2 years ago 解决方法：
@TableName("`user`")
@Data
public class User {
private Long id;
private String name;
private Integer age;
private String email;
}schema-h2.sql
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`
(
id BIGINT NOT NULL COMMENT '主键ID',
name VARCHAR(30) NULL DEFAULT NULL COMMENT '姓名',
age INT NULL DEFAULT NULL COMMENT '年龄',
email VARCHAR(50) NULL DEFAULT NULL COMMENT '邮箱',
PRIMARY KEY (id)
);data-h2.sql
DELETE FROM `user`;
INSERT INTO `user` (id, name, age, email) VALUES
(1, 'Jone', 18, 'test1@baomidou.com'),
(2, 'Jack', 20, 'test2@baomidou.com'),
(3, 'Tom', 28, 'test3@baomidou.com'),
(4, 'Sandy', 21, 'test4@baomidou.com'),
(5, 'Billie', 24, 'test5@baomidou.com');application.yml

11 months ago 支持，你的问题只是h2数据库版本问题。 你的h2用什么版本呢？
当前使用版本(必填,否则不予处理)
MP 3.5.2
该问题是如何引起的？(确定最新版也有问题再提!!!)
更改spring boot版本
重现步骤(如果有就写完整)
在学习mybatis-plus-samples-master这个项目的时候,我自己动手做了一个demo 使用的是dependencyManagement的方式做module
您可以尝试将下面附件里的父工程的pom.xml的2.6.11</org.springframework.boot.version>改成2.7.x的版本
然后运行
报错信息
