concept

Workflow products use activiti a lot. They come with a set of UI, which can be used directly to design processes. Here is a brief summary of its steps:

1 design model

2 publish as process. A model can publish multiple versions of process

3. Establish a process instance and instance task. A process can establish multiple parallel instances

4 approve an instance task

5 you can view the real-time process instance status

Add reference

   annotationProcessor  'org.projectlombok:lombok:1.18.2' //You need to reference lombok like this after gradle 5.0
    compileOnly 'org.projectlombok:lombok:1.18.2'
    testAnnotationProcessor 'org.projectlombok:lombok:1.18.2'
    testCompileOnly 'org.projectlombok:lombok:1.18.2'

Add startup file

import org.activiti.spring.boot.SecurityAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class, org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class,})
public class AvtivitiApplication {
    public static void main(String[] args) {
        SpringApplication.run(AvtivitiApplication.class, args);
    }

}
