工作流是OA系统不可或缺的一部分,今天介绍一款新的工作流引擎flowable。flowable 是著名 Java 工作流引擎 Activiti 的原作者从 Activiti 分支创建的新工作流引擎。flowable 是一个业务流程管理(BPM)和工作流系统,适用于开发人员和系统管理员。其核心是超快速,稳定的BPMN2流程引;易于与 Spring集成使用。
1、Flowable 设计器Flowable Designer安装
下载地址:
https://blog.flowable.org/2016/11/01/flowable-eclipse-designer-5-22-0-release/
在线安装地址:

离线安装包地址:
http://www.flowable.org/designer/archived/flowable-designer-5.22.0.zip
2、 新建项目sc-flowable,对应的pom.xml文件如下
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.flowable</groupId> <artifactId>sc-flowable</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>sc-flowable</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.4.RELEASE</version> </parent> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- HikariCP 连接池依赖 --> <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> </dependency> <dependency> <groupId>org.flowable</groupId> <artifactId>flowable-spring-boot-starter-basic</artifactId> <version>6.4.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency> </dependencies> </project>
3、新建配置文件application.yml
spring: datasource: driver-class-name : com.mysql.jdbc.Driver url: jdbc:mysql://127.0.0.1:3306/flowable?characterEncoding=UTF-8 username: root password: root logging: level: ROOT: info flowable: #关闭定时任务JOB async-executor-activate: false #将databaseSchemaUpdate设置为true。当Flowable发现库与数据库表结构不一致时,会自动将数据库表结构升级至新版本。 database-schema-update: true
配置文件中主要配置数据库的地址、用户名及密码
4、新建springboot启动类
package com.flowable; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class FlowableApplication { public static void main(String[] args) { SpringApplication.run(FlowableApplication.class, args); } }
5、验证是否集成flowable成功
运行后FlowableApplication.java,期间没有任何异常信息;查看数据库,已经自动生成了flowable相关的表结构
