Question

我有一个包含数据的Postgres sql数据库。我试图用我的Spring-Data-JPA项目插入Hibernate映射数据。我正在

ERROR: org.hibernate.engine.jdbc.spi.SqlExceptionHelper - ERROR: column "is_active" is of type bit varying but expression is of type oid

这是我的实体

@Entity
@Table(schema = "shard_1", name = "pages")
@XmlRootElement
@NamedQueries({ @NamedQuery(name = "Pages.findAll", query = "SELECT p FROM Pages p"),
        @NamedQuery(name = "Pages.findById", query = "SELECT p FROM Pages p WHERE p.id = :id"),
        @NamedQuery(name = "Pages.findByPageNumber", query = "SELECT p FROM Pages p WHERE p.pageNumber = :pageNumber"),
        @NamedQuery(name = "Pages.findByTitle", query = "SELECT p FROM Pages p WHERE p.title = :title"),
        @NamedQuery(name = "Pages.findBySectionId", query = "SELECT p FROM Pages p WHERE p.sectionId = :sectionId"),
        @NamedQuery(name = "Pages.findByVersionId", query = "SELECT p FROM Pages p WHERE p.versionId = :versionId"),
        @NamedQuery(name = "Pages.findByCreated", query = "SELECT p FROM Pages p WHERE p.created = :created"),
        @NamedQuery(name = "Pages.findByModified", query = "SELECT p FROM Pages p WHERE p.modified = :modified"),
        @NamedQuery(name = "Pages.findByPdfcontent", query = "SELECT p FROM Pages p WHERE p.pdfcontent = :pdfcontent") })
public class Pages implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(nullable = false)
    private Long id;
    @Column(name = "page_number")
    private Integer pageNumber;
    @Column(length = 2147483647)
    private String title;
    @Column(name = "section_id")
    private BigInteger sectionId;
    @Column(name = "version_id")
    private BigInteger versionId;
    @Lob
    @Column(name = "is_active")
    private Object isActive;
    @Temporal(TemporalType.TIMESTAMP)
    private Date created;
    @Temporal(TemporalType.TIMESTAMP)
    private Date modified;
    @Column(length = 2147483647)
    private String pdfcontent;
}

这是我的postgres表

CREATE TABLE shard_1.pages
(
    id bigint NOT NULL DEFAULT shard_1.id_generator(),
    page_number integer,
    title text COLLATE pg_catalog."default",
    section_id bigint,
    version_id bigint,
    is_active bit varying,
    created timestamp without time zone,
    modified timestamp without time zone,
    pdfcontent text COLLATE pg_catalog."default",
    CONSTRAINT pages_pkey PRIMARY KEY (id)
)
WITH (
    OIDS = FALSE
)
TABLESPACE pg_default;

ALTER TABLE shard_1.pages
    OWNER to root;

我尝试了Java数据类型boolean，string，char array，int，byte []但是失败了。我应该在这里使用is_active字段的数据类型是什么？

Answer 1

尝试删除@Lob，即：

@Column（name =“is_active”） private Boolean isActive;

并改变你的桌子'shard_1.pages'就像这样：

ALTER TABLE shard_1.pages DROP COLUMN is_active; ALTER TABLE shard_1.pagese ADD COLUMN is_active boolean;

Postgres Bit Variant等效数据类型在Java中
