Question

我正在尝试创建一个POC应用程序来探索Castle.ActiveRecord但由于某种原因，我得到了＃34;无法编译映射文档：（string）＆＃34;错误信息。这是一个非常基本的代码。我查看了Castle.ActiveRecord的现有文档，但我无法弄清楚这个问题的原因。当然它看起来像某种配置故障。

Program.cs的

class Program
{
    static void Main(string[] args)
    {
        IConfigurationSource source = ConfigurationManager.GetSection("activerecord") as IConfigurationSource;
        ActiveRecordStarter.Initialize(source, typeof(Student));

        var students = Student.FindAll();
        foreach (var student in students)
        {
            Console.WriteLine(student.Name);
        }
    }
}

Student.cs

[ActiveRecord("Student")]
public class Student : ActiveRecordBase<Student>
{
    [PrimaryKey]
    public int Id { get; set; }

    [Property]
    public string Name { get; set; }

    [Property]
    public string Grade { get; set; }
}

的App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="activerecord" type="Castle.ActiveRecord.Framework.Config.ActiveRecordSectionHandler, Castle.ActiveRecord"/>
  </configSections>

  <activerecord isWeb="true">
    <config>
      <add key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
      <add key="hibernate.dialect" value="NHibernate.Dialect.MsSql2000Dialect"/>
      <add key="hibernate.connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
      <add key="hibernate.connection.connection_string" value="Server=localhost;Database=Art_DEV;Trusted_Connection=True;"/>
    </config>
  </activerecord>

  <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
</configuration>

我得到的错误是：

{"Error adding information from class ConsoleApplication1.Student to NHibernate. Check the inner exception for more information"}
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2146233088

    InnerException: {"Could not compile the mapping document: (string)"}

Answer 1

在您的域定义中使您的属性为“虚拟”，它将看起来像这样：

[ActiveRecord("Student")]
public class Student : ActiveRecordBase<Student>
{
    [PrimaryKey]
    public virtual int Id { get; set; }

    [Property]
    public virtual string Name { get; set; }

    [Property]
    public virtual string Grade { get; set; }
}

这是NHibernate为了进行延迟加载所必需的（Active Record基于NHibernate）

在这里查看更多：nhibernate and virtual class properties?

此外，如果它没有帮助，请考虑查找详细消息（通过增强日志级别），因为通常Active Record可以告诉您什么是完全错误

另外，尝试从app.config活动记录配置中删除“hibernate”命名空间

<add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
<add key="dialect" value="NHibernate.Dialect.MsSql2000Dialect"/>
<add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
<add key="connection.connection_string" value="Server=localhost;Database=Art_DEV;Trusted_Connection=True;"/>

检查您正在使用的MSSQL版本，因为您已设置MsSql2000Dialect
