無法使用spring.net在asp.net mvc3應用程序中打開數據庫（sqlite）

Question

我在寫一個asp.net mvc3 web應用程序。我想使用一個sqlite數據庫。不幸的是，我得到一個SqliteException，說「無法打開數據庫」。

彈簧版本：1.3.2

NHibernate的-版本：3.2

DbProvider/ConnectionString的：

<db:provider id="employeesDbProvider" 
      provider="SQLite-1.0.72" 
      connectionString="Data Source=.\Database\Employees.db3;Version=3;"> 
</db:provider> 

堆棧跟蹤：

bei System.Data.SQLite.SQLite3.Open(String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool) in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLite3.cs:Zeile 239. 
bei System.Data.SQLite.SQLiteConnection.Open() in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteConnection.cs:Zeile 1022. 
bei NHibernate.Connection.DriverConnectionProvider.GetConnection() 

我甚至嘗試將DataSource設置爲絕對路徑（C：\ temp \ database \ Employees.db3），但引發了相同的SqLiteException。

更新：顯示錯誤頁面

Answer 1

我做了一個快速測試使用SQLite，Spring.Net和但它失敗，出現同樣的錯誤，當我用斜槓，而不是反斜槓在連接字符串中它神奇地開始工作。

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72" 
    connectionString="Data Source=c:/temp/Database/Sample.db3;Version=3;"> 
</db:provider> 

編輯： 我測試了一下再找出該文件，如果我用點前綴，例如存儲./Employees.db3。在IISExpress中它存儲在C:\Program Files (x86)\IIS Express很可能不是你所期望的。

在IIS7中，它僅僅因爲Unable to open the database file錯誤而失敗，因爲它試圖寫入Temporary ASP.NET Files文件夾。

最安全的辦法是使用

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72" 
    connectionString="Data Source=|DataDirectory|Sample.db3;Version=3;"> 
</db:provider> 

至極是你的MVC應用程序的文件夾App_Data。

我爲我的測試使用了SQLite 1.0.80.0。請記住，SQLite不會創建該目錄並需要ACL寫入權限。
