概 述

第一种方法：设置流程变量

/** 
　　　* 设置流程变量数据
     */
    @Test
    public void setVariableValues(){
        RuntimeService runtimeService=processEngine.getRuntimeService(); // 任务Service
        String executionId="90001";
        runtimeService.setVariable(executionId, "days", 2);
        runtimeService.setVariable(executionId, "date", new Date());
        runtimeService.setVariable(executionId, "reason", "发烧");
        Student student=new Student();
        student.setId(1);
        student.setName("张三");
        runtimeService.setVariable(executionId, "student", student); // 存序列化对象
    }

/**
* 获取流程变量数据
*/
@Test
public void getVariableValues(){
RuntimeService runtimeService=processEngine.getRuntimeService(); // 任务Service
String executionId=“102501”;
Integer days=(Integer) runtimeService.getVariable(executionId, “days”);
Date date=(Date) runtimeService.getVariable(executionId, “date”);
String reason=(String) runtimeService.getVariable(executionId, “reason”);
Student student=(Student) runtimeService.getVariable(executionId, “student”);
System.out.println(“请假天数：”+days);
System.out.println(“请假日期：”+date);
System.out.println(“请假原因：”+reason);
System.out.println(“请假对象：”+student.getId()+","+student.getName());
}

分析：

小结

：而RuntimeService绑定的是act_ru_execution表的executionId。任务ID随着任务节点的变化而变化，而executionId一般不会改变。

同样，用RuntimeService设置的值同样在接下来的流程都可以获取，知道流程结束
通过Activiti 流程部署方式 activi 动态部署，请大家指正~
