整合Flowable的项目报错如上图所示

解决方案

1.将连接数据库的url中添加（application.yml文件或其他）

nullCatalogMeansCurrent=true

2.查看数据库是否区分大小写

show variables like '%lower%';

lower_case_table_names 参数：

0： 表示区分大小写

1：表示不区分大小写

修改设置为不区分大小写

修改mysql的配置文件，找到[mysqld]部分，在后面追加如下内容：

[mysqld]
lower_case_table_names = 1

docker 运行mysql的情况：

将数据备份，删除原有的容器，run时挂载对应的宿主机文件夹，绑定参数--lower-case-table-names=1

docker run -v /etc/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /etc/mysql/data:/var/lib/mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:latest --lower-case-table-names=1
