Hibernate学习笔记：基础模型类

根据业务建模型时，有一些字段基本每个表都是需要的，如下表：

package com.company.jelly.model;

import javax.persistence.EntityListeners;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;
import javax.persistence.Version;

import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.jpa.domain.support.AuditingEntityListener;

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public abstract class BaseModel {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    protected Long id;

    @CreatedDate
    private Long createTimestamp;

    @LastModifiedDate
    private Long updateTimestamp;

    @Version
    private Long version;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public Long getCreateTimestamp() {
        return createTimestamp;
    }

    public void setCreateTimestamp(Long createTimestamp) {
        this.createTimestamp = createTimestamp;
    }

    public Long getUpdateTimestamp() {
        return updateTimestamp;
    }

    public void setUpdateTimestamp(Long updateTimestamp) {
        this.updateTimestamp = updateTimestamp;
    }

    public Long getVersion() {
        return version;
    }

    public void setVersion(Long version) {
        this.version = version;
    }

}

需要说明的是需要在SpringBoot启动类上面添加@EnableJpaAuditing注解
