Dynamically create Flowable workflow in Spring Boot

Dynamically creating a Flowable workflow in Spring Boot can be achieved through the following steps:

1. Create Flowable configuration: First, you need to configure Flowable in your Spring Boot application. You can configure Flowable using Spring Boot configuration files or annotations.

2. Create a workflow definition: Next, you need to create a workflow definition. You can use Flowable's API to create workflow definitions.

3. Dynamically create workflow instances: Finally, you can use Spring Boot's API to dynamically create workflow instances. You can use Spring Boot annotations or configuration files to define how workflow instances are created.

For example, here is an example of dynamically creating a workflow using Spring Boot and Flowable:

 

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    
    @Autowired
    private FlowableProcessEngine processEngine;
    
    @PostConstruct
    public void init() {
        // 创建工作流定义
        BpmnModel bpmnModel = new BpmnModel();
        bpmnModel.addFlowElement(new FlowableUserTask());
        
        // 动态创建工作流实例
        ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey("dynamic-workflow", bpmnModel);
    }
}

 

In this example, we use Spring Boot’s @SpringBootApplication annotation to start the application. In the @PostConstruct method, we dynamically create a workflow instance using the FlowableProcessEngine object.
