本文介绍warm-flow工作流，监听器和参数传递使用，是非常简单的

1、实现一下接口

start：开始监听器，当前任务开始前执行

finish：结束监听器，当前任务完成后执行

assignment：分派办理人监听器，分派后执行

public interface Listener extends Serializable {

    String LISTENER_START = "start";
    String LISTENER_END = "finish";
    String LISTENER_ASSIGNMENT = "assignment";

    void notify(ListenerVariable variable);
}
public class FinishListener implements Listener {
    private static final Logger log = LoggerFactory.getLogger(StartListener.class);

    @Override
    public void notify(ListenerVariable variable) {
        log.info("完成监听器:{}", variable);
        Instance instance = variable.getInstance();
        Map<String, Object> testLeaveMap = variable.getVariable();
        log.info("完成监听器结束;{}", "任务完成");
    }
}

2、页面配置监听器，传递后台通过逗号分割不同监听器

3、参数传递

// 流程变量
Map<String, Object> variable = new HashMap<>();
variable.put("testLeave", testLeave);
flowParams.variable(variable);
Instance instance = insService.skip(taskId, flowParams);
