Question

为了清理和重构一些代码，我创建了一个新工作区和新项目。我的项目设置如下：一个核心项目（Javaproject使用Maven进行依赖管理）和两个动态Web项目（JSF），它们共享来自核心项目的代码（类似于this SO-Post的设置）。我正在使用带有Hibernate和Primefaces的Wildfly 10。到目前为止，我所做的是将旧的凌乱项目中的基本类复制到新的核心项目，以便启动和运行应用程序。代码没有被触及，它在我的旧设置中工作正常。应用程序启动正常并导航到登录页面，但每次我按下登录按钮时都会收到以下异常：

Caused by: org.hibernate.AnnotationException: Unknown Id.generator: increment

org.hibernate.AnnotationException: Unknown Id.generator: increment实际上应该不会发生，因为所有内容都注释正常并且一直正常工作。有趣的是，DB-table也不会像实际应该那样自动创建。起初我认为这可能是由于碰撞了JPA之类的依赖项，因为在Web项目的已部署WEB-INF\lib文件夹中，我发现了一堆不必要的jars，如jboss *和hibernate *等。遗憾的是删除它们并没有解决问题

示范模型类：

@Entity
@Table(name = "user")
@NamedQuery(name = "User.findUserByEmail", query = "select u from User u where u.email = :email")
public class User implements Serializable
{
    public static final String FIND_BY_EMAIL = "User.findUserByEmail";
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(generator = "increment")
    @GenericGenerator(name = "increment", strategy = "increment")
    @Column(name = "PK_user_id")
    private int id;

    @OneToMany
    @JoinColumn(name = "FK_user_id")
    private List<ArticleList> articleLists;

    @Column(name = "user_email")
    private String email;

    @Column(name = "user_first_name")
    private String firstName;

    @Column(name = "user_hashed_password")
    private byte[] hashedPassword;

    @Column(name = "user_last_name")
    private String lastName;

    @Enumerated(EnumType.STRING)
    @Column(name = "user_role")
    private Role role;

    @Column(name = "user_salt")
    private byte[] salt;

    //getters and setters
}

为什么会发生这种情况的任何线索？提前谢谢

Answer 1

在反序列化时问题是byte[]到String转换。 SHA生成原始字节数组，无论编码如何，都无法保证任意byte[]将产生有效的String。因此，您的代码只能通过意外工作。
而不是byte[]使用String hashedPassword和salt。如果这样做，那么问题就是将byte[]映射到hibernate。

注意：保持使用increment生成主键的代码。

org.hibernate.AnnotationException：未知Id.generator：增量
