Grails的1.3.7映射到SQL Server的2K8日期列

Question

我們有一個傳統的Grails應用程序運行1.3.7和遇到問題映射到MSSQL服務器2K8表日期數據類型。

我找到了與sqlType:'date'映射它仍然得到以下錯誤，當它試圖加載實體錯誤util.JDBCExceptionReporter - 無法將「2013年7月24日」到時間戳。

增加了一個自定義的方言與延長SQLServerDialect下沒有區別

registerColumnType(Types.DATE, "date"); 

Answer 1

的Grails 1.3.7帶有休眠3.3.1 GA束。我認爲在這個版本的Hibernate沒有SQLServer2008Dialect，只有一個`SQLServerDialect這是良好的

2K和2K5版本

你必須從一個更高版本借用這個類，如this blog post

我解釋這裏重現類歸檔的緣故（從robert-reiz.com）

你必須添加

dialect = org.hibernate.dialect.SqlServer2008Dialect 

在Datasource.groovy`配置文件中，並使該類可用於您的類路徑

警告：在博客文章中，Hibernate的基礎版本是3.6.4，上面的代碼使用了不存在的SQLServer2005Dialect類在3.3.1 GA版本中。我修改上面的代碼（I使用SQLServerDialect），同時假設這些類是兼容機到考慮到這一點。我沒有檢查這個。
