【Activiti学习之八】Spring整合Activiti
时间:2019-10-10
本文章向大家介绍【Activiti学习之八】Spring整合Activiti，主要包括【Activiti学习之八】Spring整合Activiti使用实例、应用技巧、基本知识点总结和需要注意事项，具有一定的参考价值，需要的朋友可以参考一下。
环境
JDK 1.8
MySQL 5.6
Tomcat 7
idea
activiti 5.22
activiti-explorer是官方提供的一个演示项目，可以使用页面管理Activiti流程。activiti-explorer是以war包的形式存的。这里整合Spring+Activiti Modeler。
一、资源文件准备
1、下载activiti-5.22.0.rar
官网下载比较慢，可以从这里下载：https://pan.baidu.com/s/1XVTammPbIrbzU1MK7TBFOA
2、解压activiti-5.22.0.rar
进入wars目录，解压activiti-explorer.war demo
我们需要以下文件：
(1)diagram-viewer、editor-app、modeler.html
(2)stencilset.json（原版的title、description描述都是英文，可以改成中文：传送门）
二、搭建maven web工程
这里搭建传统应用：Spring + SpringMVC + Mybatis + Activiti
1、pom.xml

三、整合activiti-explorer
1、将diagram-viewer、editor-app、modeler.html拷贝到src/main/webapp下
2、将stencilset.json拷贝到/src/main/resources下
