SpringBoot-JPA+AuditingEntityListener時區(qū)設(shè)置方式

第SpringBoot:JPA+AuditingEntityListener時區(qū)設(shè)置方式目錄JPA+AuditingEntityListener時區(qū)設(shè)置可在應(yīng)用配置中添加如下配置@EntityListeners(AuditingEntityListener.class)介紹@EntityListenersAuditingEntityListener.class

JPA+AuditingEntityListener時區(qū)設(shè)置

在SpringBoot項目中，如果應(yīng)用啟用了EnableJpaAuditing并且使用AuditingEntityListener對實體的創(chuàng)建時間、更新時間進(jìn)行自動審計，可能存在生成時間的時區(qū)和系統(tǒng)時區(qū)不一致的問題。

可在應(yīng)用配置中添加如下配置

將時區(qū)設(shè)定為指定時區(qū)：

perties.hibernate.jdbc.time_zone=GMT+8
