Question

在申请失业期间，我有一些JPA @Temporal（TemporalType.DATE）注释的问题。所以我创建了spring数据+ postgres 9.5 + hibernate 4.3.10 app并将 hbm2ddl.auto 设置为'验证'。

hibernate.hbm2ddl.auto = validate

这是实体：

@Entity
@Table(name = "locomotive")
public class LocomotiveEntity {

    private Long locomotiveId;
    @Column(name = "status")
    private int status;
    @Temporal(TemporalType.DATE)
    private java.util.Date constructionYear;
...

我还使用此脚本创建了 locomotive 表：

CREATE TABLE "locomotive"
(
    "locomotiveId"  bigserial PRIMARY KEY,
    "status" integer NOT NULL,
    "constructionYear" DATE NOT NULL
);

但我在失业期间看到例外：

Caused by: org.hibernate.HibernateException: Wrong 
column type in public.constructionYear for column constructionYear.
 Found: date, expected: timestamp

所以我的db中有'DATE'类型列，'DATE'是java类型。我做错了什么？

Answer 1

尝试使用TemporalType.TIMESTAMP，如下所示：

 @Temporal(TemporalType.TIMESTAMP)
 private Date constructionYear;

postgresql jpa hibernate异常：找到：date，expected：timestamp
