如何使用usertype在JPA中使用Hibernate持久保存JSR 310 java.time.LocalDateTime

2023年2月2日 262次阅读

我正在尝试使用usertype在
Java中使用Hibernate在Java 8中持久保存java.time.LocalDateTime.

我有一个注释如下的财产.

@Type(type = "org.jadira.usertype.dateandtime.threetenbp.PersistentLocalDateTime")
private java.time.LocalDateTime createdDateTime;

我已经为usertype添加了依赖项,如下所示.

compile 'org.jadira.usertype:usertype.extended:3.2.0.GA'
compile 'org.threeten:threetenbp:0.9'

但是,我有以下例外情况

stacktrace暗示ClassNotFound,但我添加了依赖’org.threeten：threetenbp：0.9′

我的问题

如何使用usertype在Hibernate中持久化JPA中的java.time.LocalDateTime？

最佳答案 它不起作用,因为您使用了错误的类型.对于JSR-310类,您应该使用org.jadira.usertype.dateandtime.threeten.PersistentLocalDateTime而不是org.jadira.usertype.dateandtime.threetenbp.PersistentLocalDateTime.

您不需要org.threeten：threetenbp：0.9依赖项.
