将Groovy应用程序连接到SQL服务器Express

Question

我按照下面的教程，但必须有一些重要的步骤，我没有知识，我们假设。

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" 

和下面的设置是错误上运行的应用程序命令弹出

ERROR context.GrailsContextLoader - Error executing bootstraps:

一直在这几个几天没有看到我的应用程序运行.....任何建议？

Answer 1

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

那是因为你的驱动程序在classpath中失踪。在SQL Server的情况下，您需要将jar复制到lib文件夹。

在其他像MySQL这样的情况下，你可以声明为maven依赖。

Answer 2

我们正在做与你一样的事情。 因此，我们在/ lib目录下有sqljdbc.jar。

在我们的DataSource.groovy中，我们有那么：

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

我记得刚的.jar是不够的，我想你需要一小部分安装到您的Windows/UNIX的目录如从这里：
