activiti工作流使用一般步骤

activiti工作流使用的一般步骤

一、在eclipse或Myeclipse中安装activiti插件；

二、通过activiti连接数据库，有以下两种连接数据库的形式：

1.通过java代码链接数据库：

public void createTableByOracle(){

		ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();

		configuration.setJdbcUrl("jdbc:oracle:thin:@192.168.1.150:1521:orcl");

		configuration.setJdbcDriver("oracle.jdbc.OracleDriver");

		configuration.setJdbcUsername("scott");

		configuration.setJdbcPassword("oracle");

		configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);

		ProcessEngine processEngine = configuration.buildProcessEngine();

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

		System.out.println(processEngine);

	}

2.通过配置文件配置链接数据库

（1）配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

  xmlns:jee="http://www.springframework.org/schema/jee" xmlns:aop="http://www.springframework.org/schema/aop"

  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd

       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

       http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd

       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

	<bean id="dataSource"

		class="org.springframework.jdbc.datasource.SimpleDriverDataSource">

		<property name="driverClass" value="com.mysql.jdbc.Driver" />

		<property name="url" value="jdbc:mysql://192.168.1.150:3306/officemanage?characterEncoding=utf8" />

		<property name="username" value="root" />

		<property name="password" value="123456" />

	</bean>

	 <bean id="transactionManager"

		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

		<property name="dataSource" ref="dataSource" />

	</bean>

	<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">

		<property name="dataSource" ref="dataSource" />

		<property name="transactionManager" ref="transactionManager" />

		<property name="databaseSchemaUpdate" value="true" />

	</bean>

</beans>

（2）java代码读取配置文件链接数据库：

public void createTableByXML(){

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

	}

三、创建工作流的bpmn类型的文件：

四、部署bpmn和png类型的工作流文件资源：（注意：一个工作流程部署一次即可，以后只需要启动一条流程即可）

public void deployTest(){

		System.out.println("开始部署一个审批流程");

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		Deployment deployment = processEngine.getRepositoryService().createDeployment().name("路费报销审批流程").addClasspathResource("choiceProcess.bpmn").addClasspathResource("choiceProcess.png").deploy();

		System.out.println("部署流程完毕");

	}

五、启动一条流程：

public void StartProcess(){

		System.out.println("开始启动一个审批流程");

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey("luFeiBaoXiaoShenPi");

		System.out.println(processInstance.getId()+"--------"+processInstance.getActivityId());

		System.out.println("启动流程完毕");

	}

六、查看某个人要完成的任务列表：

public void queryProcess(){

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		String assignee0 = "lsy";

		List<Task> zhangSanList = processEngine.getTaskService().createTaskQuery().taskAssignee(assignee0).orderByTaskCreateTime().asc().list();

		System.out.println("****************"+assignee0+"个人任务列表***********************");

		for (Task task : zhangSanList) {

			System.out.println("id:"+task.getId()+",名称："+task.getName()+",创建时间"+task.getCreateTime()+",人物："+task.getAssignee());

		}

	}

七、某个人完成自己的某个任务：

1.不带变量：

public void completeTask(){

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		processEngine.getTaskService().complete("235009");

		System.out.println("完成任务");

	}

2.带变量：

public void completeTaskByVariables(){

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		Map<String, Object> variables = new HashMap<String,Object>();

		variables.put("money", 501);

		processEngine.getTaskService().complete("265004",variables);

		System.out.println("完成任务");

	}

八、某个人查看自己已完成的任务列表：

public void queryHistoryTask(){

		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

		List<HistoricTaskInstance> historicList = processEngine.getHistoryService().createHistoricTaskInstanceQuery().taskAssignee("lsy").list();

		for (HistoricTaskInstance historicTaskInstance : historicList) {

			System.out.println(historicTaskInstance.getId()+":"+historicTaskInstance.getProcessDefinitionId()+":"+historicTaskInstance.getAssignee()+":"+historicTaskInstance.getExecutionId()+":"+historicTaskInstance.getStartTime()+":"+historicTaskInstance.getEndTime()+":"+historicTaskInstance.getDurationInMillis());

		}

	}
