Spring 3 with Hibernate 6.2+ Application startup fail - mappingModelPart is null

问题

我有一个Java Spring Boot应用程序（Spring Boot 3.1.0），我正在尝试更新其中的Hibernate。升级的原因是在较旧的版本中遇到了应用程序崩溃的错误，并希望查看较新的版本是否修复了这个问题。
从6.2.0开始的任何版本似乎在启动时导致应用程序崩溃，显示以下错误：

在此更新之前没有问题。这些版本是否有新的内容可能会引起此问题，例如新属性或额外的要求？

I have a Java Spring Boot app (Spring boot 3.1.0) for which I am trying to update hibernate for. The reason for the upgrade being that with the older versions I have encountered application braking bugs and wanted to see if the newer versions fix that.
Any version starting from 6.2.0 seems to crash the app at startup with the following error:

Prior to this update there was no issue. Is there something new with these versions that could cause this, maybe a new property or extra requirements?

几天前，当我们将一个应用程序从Spring Boot 2.7.0与Spring Data JPA（Hibernate Core 5.6.9-Final）迁移到Spring Boot 3.1.0（Hibernate Core 6.2.2-Final）时，我们偶然发现了相同的错误，如下所示：

看起来在我们的情况下，错误隐藏在一个 DiscountEntity 类中，该类声明了比其私有键 DiscountEntityPK 类中声明的 @Id 字段更多的 @Id 字段。因此，如您在 DiscountEntityPK.java 中所见，尽管复合私有键由2个列组成：

package com.manios.product.discount;

import java.io.Serializable;
import java.util.Objects;
import jakarta.persistence.Column;
import jakarta.persistence.Id;

public class DiscountEntityPK implements Serializable {
    private String companyId;
    private long discountId;

    @Column(name = "company_id", nullable = false, length = 2)
    @Id
    public String getCompanyId() {
        return companyId;
    }

    public void setCompanyId(String companyId) {
        this.companyId = companyId;
    }

    @Column(name = "discount_id", nullable = false)
    @Id
    public long getDiscountId() {
        return discountId;
    }

    public void setDiscountId(long discountId) {
        this.discountId = discountId;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        DiscountEntityPK that = (DiscountEntityPK) o;
        return discountId == that.discountId &&
                Objects.equals(companyId, that.companyId);
    }

    @Override
    public int hashCode() {

        return Objects.hash(companyId, discountId);
    }
}

实际的实体类 DiscountEntity.java 却有2个使用 @Id 注解标记的额外字段（在代码中搜索 INCORRECT ANNOTATION）：

package com.manios.product.discount;

import java.sql.Date;
import java.util.Objects;
import jakarta.persistence.Basic;
import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.IdClass;
import jakarta.persistence.Table;

@Entity
@Table(name = "discount")
@IdClass(DiscountEntityPK.class)
public class DiscountEntity {
  private String companyId;
  private long discountId;
  private String discountType;
  private Date fromDate;
  private Date toDate;
  private String discountText;
  private long priority;
  private long discountLevel;

  @Id
  @Column(name = "company_id", nullable = false, length = 2)
  public String getCompanyId() {
    return companyId;
  }

  public void setCompanyId(String companyId) {
    this.companyId = companyId;
  }

  @Id
  @Column(name = "discount_id", nullable = false)
  public long getDiscountId() {
    return discountId;
  }

  public void setDiscountId(long discountId) {
    this.discountId = discountId;
  }

  @Basic
  @Column(name = "discount_type", nullable = false, length = 2)
  public String getDiscountType() {
    return discountType;
  }

  public void setDiscountType(String discountType) {
    this.discountType = discountType;
  }

  @Basic
  @Column(name = "from_date", nullable = false)
  public Date getFromDate() {
    return fromDate;
  }

