我在部署时，使用的是ruoyi-vue的3.8版本，后端数据库是sqlserver2012。从mysql改成sqlserver,改动项还是很多的。
sqlserver2012，mybatis的mapper中的list对应的sql语句需要增加order by(如果页面有分页逻辑)，否则报类似的错误：OFFSET ? ROWS FETCH NEXT ? ROWS ONLY
初步参考文章
ruoyi（若依）系统使用SqlServer数据库改动部分
这个篇文章讲解了一部分，有些地方没写的详细，我又根据自己部署实践，下边会补充完善一些。
maven配置修改

application-XXX.yml配置修改

数据库初始化脚本
数据库表的主键字段要设置成自增长的 IDENTITY(1, 1)
数据库初始化脚本

代码生成模块修改
生成消息初始化配置
路径：\ruoyi-generator\src\main\resources\generator.yml
gen:
# 作者
author: wade
# 默认生成包路径 system 需改成自己的模块名称 如 system monitor tool
packageName: com.ruoyi.customer
# 自动去除表前缀，默认是false
autoRemovePre: false
# 表前缀（生成类名不会包含表前缀，多个用逗号分隔）
tablePrefix: lx_
生成的sql文件
路径：\ruoyi-generator\src\main\resources\vm\sql\sql.vm
把函数名称sysdate改成getdate
-- 按钮父菜单ID(mysql)
-- SELECT @parentId := LAST_INSERT_ID();
-- 按钮父菜单ID(sqlserver)
-- 改成下边
-- 返回insertinto 语句后的主键值
declare @parentId int
set @parentId = @@IDENTITY;
