配置文件

server: port: 8080 spring: #Activiti property configuration activiti: database-schema-update: true history-level: full db-history-used: true datasource: driver-class-name: com.p6spy.engine.spy.P6SpyDriver url: jdbc:p6spy:mysql://localhost:3306/activiti?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true username: root password: root type: com.alibaba.druid.pool.DruidDataSource 

安装actibpm插件

把编码设置成UTF8 

-Dfile.encoding=UTF-8

构建流程文件

 复制一份刚刚构建的流程文件，并将后缀名改为bpmn20.xml，打开后将报错的xmlns加上文件顶部的xmln约束

生成png文件，保存下来放到一起

如果启动报错找不到act_ge_property表的话就在数据库连接加上

&nullCatalogMeansCurrent=true

例如

jdbc:mysql://localhost:3306/activiti?characterEncoding=UTF-8&nullCatalogMeansCurrent=true&serverTimezone=GMT&useSSL=fals
