mssql-异常value '0000-00-00' can not be represented as java.sql.Date

Mysql开发中采用ResultSet取值時,不管是才用getString()还是用getDate()，或者getObject,均会拋出如题所述异常.查阅Mysql官方Bug咨询:

是因为日期型(Date或DateTime类型)字串为'000-00-00'时,MySQL预设处理方式是拋出异常(exception).只要将jdbc数据库连接字串作如下修改即可:

修改前jdbc连接字符串为:

jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8&characterSetResults=UTF-8

修改後jdbc连接字符串为 :

 jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull

原文如下:

Datetimes with all-zero components (0000-00-00 ...) — These values can not be represented reliably in Java. Connector/J 3.0.x always converted them to NULL when being read from a ResultSet.

Connector/J 3.1 throws an exception by default when these values are encountered as this is the most correct behavior according to the JDBC and SQL standards. This behavior can be modified using the zeroDateTimeBehavior configuration property. The allowable values are:

exception (the default), which throws an SQLException with an SQLState of S1009.

convertToNull, which returns NULL instead of the date.

round, which rounds the date to the nearest closest value which is 0001-01-01.

Starting with Connector/J 3.1.7, ResultSet.getString() can be decoupled from this behavior via noDatetimeStringSync=true (the default value is false) so that you can retrieve the unaltered all-zero value as a String. It should be noted that this also precludes using any time zone conversions, therefore the driver will not allow you to enable noDatetimeStringSync and useTimezone at the same time.
