在这里插入图片描述

插件安装

BPMN绘图可视化工具

Flowable BPMN visualizer

导入依赖


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--flowable工作流依赖-->
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>6.3.0</version>
        </dependency>
        <!--mysql依赖-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.45</version>
        </dependency>

新建数据库

database

javapub-flowable2

修改配置

spring:
  datasource:
    url: jdbc:mysql://bj-cdb-mw08tjgs.sql.tencentcdb.com:60042/javapub-flowable2?characterEncoding=UTF-8
    username: root
    password: password
    driver-class-name: com.mysql.jdbc.Driver
flowable:
  #关闭定时任务JOB
  async-executor-activate: false
  database-schema-update: true
server:
  port: 8081

配置说明:

database-schema-update: true

数据库更新策略,其取值有四个:

flase:       默认值。activiti在启动时,会对比数据库表中保存的版本,如果没有表或者版本不匹配,将抛出异常。(生产环境常用)
true:        activiti会对数据库中所有表进行更新操作。如果表不存在,则自动创建。(开发时常用)
create_drop: 在activiti启动时创建表,在关闭时删除表(必须手动关闭引擎,才能删除表)。(单元测试常用)
drop-create: 在activiti启动时删除原来的旧表,然后在创建新表(不需要手动关闭引擎)。

定义流程文件

这里还是用一个开源的流程文件

放在:resources/processes/ExpenseProcess.bpmn20.xml
