自动建表代码：
package com.cjh.springboot03.entity;
import lombok.Data;
import javax.persistence.*;
/**
* @author
* @site
* @company
* @create 2019-11-13 16:37

@Data
@Entity
@Table(name ="t_springboot_book_2019")
public class Hbook {
@Id
@GeneratedValue
private Integer bid;
@Column(length = 100)
private String bname;
@Column
private Float price;
}
运行项目它会自动把表建好。
