当前使用版本(必填,否则不予处理)
Mybatis-plus 3.4.2 Mysql 8.0.29
该问题是如何引起的？(确定最新版也有问题再提!!!)
数据库建表后，使用IDEA插件MybatisX Generator代码生成器生成Entity、Service、Mapper 在ctrl中实现 service.getOne(queryWapper)执行始终提示找不到pass_word字段，在可视化工具或mysql命令行执行控制台输出查询语句得到结果正常。于是再次尝试修改字段pass_word为user_password后，接着提示下一个字段role_id找不到，于是将role_id改为rule_id依旧提示找不到。 核对数据库表字段与实体类、Mapper.xml文件对比一致。
重现步骤(如果有就写完整)
