关于如何解决此错误有什么想法吗？我将 Spring JPA 与 Hibernate 一起使用。下面是必要的详细信息。
实体类别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
}
用户的实体类：
@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：
堆栈跟踪非常大。我将整个堆栈跟踪粘贴到下面以供参考和快速TL;DR：
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
完整的堆栈跟踪如下：

UPDATE:
我将 Ways 实体类更新为以下内容，但仍然出现错误：
@Entity
@Table(name = "ways")
@Cacheable
public class Way implements Serializable {

private static final long serialVersionUID = -7941769011539363185L;

@Column(name = "id")
private Long id;
/**

@Column(name = "way_id")
private Long wayId;
/**

@Column(name = "version")
