NHibernate 使用流畅 API 进行配置

1、 创建一个 Configuration

?

1 2 3 4 5 6 7 8 9 10

using Nhibernate.cfg;   var config = new Configuration() .SetProperty("connection.provider", "NHibernate.Connection.DriverConnectionProvider") .SetProperty("connection.driver_class", "NHibernate.Driver.SqlClientDriver") .SetProperty("dialect", "NHibernate.Dialect.MsSql2005Dialect") .SetProperty("proxyfactory.factory_class", "NHibernate.Bytecode.DefaultProxyFactoryFactory, NHibernate") .SetProperty("format_sql", "true") .SetProperty("show_sql", "true") .SetProperty("connection.connection_string", connectionString);

2、 添加映射

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

using NHibernate.Mapping.ByCode;   var mapper = new ModelMapper(); mapper.Class<category>(cm => {    cm.Schema("dbo");    cm.Table("Categories");    cm.Id(cat => cat.CategoryID, map => {       map.Column("CategoryID");       map.Generator(Generators.Native);    });    cm.Property(cat => cat.CategoryName, map => {       map.Column("CategoryName");       map.Length(100);    });    cm.Property(cat => cat.Description, map => {       map.Column("Description");       map.Length(200);    }); });</category>

3、 添加映射至 Configuration

?

1 2	var mappingDocument = mapper.CompileMappingForAllExplicitlyAddedEntities(); config.AddMapping(mappingDocument);
