流程属性

<process id="holiday2" isClosed="false" isExecutable="true" processType="None" name="第一个流程">

userTask属性设置

<userTask activiti:assignee="${assignee0}" activiti:exclusive="true" id="_3" name="填写请假单"/>
activiti:assignee="${assignee0}" 动态绑定assignee

//1.得到ProcessEngine对象
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        //2.得到RuntimeService对象
        RuntimeService runtimeService = processEngine.getRuntimeService();
       //3.设置assignee的取值   用户可以在界面上设置流程的执行人
        Map<String,Object> map = new HashMap<String,Object>();
        map.put("assignee0","zhangsan");
        map.put("assignee1","lishi");
        map.put("assignee2","wangwu");
        //4.启动流程实例，同时还要设置流程定义的assignee的值
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("holiday2", map);
        //5.输出
        System.out.println(processEngine.getName());
