I have a task to migrate to Spring Boot 3.x (from Spring Boot 2.6.5) and I chose OpenRewrite tool to help me with this task. After all the migration changes were done, running the application locally gives me the error below.

Upon searching stackoverflow regarding this issue I found below issues which I used as reference
Same issue with no fix Getting property [djob] not found on entity [com.xxx.JobsDeviceIds] after upgrading to Spring framework 3.2.2
Same issue with no fix Problem with Composite Primary Keys in JPA (Migrating from hibernate-jpa 2.1 to jakarta-persistence 3.1.0)
Almost similar issue but fix doesn't apply to my scenario Spring 3 with Hibernate 6.2+ Application startup fail - mappingModelPart is null
I also tried adding breakpoint in MappingException class and saw below error message. I tried modifying custAccId to 'id' but it doesn't fix the issue.
property [id] not found on entity [com.foo.mysvc.customerdata.model.CustomerAccount]
Below is the entity class in question. Any help is greatly appreciated.
package com.foo.mysvc.customerdata.model;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.ToString;
import org.hibernate.annotations.CreationTimestamp;
import org.hibernate.annotations.UpdateTimestamp;
import jakarta.persistence.*;
import java.time.LocalDateTime;
@Entity
@Table(name="CUSTOMER_ACCOUNT")
@Data
public class CustomerAccount {
@Id
@Column(name="CUST_ACC_ID")
private String custAccId; //pk
@Column(name = "CUSTOMER_INFO_ID")
private Long customerInfoId;
@ToString.Exclude
@EqualsAndHashCode.Exclude
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "CUSTOMER_INFO_ID", referencedColumnName = "id", insertable=false, updatable=false)
private CustomerInfo customerInfo; //fk
@Column(name="INTERNAL_ACC_NUMBER")
private String internalAccNumber;
@Column(name="MASKED_NUMBER")
private String maskedNumber;
@Column(name="PRODUCT_DESCRIPTION")
private String productDesc;
@Column(name="ACC_TYPE")
private String accountType;
@Column(name="BASE_CCY")
private String baseCurrency;
@Column(name="ACTIVE")
private boolean active;
@CreationTimestamp
private LocalDateTime createdAt;
@UpdateTimestamp
private LocalDateTime updatedAt;
}```
Update: my colleague found the issue and the culprit was an @SqlResultSetMapping annotation in one of the entity classes but not being used to any named query.
I hope this helps to anyone facing the same issue. Hibernate 6 added validations to unused mapping annotations so you can check those because hibernate doesn't display helpful error message at all for these type of exceptions. Could have just displayed an error "Result set mapping annotation is declared but unused" or something similar.
