activiti-explorer（activiti 5.22） 替换为mysql数据库

1、准备容器，比如tomcat
2、下载activiti：​​​https://github.com/Activiti/Activiti/releases​​​
3、导入数据库
4、将activiti-5.22.0中的activiti-explorer.war 放到 tomcat下webapps目录下运行tomcat解压war文件
5、修改activiti-explorer项目activiti-explorer\WEB-INF\classes下的db.properties文件

db=activiti
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

注意：db=activiti//填写的是数据库名字
6、修改activiti-explorer项目activiti-explorer\WEB-INF\classes下的activiti-coustom-context.xml文件，去掉注释，修改数据连接信息。
