MONO使用SQLITE + Nhibernate

因某项目需移动到JEXUS上,该项目采用的是SQLITE + Nhibernate结构

在移植的过程中出现了一些问题,特此记录

首先System.Data.Sqlite在MONO下是不能用的

并且Nhibernate的配置文件引用的驱动类NHibernate.Driver.SQLite20Driver是不支持的

所以我们要对以上几点进行修改

1. 添加 MonoSQLiteDriver 类

public class MonoSQLiteDriver : NHibernate.Driver.ReflectionBasedDriver  
{  
        public MonoSQLiteDriver() 
            : base(
            "Mono.Data.Sqlite",
            "Mono.Data.Sqlite",  
            "Mono.Data.Sqlite.SqliteConnection",  
            "Mono.Data.Sqlite.SqliteCommand")  
    {  
    }  

    public override bool UseNamedPrefixInParameter {  
        get {  
            return true;  
        }  
    }  

    public override bool UseNamedPrefixInSql {  
        get {  
            return true;  
        }  
    }  

    public override string NamedPrefix {  
        get {  
            return "@";  
        }  
    }  

    public override bool SupportsMultipleOpenReaders {  
        get {  
            return false;  
        }  
    }  
}  

  

2. 将hibernate.cfg.xml 里的connection.driver_class节点的值,改成步骤1里的类, 即 YourNameSpace.MonoSqliteDriver, AssemblyName

如: xxxxx.MonoSqliteDriver, xxxxxxx

如果使用FluentNHibernate, 还需要如下

public class MonoSQLiteConfiguration : PersistenceConfiguration
{
    public static MonoSQLiteConfiguration Standard
    {
        get { return new MonoSQLiteConfiguration(); }
    }

    public MonoSQLiteConfiguration()
    {
        Driver();
        Dialect();
        Raw("query.substitutions", "true=1;false=0");
    }

    public MonoSQLiteConfiguration InMemory()
    {
        Raw("connection.release_mode", "on_close");
        return ConnectionString(c => c
            .Is("Data Source=:memory:;Version=3;New=True;"));

    }

    public MonoSQLiteConfiguration UsingFile(string fileName)
    {
        return ConnectionString(c => c
            .Is(string.Format("Data Source={0};Version=3;New=True;", fileName)));
    }

    public MonoSQLiteConfiguration UsingFileWithPassword(string fileName, string password)
    {
        return ConnectionString(c => c
            .Is(string.Format("Data Source={0};Version=3;New=True;Password={1};", fileName, password)));
    }
}

  

3. 用Nuget添加Mono.Data.Sqlite的引用

 

这样就把IIS+SQLite+Nhibernate的环境移植到Jexus+Sqlite(MONO)+Nhibernate上了.
