外掛安裝
BPMN繪圖視覺化工具
Flowable BPMN visualizer
匯入依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--flowable工作流依賴--> <dependency> <groupId>org.flowable</groupId> <artifactId>flowable-spring-boot-starter</artifactId> <version>6.3.0</version> </dependency> <!--mysql依賴--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.45</version> </dependency>
新建資料庫
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: #關閉定時任務JOB async-executor-activate: false database-schema-update: true server: port: 8081
配置說明:
database-schema-update: true
資料庫更新策略,其取值有四個:
flase: 預設值。activiti在啟動時,會對比資料庫表中儲存的版本,如果沒有表或者版本不匹配,將丟擲異常。(生產環境常用)
true: activiti會對資料庫中所有表進行更新操作。如果表不存在,則自動建立。(開發時常用)
create_drop: 在activiti啟動時建立表,在關閉時刪除表(必須手動關閉引擎,才能刪除表)。(單元測試常用)
drop-create: 在activiti啟動時刪除原來的舊錶,然後在建立新表(不需要手動關閉引擎)。
定義流程檔案
這裡還是用一個開源的流程檔案
放在:resources/processes/ExpenseProcess.bpmn20.xml
