2017.2.20 activiti实战--第二章--搭建Activiti开发环境及简单示例(一)搭建开发环境
学习资料:《Activiti实战》
第一章 认识Activiti
2.1 下载Activiti
官网:http://activiti.org/download.html
进入下载页后,可以看到最新版本的压缩包、快速入门、用户手册、javadoc等。我下载的时候,最新版本是activiti-5.22.0.zip。
目录结构:
database:
包含了activiti表的创建、删除及版本升级三种类型的脚本。
创建和删除脚本的命名规则:activiti.[oracle|postgres|db2|mssql|mysql|h2|hsql].[create|drop].[identity|engine|history].sql
版本升级脚本的命名规则:activiti.oracle.upgradestep.[5x].to.[5(x+1)].history
docs:
包含了javadocs、用户手册和xsd。用户手册包含了环境配置,十分钟快速入门,各模块使用教程。xsd中包含与流程定义相关的scheme。
libs:略。
war:略。
2.2 环境配置
jdk、maven、intellij。
2.3 配置文件介绍
2.3.1 activiti.cfg.xml
(1)processEngineConfiguration
activiti可以单独使用,也可以与spring集成,所以配置文件有所区别。
单独模式:
与spring集成:
(2)database
activiti支持的数据库类型:
不论是单独模式,还是与spring集成,database都可以有如下配置方式。
jdbc方式(spring集成时也类似,不再重复):
dataSource方式(spring集成时也类似,不再重复):
2.3.2 pom.xml
如果不与spring集成,只需要activiti-engine。
如果需要与spring集成,需要加上activiti-spring。其中spring的配置此处略。
如果需要使用activiti的modeler,需要加上activiti-modeler。
