nhibernate,无法解析属性QueryOver只有一个表

Question

我发现了十几个与我类似的问题,但没有一个能解决我的问题.

先感谢您

好,

我有这门课

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>

这就是我所说的

 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"}

编辑:

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...

<property name="email" column="emailaddress" />

把它设置为......

<property name="Email" column="emailaddress" />

它的工作原理.现在,这是NHibernate通过字段填充/读取我的属性的保证吗？希望如此.

Answer 1

这应该有帮助：将get和set的设置更改为不同

<hibernate-mapping ... default-access="field.camelcase">

并映射属性：

<property name="Email" column="emailaddress" />

NHibernate 将使用字段来设置，使用属性来获取。此查询结束：

return tx.QueryOver<User>()    
  .Where(u => u.Email == emailAddress)  
  .SingleOrDefault();

...现在可以工作
