流畅的nhibernate配置不工作 [英] fluent nhibernate configuration not working

问题描述

解决：在配置代码时使用ClassMap，在配置文件中配置ClassMapping，但在代码中进行映射。

Solved: ClassMap when configuration in code, ClassMapping when configuration in config file, but mapping in code.

当尝试将Object1类型的对象保存到我的数据库我收到错误：

When trying to save an object of type Object1 to my database I get the error:

不存在：Object1。

No persister for: Object1.

b $ b

类定义：

Class definition:

public class Object1
{
    public virtual Guid Id { get; protected set; }
    public virtual DateTime Created { get; protected set; }
    public virtual DateTime LastModified { get; protected set; }
    public virtual Other Reference { get; set; }
}

映射：

public class Object1Mapping : ClassMapping<Object1>
{
    public Object1Mapping()
    {
        Id(p => p.Id);
        Property(p => p.Created);
        Property(p => p.LastModified);
        ManyToOne(p => p.Reference, m => m.Cascade(Cascade.Remove));
    }
}

配置代码：

sessionFactory = Fluently.Configure()
    .Database(MsSqlConfiguration.MsSql2012
        .ConnectionString(c => c
            .Server("serverUrl")
            .Database("myMsSqlDatabase")
            .Username("sa")
            .Password("pasword1")))
    .Mappings(m => m.FluentMappings
        .AddFromAssemblyOf<Object1Mapping>()
        .AddFromAssemblyOf<Object1>()
   .BuildSessionFactory();

我的所有类都是公共的，我为每个需要持久化的类添加了 AddFromAssemblyOf 添加类本身和映射类我知道一个 AddFromAssembly 应该足够，因为应该从该程序集添加所有的映射类，所有我的映射类都在一个项目中文件夹。

All my classes are public and I added an AddFromAssemblyOf for every class that needs a persister. Also I tried both adding the classes themselves and the mapping classes. I know that one AddFromAssembly should be enough as should add all mapping classes from that assembly and all my mapping classes are in one project in one folder.

我设法运行诊断程序，它通过正确的程序集，但没有发现映射，这是结果：

I managed to run diagnostics and it's looking through the correct Assembly, but it discovered no mappings, here is the result:

流畅的映射

扫描的源：

Fluent Mappings

Sources scanned:

DomainModel.NHibernate，Version = 1.0.0.0，Culture = neutral，
PublicKeyToken = null

Project.DomainModel.NHibernate, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

发现的映射：

未找到

扫描的来源：

未找到

跳过的类型：

未找到

候选类型：

未找到

我读了很多文档和问题，看来我错过了一些很明显的东西：

I've read tons of documentation and questions, it seems I'm missing something really obvious :(

推荐答案

Fluently.Configure 支持所有不同的映射类型（通过代码，流利，自动映射，

All different mapping types (by code, fluent, automapping, xml...) are supported by Fluently.Configure. It just needs different kind of code snippet to add it to your configuration.

这里有一些不同的方式通过流利地添加映射到你的配置 / code>配置

Here are some different ways to add mappings to your configuration via Fluently configuration

.Mappings(m =>
{
    foreach (var assembly in MapAssemblies)
    {
        m.FluentMappings.AddFromAssembly(assembly);
        m.HbmMappings.AddFromAssembly(assembly);
        m.AutoMappings.Add(..)
    }    
})

...

.ExposeConfiguration(cfg => {
    foreach (var assembly in MapAssemblies)
    {
        cfg.AddDeserializedMapping(HbmMappingHelper.GetMappings(assembly), null);
        cfg.AddInputStream(NHibernate.Mapping.Attributes.HbmSerializer.Default.Serialize(
                    System.Reflection.Assembly.GetExecutingAssembly()));
    }

上面使用的助手类：

public class HbmMappingHelper
{
    public static HbmMapping GetMappings(Type[] types)
    {
        ModelMapper mapper = new ModelMapper();

        foreach (var type in types)
        {
            mapper.AddMappings(Assembly.GetAssembly(type).GetExportedTypes());
        }

        return mapper.CompileMappingForAllExplicitlyAddedEntities();
    }

    public static HbmMapping GetMappings(Assembly assembly)
    {
        ModelMapper mapper = new ModelMapper();

        mapper.AddMappings(assembly.GetExportedTypes());

        return mapper.CompileMappingForAllExplicitlyAddedEntities();
    }
}
