使用 Hibernate 的异常

Question

请帮帮我。

在插入表数据时崩溃，列 setCreateDate。谁知道这个错误是什么，为什么不可能写一个时间戳DateTime对象？？？？

Answer 1

您可能在createDate 映射上缺少@Temporal 注释。应该是这样的

@Temporal(TemporalType.TIMESTAMP) 
private Date createDate;

此映射需要timestamp 类型的数据库列（根据您的需要，它可以是date 或任何类似类型）。

Answer 2

谢谢大家，正如@StanislavL 所写，转错类型，表列created_ts bigint NOT NULL DEFAULT fn_now_as_bigint()
