spring – 带有Hibernate 5的Oracle 12c Identity列

Spring 前端之家
前端之家收集整理的这篇文章主要介绍了spring – 带有Hibernate 5的Oracle 12c Identity列，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在尝试使用Hibernate-5.0.0.CR4的Oracle 12c Identity列功能.我在Spring引导application.properties中使用了以下属性：

spring.jpa.hibernate.dialect=org.hibernate.dialect.Oracle12cDialect
spring.datasource.driverClassName=oracle.jdbc.OracleDriver

从Oracle12cDialect的source code开始,它似乎支持标识列.但是在尝试将记录插入名为user_preferences的表时,我收到以下错误：

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

import org.hibernate.envers.Audited;
import org.hibernate.envers.RelationTargetAuditMode;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

import lombok.Data;

@Entity
@Table(name = "user_preferences")
@Data
@JsonIgnoreProperties(value = { "prefId" })
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
public class UserPreference {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "pref_id")
    private Long prefId;

    @Column(nullable = false)
    private String key;

    @Column(nullable = false)
    private String preference;

    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    public UserPreference() {
    }

    public UserPreference(String key,String preference,User user) {
        this.key = key;
        this.preference = preference;
        this.user = user;
    }

}

我得到的例外情况：

如果有方法可以使用标识列而不使用数据库序列,请告诉我.

最佳答案
当您指定GenerationType.IDENTITY时,似乎Hibernate 5.0.X会尝试从数据库中获取ID值.使用适当的getXXX从java ResultSet中检索此值,具体取决于您用于声明ID的类型. resultSet.getString(columnIndex)或resultSet.getRowId(columnIndex)在我的情况下工作,但RowId不能在JPA bean中使用.

如果你尝试将它更改为字符串它应该工作,即使它看起来像我的错误：

@Id
@Column(name="PRD_ID")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private String prdId;
