替换自己项目的parent和dependencies

application.yaml

spring:
  application:
    name: crazyFur-springboot-flowable
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/flowable?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true&nullCatalogMeansCurrent=true
    username: root
    password: root
# 工作流 Flowable 配置
flowable:
  database-schema-update: true # 设置为 false，可通过 https://github.com/flowable/flowable-sql 初始化
  async-executor-activate: true
server:
  port: 8888

记得把数据库改成自己的数据库配置哟

主动启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CrazyfurSpringbootFlowableApplication {

    public static void main(String[] args) {
        SpringApplication.run(CrazyfurSpringbootFlowableApplication.class, args);
    }

}

启动项目，检查flowable相关的表是否已经生成,没有生成需要自行百度检查哟-看到有表了就表示🆗了

安装flowable-ui

解压flowable-6.8.0.zip

将flowable-ui.war放到tomcat的webapps目录下

启动tomcat

访问http://localhost:8080/flowable-ui/idm/#/login登录

flowable.common.app.idm-admin.user=admin 默认用户名admin
flowable.common.app.idm-admin.password=test 默认密码test

登录成功后的页面

helloworld

使用flowable-ui画流程图
