NHiberbate使用

之前一直在用EF进行开发，现在项目需要使用Nhibernate,其实也不需要自己去配置，框架都配置好了的，但是自己还是想要尝试着去配置下

1.下载必要的dll文件（我直接从原来的项目中拷贝的）

这个就够了

2.Nihibernate的配置

<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
      <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
      <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
      <property name="connection.driver_class">
        NHibernate.Driver.SqlClientDriver
      </property>
      <property name="connection.connection_string">Data Source=192.168.2.87;Initial Catalog=db_database1;Persist Security Info=True;User ID=sa;Password=1qaz2wsx~;Connect Timeout=1440;MultipleActiveResultSets=true</property>
      <!--设置sql语句执行的超时时间 1200s-->
      <property name="command_timeout">1200</property>
      <mapping assembly="MvcApplication1.Entity" />
    </session-factory>
  </hibernate-configuration>

3.数据库表->实体类

[Serializable]
    public class People
    {
        public virtual int id { get; set; }
        public virtual string name { get; set; }
        public virtual string sex { get; set; }
        public virtual int age { get; set; }
    }

4.hbm.xml文件的配置

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping assembly="MvcApplication1.Entity" namespace="MvcApplication1.Entity" xmlns="urn:nhibernate-mapping-2.2">
  <class name="People" table="people">
    <id name="id" type="int" unsaved-value="null" >
      <column name="id" length="4" sql-type="int" not-null="true" unique="true"  index="PK__people__3213E83FB00D67C7"></column>
      <generator class="native" >
      </generator>
    </id>
    <property name="name" type="String" >
      <column name="name" length="50" sql-type="varchar" not-null="false" />
    </property>
    <property name="sex" type="String">
      <column name="sex" length="50" sql-type="varchar" not-null="false"></column>
    </property>
    <property name="age" type="int">
      <column name="age" length="4" sql-type="int" not-null="false"></column>
    </property>
  </class>
</hibernate-mapping>

注意将该文件的属性修改下：

否则报找不到文件

到此配置结束，下面是使用的小例子

//using NHibernate.Cfg;
            Configuration cfg = new Configuration();
            cfg.Configure();
            ISessionFactory factory = cfg.BuildSessionFactory();
            ISession session = factory.OpenSession();
            using (ITransaction tran = session.BeginTransaction())
            {
                List<People> result = session.CreateQuery("from People").List<People>().ToList();
                People people = new People
                {
                    id=1,
                    name = "LiLy",
                    sex = "女",
                    age = 23
                };
                session.Save(people);
            }
