论坛：https://forum.camunda.org/

一、创建 spring boot 项目，添加项目依赖

注意：

01.camunda 是基于 activiti5.x 改造的新框架

02. camunda 与高版本 mysql 不兼容，需要使用 5.x 版本的 mysql

二、修改配置文件

application.properties 重命名： application.yml

#camunda 配置
camunda:
  bpm:
    admin-user:
      id: admin
      password: admin
      firstName: admin
    filter:
      create: All tasks
    job-execution:
      enabled: true
    metrics:
      enabled: false
      db-reporter-activate: false

#mysql 数据库配置
spring:
  application:
    name: wct-iot
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost/camunda02?serverTimezone=GMT%2B8&autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8&useSSL=false
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource

#服务端口
server:
  port: 8080
