QuickMan 手记 - Activiti 环境搭建

基础环境

环境搭建是一个无聊乏味的过程 ,这里使用 scoop 直接搭建完成 ,不知道 scoop 可以访问我的博客 .

测试环境搭建，当然 ,如果你的博客已经有了下面这些环境 ,不需要安装直接体验 .

scoop install java/oraclejdk8
scoop install idea-ultimate
scoop install eclipse-jee
scoop install extras/mysql56
scoop install maven

Mysql 这里启动就是最基本的命令 , mysqld .可能会提示你缺少一些 dll 文件 ,百度搜索解决即可 ,然后通过 mysql 连接 .

Maven 中央仓

下载好 Maven 复制一份 conf/setting.xml 到用户文件 ~/.m2 下 ,在 mirror 添加阿里中央仓 ,如下所示 .

    <!-- 阿里中央仓 --><mirror><id>ali</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror>

eclipse - 设计 BPM 工具

添加软件源 https://www.activiti.org/designer/update/

创建 Activiti 项目并在 main/resource 下创建流程图 .

设计一个流程图 ,这个有点技术的都应该知道 ,灰常简单 .我设计的流程图 ,截图如下 :

这个工具 idea

又爱又恨的 idea ,其实熟悉操作了就好了 .文件目录结构如下 :

----Leaveman|----apps|----activiti 学习 act 中 ,希望做出一个灵活调整的请销假系统 ;|----swagger 未完成

activiti.pom 配置文件如下 :

```java

<?xml version="1.0" encoding="UTF-8"?>
