java - 无法预部署处于无效状态的 PersistenceUnit [PU] [DeployFailed]

Question

我使用 EclipseLink 作为我的 JPA 提供程序。我的应用程序工作正常，但最近在部署应用程序时出现错误，并且它不再工作。我是 JPA 新手，尽管我已阅读日志，但我无法理解发生了什么。它与 EclipseLink-93 和 EclipseLink-41 异常相关。有人可以帮助我吗？预先感谢您。

Exception [EclipseLink-93] (Eclipse Persistence Services - 2.6.3.qualifier): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: The table [CONTACT] is not present in this descriptor.
Descriptor: RelationalDescriptor(science.softdev.SongPromoter.model.Album --> [DatabaseTable(ALBUM)])

Exception [EclipseLink-41] (Eclipse Persistence Services - 2.6.3.qualifier): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: A non-read-only mapping must be defined for the sequence number field.
Descriptor: RelationalDescriptor(science.softdev.SongPromoter.model.Album --  [DatabaseTable(ALBUM)])

这是我的相册和联系人类的代码:

package science.softdev.SongPromoter.model;


import javax.persistence.*;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.UUID;

@Entity
public class Album {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int idAlbum;
private String albumUUID = UUID.randomUUID().toString();
private String name;
private String author;
private boolean active = true;
private String simplifiedDate;
private String zipUUID = UUID.randomUUID().toString();
private String description = "";

public int getIdAlbum() {
    return idAlbum;
}

public void setIdAlbum(int idAlbum) {
    this.idAlbum = idAlbum;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getZipUUID() {
    return zipUUID;
}

public void setZipUUID(String zipUUID) {
    this.zipUUID = zipUUID;
}

public String getSimplifiedDate() {
    return simplifiedDate;
}

public void setSimplifiedDate(String simplifiedDate) {
    this.simplifiedDate = simplifiedDate;
}

public boolean isActive() {
    return active;
}

public void setActive(boolean active) {
    this.active = active;
}

public void setAlbumUUID(String albumUUID) {
    this.albumUUID = albumUUID;

public String getAuthor() {
    return author;

private String cover;
private String coverUUID = UUID.randomUUID().toString();

public String getCoverUUID() {
    return coverUUID;
}

public void setCoverUUID(String coverUUID) {

public String getAlbumUUID() {
    return albumUUID;

public String getCover() {
    return cover;
}

public void setCover(String cover) {

}

public void setMixes(List<Mix> mixes) {
    this.mixes = mixes;
}

@OneToMany(mappedBy="album",cascade = CascadeType.ALL)
private List<Mix> mixes = new ArrayList<Mix>();

@OneToMany(mappedBy="author",cascade = CascadeType.ALL)
private List<Review> reviews = new ArrayList<Review>();

public List<Review> getReviews() {
    return reviews;
}

public void setReviews(List<Review> reviews) {
    this.reviews = reviews;
}

public String getName() {
    return name;
}

    this.name = name;
}

public List<Mix> getMixes() {
    return mixes;
}

public void setMixes(ArrayList<Mix> mixes) {
    this.mixes = mixes;

}

这是 Contact 类:

package science.softdev.SongPromoter.model;

import javax.persistence.*;
import java.util.ArrayList;
import java.util.List;
import java.util.UUID;


@Entity
public class Contact {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int idContact;
private String name;
private String email;
private String contactUUID = UUID.randomUUID().toString();
private boolean active;

@OneToMany(mappedBy = "author")
private List<Review> reviews = new ArrayList<Review>();

public List<Review> getReviews() {
    return reviews;
}

public void setReviews(List<Review> reviews) {
    this.reviews = reviews;
}

public boolean isActive() {
    return active;
}

public void setActive(boolean active) {
    this.active = active;
}

public String getContactUUID() {
    return contactUUID;
}

public void setContactUUID(String contactUUID) {
    this.contactUUID = contactUUID;
}

public int getIdContact() {
    return idContact;
}

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

public String getName() {
    return name;
}

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

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}
}

Answer 1

我最终通过将持久性提供程序从 EclipeLink 更改为 Hibernate(在 Payara 服务器 4.1 中运行)解决了这个问题。我在互联网上找不到与此问题相关的任何可以帮助我解决问题的资源。它可能是 EclipseLink 2.6.3 的一个未报告的错误，因为只需切换 JPA 提供程序即可解决该问题。
