springboot~工作流activiti的搭建

概念

工作流产品使用activiti的算是比较多了，自带了一套UI界面，可以直接使用，用来设计流程，下面简单总结一下它的步骤：

1 设计模型

2 发布为流程，一个模型可以发布多个版本的流程

3 建立一个流程的实例和实例任务，一个流程可以建立多个并行的实例

4 对某个实例任务进行审批

5 可以查看实时的流程实例状态

部署在项目里

添加引用

annotationProcessor  'org.projectlombok:lombok:1.18.2' //gradle5.0之后需要这样引用lombok
 compileOnly 'org.projectlombok:lombok:1.18.2'
 testAnnotationProcessor 'org.projectlombok:lombok:1.18.2'
 testCompileOnly 'org.projectlombok:lombok:1.18.2'

添加启动文件

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);
    }
 
}

添加yml配置
