前言

遇到问题,可以先从以下几个方面查找

流程运行中如果待办人为空或待办人不对需要修改流程变量

通过流程实例ID查看运行中的变量 SELECT * FROM act_ru_variable WHERE PROC_INST_ID_='6df4bec35f0311edb9432e92f39c67f4'; 通过流程实例ID查看历史流程变量 SELECT * FROM act_hi_varinst WHERE PROC_INST_ID_='6df4bec35f0311edb9432e92f39c67f4';

流程引擎后台启动卡住:liquibase - Waiting for changelog lock....

控制台提示如下：

2021-02-14 13:45:13.735 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:45:23.739 [main] INFO  liquibase - Waiting for changelog lock....

2021-02-14 13:46:13.767 [main] INFO  liquibase - Waiting for changelog lock....
2021-02-14 13:46:23.773 [main] INFO  liquibase - Waiting for changelog lock....

原因：表被意外锁住 解决方案：把 b'1' 改成 b'00000000' 即可 image.png

前端项目build的时候报内存溢出错误解决 - JavaScript heap out of memory

解决方案： build前执行export NODE_OPTIONS=--max_old_space_size=4096

# input your command here
npm config set registry https://registry.npm.taobao.org/

cd ./hopeflow-admin-ui/
echo "开始安装"
yarn install
echo  "开始构建"
export NODE_OPTIONS=--max_old_space_size=4096
yarn build