  public void set

It seems that in our case the error was hidden in the fact that one `DiscountEntity` class was declaring more `@Id` fields than the ones declared in its  private key `DiscountEntityPK` class. Therefore as you can see in `DiscountEntityPK.java`, although the composite private key consists of 2 columns:
```java
package com.manios.product.discount;
import java.io.Serializable;
import java.util.Objects;
import jakarta.persistence.Column;
import jakarta.persistence.Id;
public class DiscountEntityPK implements Serializable {
private String companyId;
private long discountId;
@Column(name = &quot;company_id&quot;, nullable = false, length = 2)
@Id
public String getCompanyId() {
return companyId;
}
public void setCompanyId(String companyId) {
this.companyId = companyId;
}
@Column(name = &quot;discount_id&quot;, nullable = false)
@Id
public long getDiscountId() {
return discountId;
}
public void setDiscountId(long discountId) {
this.discountId = discountId;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
DiscountEntityPK that = (DiscountEntityPK) o;
return discountId == that.discountId &amp;&amp;
Objects.equals(companyId, that.companyId);
}
@Override
public int hashCode() {
return Objects.hash(companyId, discountId);
}
}

the actual entity class, DiscountEntity.java, had 2 more fields annotated with the @Id annotation (search in the code for INCORRECT ANNOTATION)

package com.manios.product.discount;

import java.sql.Date;
import java.util.Objects;
import jakarta.persistence.Basic;
import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.IdClass;
import jakarta.persistence.Table;

@Entity
@Table(name = &quot;discount&quot;)
@IdClass(DiscountEntityPK.class)
public class DiscountEntity {
  private String companyId;
  private long discountId;
  private String discountType;
  private Date fromDate;
  private Date toDate;
  private String discountText;
  private long priority;
  private long discountLevel;

  @Id
  @Column(name = &quot;company_id&quot;, nullable = false, length = 2)
  public String getCompanyId() {
    return companyId;
  }

  public void setCompanyId(String companyId) {
    this.companyId = companyId;
  }

  @Id
  @Column(name = &quot;discount_id&quot;, nullable = false)
  public long getDiscountId() {
    return discountId;
  }

  public void setDiscountId(long discountId) {
    this.discountId = discountId;
  }

  @Basic
  @Column(name = &quot;discount_type&quot;, nullable = false, length = 2)
  public String getDiscountType() {
    return discountType;
  }

  public void setDiscountType(String discountType) {
    this.discountType = discountType;
  }

  @Basic
  @Column(name = &quot;from_date&quot;, nullable = false)
  public Date getFromDate() {
    return fromDate;
  }

  public void setFromDate(Date fromDate) {
    this.fromDate = fromDate;
  }

  @Basic
  @Column(name = &quot;to_date&quot;, nullable = false)
  public Date getToDate() {
    return toDate;
  }

  public void setToDate(Date toDate) {
    this.toDate = toDate;
  }

  @Basic
  @Column(name = &quot;disc_text&quot;, nullable = false, length = 240)
  public String getDiscountText() {
    return discountText;
  }

  public void setDiscountText(String discountText) {
    this.discountText = discountText;
  }

  //     ------------------------
  @Id // &lt;-- INCORRECT ANNOTATION. This should be @Basic instead
  @Column(name = &quot;priority&quot;, nullable = false)
  public long getPriority() {
    return priority;
  }

  public void setPriority(long priority) {
    this.priority = priority;
  }

  //     ------------------------
  @Id // &lt;-- INCORRECT ANNOTATION. This should be @Basic instead
  @Column(name = &quot;discount_level&quot;, nullable = false)
  public long getDiscountLevel() {
    return discountLevel;
  }

  public void setDiscountLevel(long discountLevel) {
    this.discountLevel = discountLevel;
  }

  @Override
  public boolean equals(Object o) {
    if (this == o) {
      return true;
    }
    if (o == null || getClass() != o.getClass()) {
      return false;
    }
    DiscountEntity that = (DiscountEntity) o;
    return discountId == that.discountId &amp;&amp;
            Objects.equals(companyId, that.companyId) &amp;&amp;
            Objects.equals(discountType, that.discountType) &amp;&amp;
            Objects.equals(fromDate, that.fromDate) &amp;&amp;
            Objects.equals(toDate, that.toDate) &amp;&amp;
            Objects.equals(priority, that.priority) &amp;&amp;
            Objects.equals(discountLevel, that.discountLevel);
  }

  @Override
  public int hashCode() {

    return Objects
            .hash(companyId, discountId, discountType, fromDate, toDate, priority, discountLevel);
  }
}

In order to find out we had to explicitly debug and add breakpoints in the MappingMetamodelImpl class. After replacing the @Id annotation with @Basic annotation in columns &quot;discount_level&quot; and &quot;priority&quot; the problem was fixed. I hope this helps!
