工作流activiti5 使用流程变量

1、activiti配置文件activiti.cfg.xml

activiti.cfg.xml文件放在项目resources目录下，resources目录是activiti查找配置文件的默认目录

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
                          http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        <property name="databaseSchemaUpdate" value="true" />
        <property name="databaseType" value="mysql"/>
        <property name="dataSource" ref="dataSource"/>
        <property name="asyncExecutorActivate" value="false" />
        <property name="mailServerHost" value="mail.my-corp.com" />
        <property name="mailServerPort" value="5025" />
    </bean>
    
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/bpmn?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF8" />
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="username" value="root" />
        <property name="password" value="root" />
        <property name="defaultAutoCommit" value="false"/>
    </bean>
</beans>

2、流程图

<userTask activiti:assignee="#{userId}" activiti:exclusive="true" completionQuantity="1" id="_3" implementation="##unspecified" isForCompensation="false" name="approval task" startQuantity="1">
</userTask>
<userTask activiti:assignee="#{checkId}" activiti:exclusive="true" completionQuantity="1" id="_4" implementation="##unspecified" isForCompensation="false" name="check outcome" startQuantity="1">
</userTask>
使用#{userId}和#{checkId}设置流程变量

3、部署流程并启动流程实例

@Test
public void firstBpmn(){
   ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
   //部署流程
   RepositoryService repositoryService = processEngine.getRepositoryService();
   repositoryService.createDeployment()
         .addClasspathResource("third.bpmn")
         .deploy();
   //启动流程实例并设置流程变量
   Map<String,Object> variables = new HashMap<String,Object>();
   variables.put("userId","张三峰");
   variables.put("checkId","英语");
   ProcessInstance processInstance = processEngine.getRuntimeService()
         .startProcessInstanceByKey("PROCESS_2",variables);
   System.out.println("id:"+processInstance.getId());

}

4、查看个人任务

   @Test
   public void task(){
//    ProcessEngine processEngine = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml")
//          .buildProcessEngine();
      ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
      List<Task> zhangsan = processEngine.getTaskService().createTaskQuery().taskAssignee("张三峰").list();
      for (Task task:zhangsan){
         System.out.println(task.getId()+" ---- "+task.getName());
      }
   }
