java.sql.SQLException: Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp
问题描述, 在java应用程序中,数据表中有记录的time字段(属性为timestamp)其值为:“0000-00-00 00:00:00”
程序使用select 语句从中取数据时出现以下异常:
java.sql.SQLException:Value '0000-00-00' can not be represented as java.sql.Date
这是因为 “0000-00-00 00:00:00”在mysql中是作为一个特殊值存在的,但是在Java中, java.sql.Date 会被视为 不合法的值,被JVM认为格式不正确。
解决办法:
在jdbc的url加上 zeroDateTimeBehavior参数:
datasource.url=jdbc:mysql://localhost:3306/pe?useUnicode=true&characterEncoding=gbk&zeroDateTimeBehavior=convertToNull
对于值为0000-00-00 00:00:00(默认值)的纪录,根据不同的配置,会返回不同的结果:
不配置:默认返回异常
zeroDateTimeBehavior=round 0001-01-01 00:00:00.0
zeroDateTimeBehavior=convertToNull null
