设置流程变量

public void createInstance() {
		// TODO Auto-generated method stub
		super.startUp();
		Map<String, String> map = new HashMap<String, String>();
		map.put("id", "000001");
		map.put("name", "zuoshunjian");
		ProcessInstance processInstance = this.executionService
				.startProcessInstanceByKey("test", map);
		super.print("流程实例ID", processInstance.getId());
	}
获取流程变量

	/**
	 * 获取流程变量
	 */
	@Test
	public void getVariable() {
		super.startUp();
		String idString = this.executionService.getVariable("test.10001", "id")
				.toString();
		super.print("流程实例变量ID", idString);
	}
修改流程变量

	public void updateVariable() {
		super.startUp();
		this.executionService.setVariable("test.10001", "id", "00002");
		String idString = this.executionService.getVariable("test.10001", "id")
				.toString();
		System.out.println(idString);
