JBPM4.4 使用之流程管理初探

注:本篇只做简略的入门样例,更深入的介绍,请关注之后的博客内容。

 

管理流程定义

主要功能包括:

-发布流程定义

-查看流程定义

-删除流程定义

import java.util.List;

import org.jbpm.api.Configuration;
import org.jbpm.api.ProcessDefinition;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.RepositoryService;

import junit.framework.TestCase;


public class HelloTest extends TestCase {
	
	ProcessEngine processEngine;	
	
	public HelloTest() {
		processEngine = Configuration.getProcessEngine();
	}
	
	public void testDeploy(){
		RepositoryService rs = processEngine.getRepositoryService();
		
		//发布流程定义
		String deploymentId=rs.createDeployment().
		addResourceFromClasspath("helloworld.jpdl.xml").deploy();
		
		//获得流程定义		
		List<ProcessDefinition> list=rs.createProcessDefinitionQuery().list();
		System.out.println("list.size():"+list.size());
		for (ProcessDefinition pd : list) {
			System.out.println("pd.id:"+pd.getId());
		}
		
		System.out.println("deploymentId:"+deploymentId);
		//删除流程定义
		rs.deleteDeploymentCascade(deploymentId);
		//删除后查询流程定义
		System.out.println("after del list count:"+
				rs.createProcessDefinitionQuery().list().size());			
		
	}
}

 

 

完成后点击右键,选择【Run As】,进一步【Junit Test】。Junit出现绿条,并且控制台输出如下结果,则测试通过。

 

list.size():1
pd.id:helloworld-1
deploymentId:1
after del list count:0

 

 

管理流程实例

主要功能包括:

-发起新流程

-执行等待的流程

-查看流程实例

-终止流程实例

-删除流程实例

 

import java.util.List;

import org.jbpm.api.Configuration;
import org.jbpm.api.ExecutionService;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.ProcessInstance;

import junit.framework.TestCase;


public class ProcessInstanceTest extends TestCase {

	ProcessEngine processEngine;
	
	public ProcessInstanceTest() {
		processEngine = Configuration.getProcessEngine();
	}
	@Override
	protected void setUp() throws Exception {
		processEngine.getRepositoryService().createDeployment()
		.addResourceFromClasspath("helloworld.jpdl.xml").deploy();
	}
	
	/**
	 * 流程实例state节点向下执行
	 */
	public void testProcessInstance(){
		ExecutionService es= processEngine.getExecutionService();
		//流程实例
		ProcessInstance pi = es.startProcessInstanceByKey("helloworld");
		//state向下执行
		pi= es.signalExecutionById(pi.getId());
		System.out.println("pi.isEnded"+pi.isEnded());
	}
	
	/**
	 * 终止流程实例
	 */
	public void testProcessInstanceEnd(){
		ExecutionService es= processEngine.getExecutionService();		
		//流程实例
		ProcessInstance pi = es.startProcessInstanceByKey("helloworld");
		//终止流程实例
		es.endProcessInstance(pi.getId(), "结束流程");
	}
	
	/**
	 * 删除流程实例
	 */
	public void testProcessInstanceDel(){
		ExecutionService es= processEngine.getExecutionService();		
		//流程实例
		ProcessInstance pi = es.startProcessInstanceByKey("helloworld");
		//删除流程实例
		es.deleteProcessInstanceCascade(pi.getId());
	}
	
	/**
	 * 流程实例列表
	 */
	public void testProcessInstanceList(){
		ExecutionService es= processEngine.getExecutionService();		
		//流程实例
		ProcessInstance pi = null;
		for (int i = 0; i < 10; i++) {
			pi= es.startProcessInstanceByKey("helloworld");			
		}
		//查询流程实例列表
		List<ProcessInstance> list= es.createProcessInstanceQuery().list();
		//输出列表数到控制台
		System.out.println("list.size:"+list.size());
	}	
}

 

 

以下是测试用的工程,有需要的朋友可以下载运行看看结果!当然环境配置是必须的,关于环境配置请参考我的上一篇博客。
