一、开发环境调试

1.安装sdkman使用于管理java环境

curl -s “https://get.sdkman.io” | bash

source “$HOME/.sdkman/bin/sdkman-init.sh”

sdk version

2.安装jdk环境

sdk install java 8u161-oracle

java -version

echo $JAVA_HOME

3.下载tomcat

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.50/bin/apache-tomcat-8.0.50.zip

tar -zxvf apache-tomcat-8.0.50.zip

./apache-tomcat-8.0.50/bin/startup.sh

4.部署activiti

wget https://github.com/Activiti/Activiti/releases/download/activiti-6.0.0/activiti-6.0.0.zip

tar -zxvf activiti-6.0.0.zip

cp activiti-6.0.0/wars/activiti-admin.war apache-tomcat-8.0.50/webapps

cd apache-tomcat-8.0.50/bin

./startup.sh

5.这样就启动tomcat并且部署了activiti

查看网址：http://localhost:8080/activiti-app

账号admin 密码test

二、Activiti6.0快速体验

1.流程参加者

2.流程设计

3.http://localhost:8080/activiti-app打开网址登陆进去

点击identity manager创立使用户

4.kickstart APP创立一个流程

点击Create Process。输入流程信息

5.创立流程并且绑定使用户。保存并关闭编辑器。

6.创立一个app，并且管理流程

点击Apps后，新添加板块。

保存并且发布

7.进入管理员界面

http://localhost:8080/activiti-admin/#/login admin admin

点击Configuration

点击edit Activiti Rest endpoint

三、源码下载

进入github activiti主页，点击fork，到自己的github中。

git clone git@github.com:自己的账号/Activiti.git

cd activiti

git checkout -b activit-study activiti-6.0.0

mvn clean test-compile

四、入门小demo

五、打包

mvn package

cd target

java jar xx.jar
