nhibernate，仅一个表无法解析属性QueryOver [英] nhibernate, could not resolve property QueryOver only one table
问题描述
我发现了十二个与我的问题类似的问题，但是没有一个问题可以解决我的问题.
I have found a dozen of question similar to mine but none of them offered a solution to my problem.
提前谢谢
好吧
我有这堂课
public class User : IEntity
{
private int id;
public virtual int Id { get { return id; } }
private string email;
public virtual string Email
{
get { return email; }
//private set { email = value; }
}
private string password;
public virtual string Password
{
get { return password; }
//private set { password = value; }
}
private bool isActive;
public virtual bool IsActive
{
get { return isActive; }
//private set { isActive = value; }
}
private bool isRegistered;
public virtual bool IsRegistered
{
get { return isRegistered; }
//private set { isRegistered = value; }
}
private bool hasRequestedApplication;
public virtual bool HasRequestedApplication
{
get { return hasRequestedApplication; }
//private set { hasRequestedApplication = value; }
}
private ContactInfo contactInformation;
public virtual ContactInfo ContactInformation
{
get { return contactInformation; }
//private set { contactInformation = value; }
}
public User(string email)
{
this.email = email;
}
public User(string email, string password):this(email)
{
this.password = password;
}
public User()
{ }
}
这是映射....
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Domain"
namespace="Domain.User" default-access="field">
<class name="User" table="[User]">
<id name="id" column="UserID">
<generator class="identity" />
</id>
<property name="email" column="Email" not-null="true"></property>
<property name="password" column="HashedPassword" not-null="false"></property>
<property name="isRegistered" column="IsRegistered" not-null="true"></property>
<property name="isActive" column="IsActive" not-null="true"></property>
<property name="hasRequestedApplication" column="HasRequestedApplication" not-null="true"></property>
<one-to-one name="contactInformation" class="Domain.User.ContactInfo"/>
</class>
</hibernate-mapping>
这就是我的称呼方式
public class UserRepository: IUserRepository
{
Func<ISession> session;
public UserRepository(Func<ISession> _session)
{
session = _session;
}
[Transaction]
public User FindByEmail(string emailAddress)
{
using (var tx = session())
{
return tx.QueryOver<User>().Where(u => u.Email == emailAddress).SingleOrDefault();
}
}
}
错误... {无法解析属性:电子邮件:Domain.User.User"}
Error... {"could not resolve property: Email of: Domain.User.User"}

好.在某种程度上解决了.我在映射中将所有属性和组件名称更改为大写. 代替...
OK. Solved to some extent. I changed all my properties and components name to capital in my mapping. Instead of...
<property name="email" column="emailaddress" />
将其设置为...
<property name="Email" column="emailaddress" />
，并且有效.现在，是否可以保证NHibernate通过字段填充/读取我的属性?但愿如此.
and it works. Now, is that a guarantee that NHibernate is populating/reading my properties via the fields? I hope so.
推荐答案
这应该有所帮助:将 get 和 set
This should help: Change the settings to be different for get and set
<hibernate-mapping ... default-access="field.camelcase">
并映射属性:
<property name="Email" column="emailaddress" />
NHibernate将使用set作为字段，使用Property作为get字段.此QueryOver:
NHibernate will use field for set and the Property for get. This QueryOver:
return tx.QueryOver<User>()
.Where(u => u.Email == emailAddress)
.SingleOrDefault();
...现在可以使用
这篇关于nhibernate，仅一个表无法解析属性QueryOver的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
