工做流是OA系統不可或缺的一部分，今天介紹一款新的工做流引擎flowable。flowable 是著名 Java 工做流引擎 Activiti 的原做者從 Activiti 分支建立的新工做流引擎。flowable 是一個業務流程管理(BPM)和工做流系統，適用於開發人員和系統管理員。其核心是超快速，穩定的BPMN2流程引；易於與 Spring集成使用。mysql

一、Flowable 設計器Flowable Designer安裝

二、新建項目sc-flowable，對應的pom.xml文件以下數據庫

<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 鏈接池依賴 -->
        <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>

三、新建配置文件application.ymlapache

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:
    #關閉定時任務JOB
    async-executor-activate: false
    #將databaseSchemaUpdate設置爲true。當Flowable發現庫與數據庫表結構不一致時，會自動將數據庫表結構升級至新版本。
    database-schema-update: true

配置文件中主要配置數據庫的地址、用戶名及密碼springboot

四、新建springboot啓動類app

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);
    }

}

五、驗證是否集成flowable成功
運行後FlowableApplication.java，期間沒有任何異常信息；查看數據庫，已經自動生成了flowable相關的表結構
