java - 错误 : column "id" is of type uuid but expression is of type bytea

Question

我的实体看起来像

@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
    }
    ....
}

当我使用 PostgreSQL 在 OpenShift 上部署我的应用程序时，我在日志中看到以下错误

OpenShift 拥有 PostgreSQL 9.2 版。

我用来连接数据库的依赖看起来像

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

有人见过这个问题吗？我不知道如何解决它。

尝试在 UUID 类型上添加类型注释 例如

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

我刚刚解决了同样的错误
