业务可视化-让你的流程图“Run“起来(6.定时任务&Spring-Batch的集成)

前言

分享一下近期我对这个项目的一些改进。

在项目中，经常会有一些批处理的定时任务需要配置，目前的java项目一般采用Spring-Batch来作为批处理的平台。

但是Spring-Batch在对Job流程（并行，分支，条件分支，合并等）的支持略显复杂臃肿。

尤其是流程可视化这方面几乎不支持。

所以，最近对ladybugflow做了改进，在天然支持可视化流程的基础上，追加了对定时任务的支持。

本篇文章介绍ladybugflow定时任务的配置，和与SpringBatch相结合完成批处理的可视化操作的例子。

定时任务

对于流程的执行，前面文章介绍了流程的启动方法，如下：

Flow1 testFlow = new Flow1();
testFlow.startFlow(true);

这样只能完成流程的一次启动，如果需要定时启动流程，ladybugflow提供了在启动节点中设置cron表达式的方法来实现定时启动流程。

cron表达式

我们首先简单的了解一下cron表达式

Cron表达式是有六个空格分隔的时间和日期字段（域）组成的字符串。

┌───────────── second (0-59)

│ ┌───────────── minute (0 - 59)

│ │ ┌───────────── hour (0 - 23)

│ │ │ ┌───────────── day of the month (1 - 31)

│ │ │ │ ┌───────────── month (1 - 12) (or JAN-DEC)

│ │ │ │ │ ┌───────────── day of the week (0 - 7)

│ │ │ │ │ │          (0 or 7 is Sunday, or MON-SUN)

│ │ │ │ │ │

*  *  *  *  *  *

比如：

“0 0 * * * *” = 每天 00:00。

"*/10 * * * * *" = 每 10 秒。

“0 0 8-10 * * *” = 每天 8、9 和 10 个小时。

"0 0 6,19 * * *" = 每天早上 6:00 和晚上 7:00。

“0 0/30 8-10 * * *” = 每天 8:00、8:30、9:00、9:30、10:00 和 10:30。

"0 0 9-17 * * MON-FRI" = 工作日 9 到 5

“0 0 0 25 12 ?” = 圣诞节午夜

"0 0 0 L * *" = 每个月的午夜

"0 0 0 L-3 * *" = 每月第三天到最后一天午夜

"0 0 0 1W * *" = 每月第一个工作日午夜

"0 0 0 LW * *" = 每月最后一个工作日的午夜

"0 0 0 * * 5L" = 每月最后一个星期五的午夜

"0 0 0 * * THUL" = 每月最后一个星期四的午夜

"0 0 0 ? * 5#2" = 每月第二个星期五的午夜

"0 0 0 ? * MON#1" = 每月第一个星期一的午夜

在ladybugflow中配置cron表达式

在流程编辑器中，将流程的首节点的启动类型设置成Timer，然后输入cron表达式，如下图所示

点击更新，更新json，

将json字符串拷贝到工程里，

启动工程，如下：

定时任务的实现方式

ladybugflow采用spring的scheduling来实现对cron表达式的解析，

流程启动后，如果首节点类型是Timer，则会根据cron表达式来向ThreadPoolTaskScheduler中注册一个定时任务。

taskScheduler.schedule(new Runnable() {
	@Override
	public void run() {

		try {
			FlowRunner flowRunnerNew = flowRunner.getClass().newInstance();

			String flowPath = flowRunnerNew.getClass().getName();

			if (StringUtil.isNotEmpty(jsonFileName)) {
				flowPath = jsonFileName.replace(".json", "");
			}

			FlowEntity flow = createHistory(flowPath);
			String flowId = flow.flowEntity.getFlowId();
			String historyId = flow.flowEntity.getHistoryId();

			FlowContainer.flowRunnerMap.put(flowId + "," + historyId, flowRunnerNew);
			
			HistoryNodeEntity firstNode = FlowContainer.selectNodeByKey(flowId, nodeId, historyId);
			firstNode.setNodeStatus(NodeStatus.READY);
			startNode(flowId, historyId, nodeId);

		} catch (InstantiationException e) {
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			e.printStackTrace();
		}

	}
}, new CronTrigger(cron));

Spring-Batch与ladybugflow的集成

1.新建一个Spring-Batch工程，并且导入ladybugflow。

build.gradle

plugins {
	id 'org.springframework.boot' version '2.7.2'
	id 'io.spring.dependency-management' version '1.0.12.RELEASE'
	id 'java'
}

group = 'nobuglady'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.springframework.boot:spring-boot-starter-batch'
	implementation 'io.github.nobuglady:ladybugflow:0.0.8'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

tasks.named('test') {
	useJUnitPlatform()
}

将生成的Json文件和对应的Flow.java文件放在同一个目录下：

Flow1.java

		System.out.println("启动开始 （模拟业务等待3秒）");
		Thread.sleep(3000);

	}

	@Node(label = "查询用户信息")
	public void processSearchUser() throws InterruptedException {

	}

	@Node(label = "下单")
	public void processOrder() throws InterruptedException {
		System.out.println("下单开始 （模拟业务等待3秒）");
		Thread.sleep(3000);
		System.out.println("下单结束");
	}

	@Node(label = "下单成功")
