Preface
First , Thank you for your comments on the last article [ Business visualization - Let your flowchart "Run" get up (3. Branch selection & Cross language distributed running nodes )] Support for .
Let me take the actual business scenario as an example , Let's introduce ladybugflow How to use .
Hotel reservation scenario （ The traditional way of writing ）
For the following hotel reservation process
technological process 1：
technological process 2
[ technological process 1] The traditional way of writing 1：
Define shared variables between processes ;
Start to deal with ();
Query customer information processing ();
Query hotel information processing ();
Order processing ();
The order was successfully processed ();
Suppose each process uses 3 Second , The whole process needs 3*5=15 second .
So the writing method is derived 2：
Define shared variables between processes ;
Start to deal with ();
start-up Query customer information thread processing A;
start-up Query hotel information thread processing B;
wait for A,B end ;
Order processing ();
The order was successfully processed ();
Save time , But the implementation of multithreading makes the program complex ,
And the above writing puts The flow chart is bound with the business logic ,
That is, add , After deleting a node , The corresponding logic code should also be modified , The test scope is often that the business logic of the whole flow chart should be tested .
Hotel reservation scenario （ neographism ）
Answer the above question , I'm designing ladybugflow When , hold The flow chart and business logic are separated ,
Each business logic corresponds to a method , Bind with the nodes in the flowchart .
In this way, there is no need to modify the business logic when modifying the flow chart .
And the flow chart can be generated by tool dragging , You can also view the running results on the graph .
So let's talk about that ladybugflow Development process in
1. Import dependence
Maven
<dependency>
<groupId>io.github.nobugladygroupId>
<artifactId>ladybugflowartifactId>
<version>0.0.6version>
dependency>
Gradle
// https://mvnrepository.com/artifact/io.github.nobuglady/ladybugflow
implementation 'io.github.nobuglady:ladybugflow:0.0.6'
2. Draw flow chart , And generate Json file
First, download this file locally , Open with a browser
https://github.com/nobuglady/ladybugflow/blob/main/html/network.html
Then click on the page [edit] Buttons can draw flow charts ,
After drawing the flow chart , Click on [update json] Button , You can generate the corresponding json file .
3. Write business methods
Each node of the flowchart corresponds to the following method , use @Node Annotations to associate flow charts .
You can use class variables to pass parameters and express results , For example, after placing an order successfully , Set the class variable to "success".
notes ： It is recommended to use nodes ID Association , This article is for convenience , Select the Chinese node name for Association
Flow1.java( Note that the file code is UTF-8)

The project structure is shown in the figure below
Flow1.java and Flow1.json It needs to be put under the same bag .
5. Start process

public class App1 {
public static void main(String[] args) {
Flow1 testFlow = new Flow1();
testFlow.startFlow(true);
System.out.println(testFlow.getResult());
// It is not recommended to call every time shutdown, Can be in the whole App Call once when closing shutdown
FlowStarter.shutdown();
}

Hotel reservation process with branch processing
ladybugflow It provides branch processing function for flow chart .
According to the return result of the node , Perform different processes .
such as , In the above example , increase 【 Check order 】 node , as follows
Check the order successfully , Then go through the hotel reservation process , otherwise , Follow the failure process .
For the above process , We set the return value on both sides of the check order , as follows ：

green ： Successful implementation , Red ： Execution failure , white ： unexecuted
Remove unnecessary business nodes
In actual use , Not every business node needs a corresponding business code ,
For example, in the above example 【 You can book 】 and 【 No reservations 】 There can be no corresponding business logic , Just jump to the next node .
therefore , We can remove the above nodes from the business logic , as follows , Removed 【 You can book 】 and 【 No reservations 】 Corresponding business method .
