JBPM （四） 浅析JBPM中的实例变量和任务变量

	@Override
	public void addProcessVariable() {
		
		//hashMap对象
		Map<String, Object> variable=new HashMap<String, Object>();
		//给map添加key和value值
		variable.put("userId", "001");
		variable.put("userName", "李龙生");
		//将变量添加到流程实例中
		ProcessInstance processInstance=executionService.startProcessInstanceByKey("test", variable);
		
	}

	public void modifyMyVariable()
	{
		//根据流程实例的ID修改，流程实例变量
		executionService.setVariable("test.20001", "userId", "002");
	}

	public void findMyVariable()
	{
		//根据实例ID，查询所有实例变量的名字
		Set<String> variableSet=executionService.getVariableNames("test.20001");
		
		Iterator iterable=variableSet.iterator();
		
		while (iterable.hasNext()) {
			System.out.println(iterable.next());
		}
		//根据实例ID和实例变量名字，查询所属实例变量的值
		Map<String, Object> map=executionService.getVariables("test.20001", variableSet);
		Iterator iterator=map.entrySet().iterator();
		
		while (iterator.hasNext()) {
			Map.Entry mEntry=(Map.Entry)iterator.next();
			this.print(mEntry.getKey().toString(),mEntry.getValue().toString());
			
		}
