     public static void main(String[] args) {
    
     //1：定义ProcessEngine对象,自己封装的工具类也可以ProcessEngines.getDefaultProcessEngine();
    
     ProcessEngine processEngine= ReturnProcessEngineUtil.getProcessEngine();
    
     //2：获取runtimeService对象
    
     RuntimeService runtimeService=processEngine.getRuntimeService();
    
     //3：创建流程实例,流程定义的key需要知道
