  </dependencies>


2、application.properties

     ###第一次项目启动,库flowable-spring-boot表自动生成


  server.port=2065
  # 数据源名称
  spring.datasource.name=test
  # 数据库连接地址
  spring.datasource.url=jdbc:mysql://localhost:3306/flowable-spring-boot?characterEncoding=UTF-8&serverTimezone=UTC
  # 数据库用户名&密码:
  spring.datasource.username=root
  spring.datasource.password=root
  # 数据库驱动:
  spring.datasource.driver-class-name=com.mysql.jdbc.Driver

  #关闭定时任务
  flowable.async-executor-activate=false

  logging.level.root=info
  logging.com.sc.flowable2065=debug
  logging.file.name=flowable-test.log

 

 


3、工作流文件,使用工具【 Flowable UI applications

二、整体流程开始

1、创建流程

 流程id 7505

2、查询待办列表

 

 

3、同意      taskid:7511

  

 

4、生成流程图
