Hibernate MSSQL datetime2映射 [英] Hibernate MSSQL datetime2 mapping

问题描述

我有一个存储过程，该存储过程返回数据库中数据类型为datetime2以及Java文件中Date为数据的列。当我尝试在从数据库获取的时间上调用getTime（）时。返回的时间为19994321211毫秒，相当于IST 2015年5月4日星期一。理想情况下，它应返回的时间为2015-05-04 15:21:52的毫秒数，因为这是直接执行过程时数据库中显示的时间。

I have a stored procedure which is returning a column having datatype as datetime2 in database and Date in Java file. When I am trying to call getTime() on that obtained time from database. It's returning 19994321211 millisecond which is equivalent to Mon May 04 00:00:00 IST 2015. ideally it should return milliseconds of 2015-05-04 15:21:52 as this is the time shown in database when procedure is executed directly.

由于我是Hibernate的新手，所以我无法理解该问题是否与hibernate映射有关，或者我错过了其他事项。

As I am new to Hibernate , I am unable to understand if the issue is related to hibernate mapping or something else I am missing out.

<hibernate-mapping>
   <sql-query name="getMLC">
            <return-scalar column="mlcid" type="int" />
            <return-scalar column="completionTime" type="date" />
            { call lsc.MLC_Get(:ABC, :XYZ, :ErrorCode)}
    </sql-query>
</hibernate-mapping>

class Mlc implements java.io.Serializable {

    private Integer mlcid;
    private Date completionTime;
    // getter and setter
}

推荐答案

尝试像这样注册新的驱动程序：

Try registering a new Driver like this:

public class DateTime2SQLServerDialect extends SQLServer2008Dialect {

   public DateTime2SQLServerDialect () {
      super();
      registerColumnType(Types.DATE, "datetime2");
   }
}

，然后改用此方言：

<property name="hibernate.dialect">my.package.DateTime2SQLServerDialect</property>

也可以尝试更改此内容：

Also try changing this:

<return-scalar column="completionTime" type="date" />

为此：

<return-scalar column="completionTime" type="timestamp" />
