jbpm-Api的简单使用

准备工作：开启mysql数据库服务并已生成jbpm数据库。

1、建立工程并在工程中建立工作流程，流程图如下：

流程定义的代码如下：

 

   

     

   

   

     

   

   

     

     

   

   

   

     

   

   

     

     

   

 

2、编写测试代码，如下：

package com.tc.test;

 

import java.util.Iterator;

import java.util.List;

 

import org.jbpm.api.Configuration;

import org.jbpm.api.ExecutionService;

import org.jbpm.api.HistoryService;

import org.jbpm.api.ProcessEngine;

import org.jbpm.api.ProcessInstance;

import org.jbpm.api.RepositoryService;

import org.jbpm.api.TaskService;

import org.jbpm.api.history.HistoryProcessInstance;

import org.jbpm.api.task.Task;

 

public class JbpmTest {

 

/**

* @param args

*/

public static void main(String[] args) {

//depaly();

//createExecute();

showHistory();

showExecution();

showTask();

}

/**

* 部署工作流程

*/

public static void depaly(){

ProcessEngine pe=new Configuration().buildProcessEngine();

RepositoryService rs=pe.getRepositoryService();

rs.createDeployment().addResourceFromClasspath("leaveHoliday.jpdl.xml").deploy();

 

}

/**

* 创建工作流程实例

*/

public static void createExecute(){

//leaveHoliday.170001  =null  null

//leaveHoliday-1

ProcessEngine pe=new Configuration().buildProcessEngine();

ExecutionService es=pe.getExecutionService();

ProcessInstance pi=es.startProcessInstanceByKey("leaveHoliday");

System.out.println("pi  id:"+pi.getId()+"  =key:"+pi.getKey()+"  name:"+pi.getName()+"  =ProcessDefinitionId:"+pi.getProcessDefinitionId());

}

/**

* 展示历史流程信息

*/

public static void showHistory(){

ProcessEngine pe=new Configuration().buildProcessEngine();

HistoryService hs=pe.getHistoryService();

 

//获取所有流程历史记录信息并输出

System.out.println("****************history********************");

List hiss=hs.createHistoryProcessInstanceQuery().list();

for (Iterator iterator = hiss.iterator(); iterator.hasNext();) {

HistoryProcessInstance historyProcessInstance = (HistoryProcessInstance) iterator

.next();

//null     =leaveHoliday-1       leaveHoliday.160001active

System.out.println("key:"+historyProcessInstance.getKey()+"      ProcessDefinitionId:"+historyProcessInstance.getProcessDefinitionId()

+"       ProcessInstanceId："+historyProcessInstance.getProcessInstanceId()+"   state:"+historyProcessInstance.getState());

}

}

/**

* 展示当前引擎中待处理流程

*/

public static void showExecution(){

ProcessEngine pe=new Configuration().buildProcessEngine();

ExecutionService es=pe.getExecutionService();

//获取某个特定的流程实例

ProcessInstance res=es.createProcessInstanceQuery().processInstanceId("leaveHoliday.170001").uniqueResult();

System.out.println("----------------------待执行的流程实例信息----------------------------");

List pl=es.createProcessInstanceQuery().list();

for (Iterator iterator = pl.iterator(); iterator.hasNext();) {

ProcessInstance processInstance = (ProcessInstance) iterator.next();

System.out.println("id:"+processInstance.getId()+"   key : "+processInstance.getKey()+"  name :"+processInstance.getName()

+"     ProcessDefinitionId："+processInstance.getProcessDefinitionId()+"      state:"+processInstance.getState());

}

}

/**

* 展示所有待处理任务信息

*/

public static void showTask(){

System.out.println("----------------------------task---------------------------------");

ProcessEngine pe=new Configuration().buildProcessEngine();

TaskService ts=pe.getTaskService();

//查找指定流程实例的任务

Task t=ts.createTaskQuery().processInstanceId("leaveHoliday.170001").uniqueResult();

System.out.println(t.getId()+":"+t.getName()+":"+t.getActivityName()+":"+t.getDescription()+":"+t.getExecutionId());

List ls=ts.createTaskQuery().list();

for (Iterator iterator = ls.iterator(); iterator.hasNext();) {

Task task = (Task) iterator.next();

System.out.println("id:"+task.getId()+"     name:"+task.getName()+"    getActivityName:"

+task.getActivityName()+"      getDescription:"+task.getDescription()+"      executionId:"+task.getExecutionId());

}

}

}
