本文介绍了在Activiti中如何设置和获取流程变量，包括整型、日期、字符串和自定义对象类型的变量。通过RuntimeService进行操作，变量可以在流程的整个生命周期内被访问，直到流程结束。示例代码详细展示了设置和获取变量的方法，对于理解和使用Activiti的流程变量管理具有指导意义。

/**

     */
    @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
    }

/**

@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());
}
