mysql中datetime类型字段为默认值0000-00-00 00:00:00怎么取出来

Answer 1

然后网上搜素了一下解决方案如下：原来是jdbc连接的问题 改成这样jdbc:mysql://localhost:3306/brilliant?user=conglin&password=conglin&useUnicode=true&characterEncoding=gbk&zeroDateTimeBehavior=convertToNullDatetimes with all-zero components (0000-00-00 ...) — These values can not be represented 关于所有Datetime类型由0组成的数据，这些值不能在java中被可靠的表示 reliably in Java. Connector/J 3.0.x always converted them to NULL when being read from a ResultSet. 当这些值正在从ResultSet容器中读取时候，Connector/J 3.0.x 一直把他们转换为NULL值。
