快速上手Mybatis-plus结构构建过程

package com.example.jsr303.entity;

import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

import java.io.Serializable;

/**
 * 学习测试JSR303
 */

@Data
@TableName("test")
public class TestEntity implements Serializable {

    //忽略掉 设置序列化和反序列化的serialVersionUID
    //想了解一下可以去这篇博客 https://blog.csdn.net/qq_45503106/article/details/107950914
    private static final long serialVersionUID = 1L;

    /**
     * test表主键ID
     */
    @TableId
    private Integer id;
    /**
     *  姓名
     */
    private String name;

    /**
     * 邮箱
     */
    private String email;

}
