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
