表 “stock” 不存在 jpa 和 spring-boot

问：

一切正常，直到我在“Stock”类中使用注释@ManyToOne，它生成了错误：

“原因：java.sql.SQLSyntaxErrorException：表'libraries.stock'不存在”

类“Stock”的实现：

import java.util.List;
import javax.persistence.*;
import lombok.Data;
@Entity
@Table(name="stock")
@Data
public class Stock {
@EmbeddedId
private stockid id;

private int quantity;
public Stock(int qq) {
    this.quantity = qq;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "book_id")
private Book book ;


@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "library_id")
private Library library ;   
}
