java – Hibernate：无法反序列化

关于我如何解决这个错误的任何想法？我正在使用 Spring JPA与Hibernate.下面有必要的细节.

实体类1：

@Entity
@Table(name = "ways")
@TypeDef(name = "hstore",typeClass = HstoreUserType.class)
@Cacheable
public class Way {

    /**
     * Primary key for the row in table.
     */
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    /**
     * The ID to represent it across the system.
     * Used for preserving historical information. 
     */
    @Column(name = "way_id")
    private Long wayId;

    /**
     * The version of the way this Object represents. 
     */
    @Column(name = "version")
    private Integer version;


    /**
     * The {@link User} that edited this version. 
     */
    @OneToOne
    @PrimaryKeyJoinColumn(name = "user_id")
    private User user;

    /**
     * Timestamp when this version of the Way was edited.
     */
    @Column(name = "tstamp")
    @Temporal(TemporalType.TIMESTAMP)
    private Date timestamp;

    /**
     * The changeset that this version of the way belongs to. 
     */
    @Column(name = "changeset_id")
    private Long changesetId;

    /**
     * All the tags this Way contains. 
     */
    @Type(type = "hstore")
    @Column(name = "tags",columnDefinition = "hstore")
    private Object2ObjectOpenHashMap<String,String> tags = new Object2ObjectOpenHashMap<String,String>(); 

    @Column(name = "bBox")
    private Geometry bBox;

    @Column(name = "linestring")
    private Geometry linestring;

    @Column(name = "nodes")
    private Long[] nodes;

    // getters and setters
}

用户实体类：

@Entity
@Table(name = "users")
@Cacheable
public class User {

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

    @Column(name = "name",unique = true)
    private String name;

    // getters and setters

}

和堆栈跟踪：

堆栈跟踪很大.我正在粘贴整个堆栈跟踪以供参考和快速TL; DR在这里：

javax.persistence.PersistenceException: org.hibernate.type.SerializationException: could not deserialize
Caused by: org.hibernate.type.SerializationException: could not deserialize
Caused by: java.io.StreamCorruptedException: invalid stream header: 30313033

全堆栈跟踪如下：

更新：

我更新了Ways实体类到以下,但仍然出现错误：

@Entity
@Table(name = "ways")
@Cacheable
public class Way implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = -7941769011539363185L;

    /**
     * Primary key for the row in table.
     */
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    /**
     * The ID to represent it across the system.
     * Used for preserving historical information. 
     */
    @Column(name = "way_id")
    private Long wayId;

    /**
     * The version of the way this Object represents. 
     */
    @Column(name = "version")
    private Integer version;


    /**
     * The {@link User} that edited this version. 
     */
    @OneToOne
    @PrimaryKeyJoinColumn(name = "user_id")
    private User user;

    /**
     * Timestamp when this version of the Way was edited.
     */
    @Column(name = "tstamp")
    @Temporal(TemporalType.TIMESTAMP)
    private Date timestamp;

    /**
     * The changeset that this version of the way belongs to. 
     */
    @Column(name = "changeset_id")
    private Long changesetId;

    /**
     * All the tags this Way contains. 
     */
    @Column(name = "tags")
    private String tags; 

    @Column(name = "bBox")
    private Geometry bBox;

    @Column(name = "linestring")
    private Geometry linestring;

    @Column(name = "nodes")
    @ElementCollection(targetClass=Long.class)
    private List<Long> nodes;

解决方法

这个问题是在不能反序列化的情况下发生的(谢谢,上尉Captain).在您的实体映射中,以下内容可疑：

@Type(type = "hstore")
@Column(name = "tags",columnDefinition = "hstore")
private Object2ObjectOpenHashMap<String,String>(); 

@Column(name = "bBox")
private Geometry bBox;

@Column(name = "linestring")
private Geometry linestring;

我的建议是要查看几何和Object2ObjectHashMap类 – 检查它们是否是可序列化的,它们的所有字段也可以序列化,也可以用transient关键字标记.此外,如果你在这里发布这些课程,这可能有帮助. HstoreUserType类列表也可能有帮助.
