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());
		}
	}
