activiti设置变量（基本类型的和javaBean类型的）及历史查询（流程实例和历史活动）

 

1、设置并获取基本类型的变量  

package cn.et.db;

import java.util.Date;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.runtime.ProcessInstance;
import org.junit.Test;

public class Variable {
	ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
	/**
	 * 部署流程定义
	 */
	@Test
	public void deploymentProcessDefinition(){
		//流程定义和部署对象相关的service
		RepositoryService repositoryService = processEngine.getRepositoryService();
		//创建一个部署对象
		DeploymentBuilder createDeployment = repositoryService.createDeployment();
		createDeployment.name("hello activiti");
		//从classpath下加载资源，一次只能加载一个文件
		DeploymentBuilder addClasspathResource = createDeployment.addClasspathResource("diagrams/variable.bpmn").addClasspathResource("diagrams/variable.png");
		//完成部署
		Deployment deploy = addClasspathResource.deploy();
		System.out.println("部署id"+deploy.getId());
		System.out.println("部署名称"+deploy.getName());
	}
	
	/**
	 * 启动流程实例
	 */
	@Test
	public void startProcessInstance(){
		RuntimeService runtimeService = processEngine.getRuntimeService();
		ProcessInstance startProcessInstanceByKey = runtimeService.startProcessInstanceByKey("variable");
		System.out.println("流程实例id"+startProcessInstanceByKey.getId());
		System.out.println("流程定义id"+startProcessInstanceByKey.getProcessDefinitionId());
	}
	
	/**
	 * 设置变量
	 */
	@Test
	public void setVariable(){
		//设置任务流程的变量
		TaskService taskService = processEngine.getTaskService();
		taskService.setVariable("27504", "请假天数", 1);
		taskService.setVariable("27504","请假理由","病假");
		taskService.setVariable("27504","请假时间",new Date());
		System.out.println("ok");
	}
	
	
	/**
	 * 获取变量
	 */
	@Test
	public void getVariable(){
		TaskService taskService = processEngine.getTaskService();
		Object variable = taskService.getVariable("27504", "请假天数");
		Object variable2 = taskService.getVariable("27504", "请假理由");
		Object variable3 = taskService.getVariable("27504", "请假时间");
		System.out.println(variable+"   "+variable2+"   "+variable3);
	}
}

2、设置并获取javaBean类型

     javaBean（javaBean必须序列化 ）

package cn.et.db;

import java.io.Serializable;

public class Person implements Serializable{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private Integer id;
	private String name;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
}

 

package cn.et.db;

import java.util.Date;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.runtime.ProcessInstance;
import org.junit.Test;

public class Variable {
	ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
	/**
	 * 部署流程定义
	 */
	@Test
	public void deploymentProcessDefinition(){
		//流程定义和部署对象相关的service
		RepositoryService repositoryService = processEngine.getRepositoryService();
		//创建一个部署对象
		DeploymentBuilder createDeployment = repositoryService.createDeployment();
		createDeployment.name("hello activiti");
		//从classpath下加载资源，一次只能加载一个文件
		DeploymentBuilder addClasspathResource = createDeployment.addClasspathResource("diagrams/variable.bpmn").addClasspathResource("diagrams/variable.png");
		//完成部署
		Deployment deploy = addClasspathResource.deploy();
		System.out.println("部署id"+deploy.getId());
		System.out.println("部署名称"+deploy.getName());
	}
	
	/**
	 * 启动流程实例
	 */
	@Test
	public void startProcessInstance(){
		RuntimeService runtimeService = processEngine.getRuntimeService();
		ProcessInstance startProcessInstanceByKey = runtimeService.startProcessInstanceByKey("variable");
		System.out.println("流程实例id"+startProcessInstanceByKey.getId());
		System.out.println("流程定义id"+startProcessInstanceByKey.getProcessDefinitionId());
	}
	
	
	/**
	 * 使用javabean设置变量
	 */
	@Test
	public void setJavaBeanVariable(){
		TaskService taskService = processEngine.getTaskService();
		Person p=new Person();
		p.setId(1);
		p.setName("王小二");
		taskService.setVariable("40004", "人员信息", p);
		System.out.println("ok");
	}
	
	/**
	 * 获取javaBean
	 */
	@Test
	public void getJavaBeanVariable(){
		TaskService taskService = processEngine.getTaskService();
		Person variable = (Person)taskService.getVariable("40004", "人员信息");
		System.out.println(variable.getId()+"========="+variable.getName());
	}
}

SELECT *  FROM `act_ru_variable`  #正在执行的流程变量

SELECT * FROM `act_hi_varinst` #历史的流程变量

 

3、历史查询（流程实例和历史活动）

package cn.et.db;

import java.util.List;

import org.activiti.engine.HistoryService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.history.HistoricActivityInstance;
import org.activiti.engine.history.HistoricActivityInstanceQuery;
import org.activiti.engine.history.HistoricProcessInstance;
import org.activiti.engine.history.HistoricProcessInstanceQuery;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.runtime.ProcessInstanceQuery;
import org.junit.Test;

public class Isend {
	ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
	
	
	/**
	 * 查询历史流程实例
	 */
	@Test
	public void historyProcessInstance(){
		//与历史数据相关的service
		HistoryService historyService = processEngine.getHistoryService();
		//创建历史流程实例查询
		HistoricProcessInstanceQuery createHistoricProcessInstanceQuery = historyService.createHistoricProcessInstanceQuery();
		//使用流程实例id查询
		HistoricProcessInstanceQuery processInstanceId = createHistoricProcessInstanceQuery.processInstanceId("57501");
	
		/*HistoricProcessInstanceQuery orderByProcessInstanceStartTime = processInstanceId.orderByProcessInstanceStartTime().asc();
		HistoricProcessInstance singleResult = orderByProcessInstanceStartTime.singleResult();*/
		HistoricProcessInstance singleResult = processInstanceId.singleResult();
		System.out.println(singleResult.getId()+" "+singleResult.getStartTime()+"   "+singleResult.getEndTime());
	}
	
	/**
	 * 查询历史活动
	 */
	@Test
	public void historyActiviti(){
		//与历史数据相关的service
				HistoryService historyService = processEngine.getHistoryService();
				//创建历史活动实例查询
				HistoricActivityInstanceQuery createHistoricActivityInstanceQuery = historyService.createHistoricActivityInstanceQuery();
				//使用流程实例id查询
				HistoricActivityInstanceQuery processInstanceId = createHistoricActivityInstanceQuery.processInstanceId("57501");
				HistoricActivityInstanceQuery asc = processInstanceId.orderByHistoricActivityInstanceEndTime().asc();
				List list = asc.list();
				for(HistoricActivityInstance h:list){
					System.out.println(h.getId()+"====>"+h.getStartTime()+"=====>"+h.getEndTime());
					System.out.println("===================================");
				}
	}
	
}
