將Groovy應用程序連接到SQL服務器Express

Question

我按照下面的教程，但必須有一些重要的步驟，我沒有知識，我們假設。

http://padcom13.blogspot.co.uk/2011/01/setting-up-sql-server-2008-express-to.html

下面

是我DataSource.groovy中

username = "sa" 
password = "" 
url = "jdbc:sqlserver://localhost:1433;databaseName=Sandpit" 
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver" 
dialect = "org.hibernate.dialect.SQLServerDialect" 

和下面的設置是錯誤上運行的應用程序命令彈出

ERROR context.GrailsContextLoader - Error executing bootstraps:

一直在這幾個幾天沒有看到我的應用程序運行.....任何建議？

Answer 1

的根本原因是Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'

那是因爲你的驅動程序在classpath中失蹤。在SQL Server的情況下，您需要將jar複製到lib文件夾。

在其他像MySQL這樣的情況下，你可以聲明爲maven依賴。

Answer 2

我們正在做與你一樣的事情。 因此，我們在/ lib目錄下有sqljdbc.jar。

在我們的DataSource.groovy中，我們有那麼：

dbCreate = "update" // one of 'create', 'create-drop','update' 
username = "dbo" 
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver" 
url = "jdbc:sqlserver://devdb02:1433;databaseName=my_database;" 

我記得剛的.jar是不夠的，我想你需要一小部分安裝到您的Windows/UNIX的目錄如從這裏：
