错误：列“ID”的类型UUID的，但表达BYTEA类型

问题描述：

@Entity 
public class Member { 
    @Id 
    private UUID id; 
    @Column(name = "member_external_id", unique = true, nullable = false) 
    private String memberExternalId; 
    @Column(name = "client_id", unique = true, nullable = false) 
    private String clientId; 
    @Column(name = "client_secret", unique = true, nullable = false) 
    private String clientSecret; 
    @Column(unique = true, nullable = false) 
    private String email; 
    private boolean active; 
    @Column(name = "created_at") 
    private LocalDateTime createdAt; 

    public Member() { 
     // required by JPA 
    } 
    .... 
}

当我部署我的OpenShift PostgreSQL的应用程序中，我看到下面的日志中的错误

OpenShift具有PostgreSQL的9.2版本。

enter image description here

，我使用连接到数据库的依赖性看起来像

<dependency> 
    <groupId>org.postgresql</groupId> 
    <artifactId>postgresql</artifactId> 
    <version>9.2-1003-jdbc4</version> 
</dependency>

有没有人见过这个问题？我不知道如何解决它。

尝试了所有，他们没有工作！ – daydreamer 2014-11-05 15:00:53

在这个问题上的任何更新？你能分享你如何解决它吗？ – klappvisor 2015-08-12 15:25:25

答

尝试增加类型注释到的UUID类型例如

@Type(type = "pg-uuid") 
@Column(name = "id", columnDefinition = "uuid") 
private UUID id;

我只是工作过去同样的错误

答

这是我如何解决它：

我添加上的EclipseLink JPA依赖 https://mvnrepository.com/artifact/org.eclipse.persistence/org.eclipse.persistence.jpa
我添加了一个转换器我的UUID

 
    @Id 
    @TypeConverter(name = "uuidConverter", dataType = Object.class, objectType = UUID.class) 
    private UUID uuid;

错误：列“ID”的类型UUID的，但表达BYTEA类型
