业务可视化-让你的流程图"Run"起来(4.实际业务场景测试)
前言
首先，感谢大家对上一篇文章[业务可视化-让你的流程图"Run"起来(3.分支选择&跨语言分布式运行节点)]的支持。
下面我以实际业务场景为例，来介绍一下ladybugflow的使用方法。
酒店预定场景（传统写法）
对于下面的酒店预定流程
流程1：
流程2
[流程1]的传统写法1：
定义流程间共享变量;
开始处理();
查询客户信息处理();
查询酒店信息处理();
下单处理();
下单成功处理();假设每个流程用3秒钟，整个流程执行完需要3*5=15秒。
于是衍生出了写法2：
定义流程间共享变量;
开始处理();
启动 查询客户信息线程处理 A;
启动 查询酒店信息线程处理 B;
等待A,B结束;
下单处理();
下单成功处理();节省了时间，但各种多线程的实现方式使程序变得复杂，
而且上述写法都把流程图与业务逻辑进行了绑定，
也就是流程图中添加，删除节点后，相应的逻辑代码也要修改，测试范围往往是整个流程图的业务逻辑都要进行测试。
酒店预定场景（新写法）
针对上面的问题，我在设计ladybugflow的时候，把流程图和业务逻辑进行了分离，
每个业务逻辑对应一个方法，与流程图中的节点进行绑定。
这样修改流程图就不用修改业务逻辑了。
而且流程图可以通过工具拖拽方式生成，还可以在图上查看运行结果。
下面介绍一下ladybugflow中的开发过程
1. 导入依赖
Maven
<!-- https://mvnrepository.com/artifact/io.github.nobuglady/ladybugflow -->
<dependency>
<groupId>io.github.nobuglady</groupId>
<artifactId>ladybugflow</artifactId>
<version>0.0.6</version>
</dependency>Gradle
// https://mvnrepository.com/artifact/io.github.nobuglady/ladybugflow
implementation 'io.github.nobuglady:ladybugflow:0.0.6'2. 画流程图，并且生成Json文件
首先把这个文件下载到本地，用浏览器打开
https://github.com/nobuglady/ladybugflow/blob/main/html/network.html
然后点击页面上的[edit]按钮可以画流程图，
画完流程图后，点击[update json]按钮，可以生成流程图对应的json文件。
3. 写业务方法
流程图的每个节点对应下面的一个方法，用@Node注解来关联流程图。
可以用类变量进行参数传递和表示结果，比如下单成功后，设置类变量为"success"。
注：建议用节点ID进行关联，本文为了看起来方便，选择了中文的节点名称进行关联
Flow1.java(注意文件编码为UTF-8)
/**
*
* @author NoBugLady
*
*/
public class Flow1 extends FlowRunner {
private String result;
public String getResult() {
return result;
}
@Node(label = "start")
public void processStart() throws InterruptedException {
System.out.println("启动开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("启动结束");
}
@Node(label = "查询用户信息")
public void processSearchUser() throws InterruptedException {
System.out.println("查询用户信息开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("查询用户信息结束");
}
@Node(label = "查询酒店信息")
public void processSearchHotel() throws InterruptedException {
System.out.println("查询酒店信息开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("查询酒店信息结束");
}
@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")
public void processSuccess() throws InterruptedException {
System.out.println("下单成功开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("下单成功结束");
result = "success";
}
}4. 将流程图的Json文件放入工程
Flow1.json(注意文件编码为UTF-8)
{
"flowId": "your flow id",
"nodes": [
{
"id": "1",
"label": "start"
},
{
"id": "a1a38c2e-0e05-4c68-bd49-f12aea070876",
"label": "查询用户信息",
"readyCheck": 0
},
{
"id": "1a90a997-4390-470a-ae7c-626a725438d2",
"label": "查询酒店信息",

},
{
"id": "52289e99-363d-4453-8077-ca8bdc6d35bf",
"label": "下单",
"readyCheck": 0
},
{
"id": "16422cbb-ccb0-4fe2-952b-e3ad5c3acbb2",
"label": "下单成功",
"readyCheck": 0
}
],
"edges": [
{
"id": "1",
"from": "1",
"to": "2",
"arrows": "to"
},
{
"id": "b3ad7ab3-8fb6-4527-8cae-6845e03da3e4",
"from": "1",
"to": "a1a38c2e-0e05-4c68-bd49-f12aea070876",
"arrows": "to"
},
{
"id": "001375c7-19e7-436b-bbcd-68e36c8f23b7",
"from": "1",
"to": "1a90a997-4390-470a-ae7c-626a725438d2",
"arrows": "to"
},
{
"id": "dd830043-c7a7-4c71-b91c-10c007b7b19c",
"from": "1a90a997-4390-470a-ae7c-626a725438d2",
"to": "52289e99-363d-4453-8077-ca8bdc6d35bf",
"arrows": "to"
},
{
"id": "21c2c69d-0050-4eca-8283-5a2bcbdc6c37",
"from": "52289e99-363d-4453-8077-ca8bdc6d35bf",
"to": "16422cbb-ccb0-4fe2-952b-e3ad5c3acbb2",
"arrows": "to"
},
{
"id": "19f2f329-8163-4dc6-a353-800df79d18a6",
"from": "a1a38c2e-0e05-4c68-bd49-f12aea070876",
"to": "52289e99-363d-4453-8077-ca8bdc6d35bf",
"arrows": "to"
}
]
}项目结构如下图所示
Flow1.java和Flow1.json需要放到同一个包下。
5. 启动流程
App1.java(注意文件编码为UTF-8)
/**
*
* @author NoBugLady
*
*/
public class App1 {
public static void main(String[] args) {
Flow1 testFlow = new Flow1();
testFlow.startFlow(true);
System.out.println(testFlow.getResult());
// 不建议每次都调用shutdown,可以在整个App关闭的时候调用一次shutdown
FlowStarter.shutdown();
}
}6. 查看运行结果

带分支处理的酒店预定流程
ladybugflow提供了对流程图的分支处理功能。
可以根据节点的返回结果，执行不同的流程。
比如，上例中，增加【检查订单】节点，如下
检查订单成功，则走酒店预定流程，否则，走失败流程。
针对以上流程，我们对检查订单的两个边设置返回值，如下：

去除不必要的业务节点
实际使用过程中，并非每个业务节点都需要对应业务代码，
比如上例中【可以预定】和【不可预定】可以没有相应的业务逻辑，空跑一下转到后面的节点即可。
所以，我们可以在业务逻辑中去掉上述节点，如下，去掉了【可以预定】和【不可预定】对应的业务方法。
