activiti 个人任务指定办理人三种方式（十）

1.  流程图

2. 执行人指定类、实现类

	// 指定任务的办理人
	public void notify(DelegateTask delegateTask) {
		delegateTask.setAssignee("张一");
	}

/**
 * 指定办理人三种方式<br>
 * 1.直接在活动中制定assignee<br>
 * 2.在asssgine中设置变量${person}，在启动时，设置人员<code>startProcessInstanceByKey(
<span style="white-space:pre">				</span>processInstanceKey, assignee)</code>
 * 3.使用类，动态制定代理人<br>
 * 另外：可以将任务分配给另外一个人
