Question

嗯，我现在已经和它斗争了一段时间，我似乎无法找到解决方案，它应该非常简单。我有一个类（非常简单的类）我得到了hbm.xml（SET AS EMBEDDED RESOURCE）我得到了为SQLite设置的配置文件，但我仍然得到[类]未映射。

以下是错误出现的地方，当我运行时：

 Public Sub LoadCentersFromDatabase()
        Try
            Dim session As ISession = OpenSession()
            Dim query As IQuery = session.CreateQuery("from Center")
            Dim foundCenters As IList(Of Center) = query.List(Of Center)()
            MsgBox(foundCenters.Count)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

我的中心课程内的代码

Public Class Center


#Region " Class Constructors "

    Protected Sub New()

    End Sub

    Public Sub New(ByVal centerName As String, ByVal address As String, ByVal city As String, ByVal state As String, ByVal zip As String, ByVal country As String, ByVal phone As String)
        Me.Id = 0
        Me.ExternalId = -1
        Me.CenterName = centerName
        Me.Address = address
        Me.City = city
        Me.State = state
        Me.ZIP = zip
        Me.Country = country
        Me.Phone = phone
    End Sub

    Public Sub New(ByVal id As Integer, ByVal centerName As String, ByVal address As String, ByVal city As String, ByVal state As String, ByVal zip As String, ByVal country As String, ByVal phone As String)
        Me.New(centerName, address, city, state, zip, country, phone)
        Me.Id = id
    End Sub

#End Region

#Region " Declared Auto Properties "

    Public Property Id As Integer
    Public Property ExternalId As String
    Public Property CenterName As String
    Public Property Address As String
    Public Property City As String
    Public Property State As String
    Public Property ZIP As String
    Public Property Country As String
    Public Property Phone As String

#End Region


End Class

这是hbm.xml的代码

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
  <class name="KC.Domain.Center, KC" table="Centers" lazy="true">
    <id name="Id" column="CenterId">
      <generator class="native" />
    </id>
    <property name="CenterName" unique="true" />
    <property name="ExternalId" />
    <property name="Address" />
    <property name="City" />
    <property name="State" />
    <property name="ZIP" />
    <property name="Country" />
    <property name="Phone" />
  </class>
</hibernate-mapping>

App.Config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
  <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
</configSections>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
  <session-factory>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="connection.driver_class">NHibernate.Driver.SQLite20Driver, NHibernate</property>
    <property name="connection.connection_string">
      Data Source=C:\Users\Public\Documents\cats.db;Version=3
    </property>
    <property name="dialect">NHibernate.Dialect.SQLiteDialect</property>
    <property name="query.substitutions">true=1;false=0</property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
    <mapping assembly="KC.Domain"/>
  </session-factory>
</hibernate-configuration>
</configuration>

根据您的映射文件，Center类存在于KC程序集中。根据您的配置，程序集名为KC.Domain。验证包含Center类的程序集的名称。您的映射类可能需要说：

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
    <class name="KC.Domain.Center, KC.Domain" table="Centers" lazy="true">

您可能还想在hbm.xml文件中使用以下内容...

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
                   namespace="KC.Domain"
                   assembly="KC.Domain">
    <class name="Center" table="Centers" lazy="true">

请注意命名空间和程序集声明。我发现让它们在顶部清理我的hbm.xml文件。然后你可以在整个过程中使用相对名称。

nHibernate＆amp; SQLite = [Class]未映射
