基本上，我试图使一个简单的提升页面，我得到的错误是SQL错误：1054，SQL状态：42 S22错误是“字段列表”中的未知列“promotion0_.promo_type_id”
以下是模型类

package promotions.model;

import java.io.Serializable;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;

@Entity
@Table(name="promotion")
public class Promotion implements Serializable{

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="id")
private int id;
private String name;
private boolean active;
private boolean status;
@ManyToOne
@JoinColumn(name="promoType_id")
private Promo_Type promo_Type;
@ManyToOne
@JoinColumn(name="roomType_id")
private RoomType room_Types;


public Promotion() {

}
public Promotion(String name, boolean active, boolean status, Promo_Type promo_Type, RoomType room_Types) {
    super();
    this.name = name;
    this.active = active;
    this.status = status;
    this.promo_Type = promo_Type;
    this.room_Types = room_Types;
}
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public boolean isActive() {
    return active;
}
public void setActive(boolean active) {
    this.active = active;
}
public boolean isStatus() {
    return status;
}
public void setStatus(boolean status) {
    this.status = status;
}
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "promoType_id")
public Promo_Type getPromo_Type() {
    return promo_Type;
}

public void setPromo_Type(Promo_Type promo_Type) {
    this.promo_Type = promo_Type;
}

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "roomType_id")
public RoomType getRoom_Types() {
    return room_Types;
}
public void setRoom_Types(RoomType room_Types) {
    this.room_Types = room_Types;
}
@Override
public String toString() {
    return "Promotions [id=" + id + ", name=" + name + ", active=" + active + ", status=" + status + ", promo_Type="
            + promo_Type + ", room_Types=" + room_Types + "]";
}

}

package promotions.model;

import java.io.Serializable;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name="roomType")
public class RoomType implements Serializable{

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="roomType_id")
private int id;
private String name;

@OneToMany(mappedBy="room_Types", cascade= CascadeType.ALL,fetch= FetchType.LAZY)
private Collection<Promotion>promotions;



public RoomType() {

}

public RoomType(String name, Collection<Promotion> promotions) {
    super();
    this.name = name;
    this.promotions = promotions;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public Collection<Promotion> getPromotions() {
    return promotions;
}

public void setPromotions(Collection<Promotion> promotions) {
    this.promotions = promotions;
}




}

下面是另一个模型类

package promotions.model;

import java.io.Serializable;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;

@Entity
@Table(name="promoType")
public class Promo_Type implements Serializable{
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="promoType_id")
private int id;
private String name;
private double discount;
@OneToMany(mappedBy="promo_Type", cascade= CascadeType.ALL,fetch= FetchType.LAZY)
private Collection<Promotion>promotions;


public Promo_Type() {

}
public Promo_Type(String name, double discount, Collection<Promotion>      promotions) {
    super();
    this.name = name;
    this.discount = discount;
    this.promotions = promotions;
}
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public double getDiscount() {
    return discount;
}
public void setDiscount(double discount) {
    this.discount = discount;
}
public Collection<Promotion> getPromotions() {
    return promotions;
}
public void setPromotions(Collection<Promotion> promotions) {
    this.promotions = promotions;
}

}
下面是mysql查询

CREATE DATABASE `promotiondb`;

use promotiondb;

CREATE TABLE `promoType` (
  `promoType_id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(45) NOT NULL,
  `discount` DOUBLE NOT NULL,
  PRIMARY KEY (`promoType_id`)
);

CREATE TABLE `roomType` (
  `roomType_id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(70) NOT NULL,
   PRIMARY KEY (`roomType_id`)
);

CREATE TABLE `promotion` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(45) NULL,
  `status` TINYINT(1) NULL,
  `active` TINYINT(1) NULL,
  `promoType_id` int(11) NOT NULL,
  `roomType_id` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `fk_promoType` (`promoType_id`),
  KEY `fk_roomType` (`roomType_id`),
  CONSTRAINT `fk_roomType` FOREIGN KEY (`roomType_id`) REFERENCES `roomType` (`roomType_id`),
  CONSTRAINT `fk_promoType` FOREIGN KEY (`promoType_id`) REFERENCES `promoType` (`promoType_id`)
);

下面是错误，SQL错误：1054，SQL状态：42 S22，“字段列表”中的“升级类型标识”未知。错误34768 --- [nio-8080-exec-3] o. h.引擎.jdbc.spi.SqlExceptionHelper：“字段列表”中的列“promotion0_.promo_type_id”未知

您的问题来自application.properties于SpringBoot在数据库中命名列时使用的config（www.example.com）。实际上，如果要解决这个问题，您必须避免在列名中使用大写字母，或者在application.properties中更改命名策略，并使用

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

遇到相同的错误，在 application.properties 上从

spring.jpa.properties.hibernate.hbm2ddl.auto: none

至
