name="to 总经理审批" to="总经理审批"/>   </task>   <task assignee="总经理" g="16,264,92,52" name="总经理审批">      <transition g="-50,-22" name="to end1" to="end1"/>   </task>   <end g="38,348,48,48" name="end1"/></process>

Jbpm工作流活动介绍：

  1.预定义活动
  开始活动 Start
  结束活动 End   
  状态活动 State (cn.zust.edu.itee.state.ProcessStateActivity.java)
   
  任务活动 Task  (cn.edu.zust.itee.task.TaskVariable.java)
         个人 任务分配：
     *  1.使用流程变量： assignee="#{manager}" 在Expression设置#{manager}
        *  2.使用类处理AssignmentHandler :assignable.setAssignee(userId);
        *  3.TaskService.assignTask(taskId,userId);
  组任务活动分配      (cn.edu.zust.itee.groupTask.GroupTaskVariable.java)
*  1.使用流程变量： candidate-users="#{userIdsString}" 在Expression设置#{userIdsString}(String类型的变量，多用户用","分隔)
  *  2.使用类处理AssignmentHandler :assignable.addCandidateUser(userId);
  *  3.processEngine.getTaskService().addTaskParticipatingUser(taskId, userId, Participation.CANDIDATE);                
         
               判断活动 Decision  (cn.zust.edu.itee.decision.ProcessDecisionActivity.java)
        *  1.实现DecisionHandler接口
              
               分支/聚合        Fork/Join (cn.edu.zust.itee.joinFork.JoinFork.java)
    
    2.自定义活动  Custom
        * Custom活动 + ExternalActivityBehaviour接口
