ASP.NET&Spring.NET&NHibernate最佳实践(四)——第3章人事子系统（1）_[Asp.Net教程]
人事子系统分层结构为：领域模型层（DomainModel）——数据访问层（Dao）——服务层（Sevice）——表示层（Web），在Web页面中采用了ObjectDataSource作为GridView的数据源，并为此增加了一个帮助类。
在数据访问层中充分体现了Spring.NET和NHibernate的无缝集成，只要继承HibernateDaoSupport就能很便捷的使用NHibernate，而不需要很深入了解NHibernate。
3.1. 人事子系统领域模型层(DomainModel)
部门（Dept.cs）
using System;
using System.Collections.Generic;
using System.Text;
namespace Guushuuse.SalaryPrj.HR.DomainModel
{
/**////

public class Dept
{
private int _id;

private string _name;

public virtual int ID
{
get { return _id; }
set { _id = value; }
}
/**////
/// 部门代码
///
public virtual string Code
{
get { return _code; }
set { _code = value; }
}
/**////
/// 部门名称
///
public virtual string Name
{
get { return _name; }

}
#endregion 属性

/**////

}
#endregion 构造函数
}
}
员工（Employee.cs）
using System;
using System.Collections.Generic;
using System.Text;
namespace Guushuuse.SalaryPrj.HR.DomainModel
{
/**////
/// 员工
///
public class Employee
{

/**////

3.2. 人事子系统映射文件(HBM)
Dept.hbm.xml
Employee.hbm.xml
3.3. 人事子系统数据访问层(Dao)
部门数据访问接口（IDeptDao.cs）
using System;
using Guushuuse.SalaryPrj.HR.DomainModel;
using System.Collections;
namespace Guushuuse.SalaryPrj.HR.Dao
{
/**////
/// 部门数据访问接口
///
public interface IDeptDao
{
void CreateDept(Dept dept);
void DeleteDept(Dept dept);
IList GetAllDepts();
Dept GetDept(int deptID);
void UpdateDept(Dept dept);
}
}
部门数据访问类（DeptDao.cs）
using System;
using System.Collections.Generic;
using System.Text;
using Spring.Data.NHibernate.Support;
using Spring.Transaction.Interceptor;
using Guushuuse.SalaryPrj.HR.DomainModel;
using System.Collections;
namespace Guushuuse.SalaryPrj.HR.Dao
{
/**////
/// 部门数据访问类
///
public class DeptDao : HibernateDaoSupport, IDeptDao
{
public DeptDao()
{
}
[Transaction(ReadOnly = false)]
public void CreateDept(Dept dept)
{
HibernateTemplate.Save(dept);
}
[Transaction(ReadOnly = false)]
public void UpdateDept(Dept dept)
{
HibernateTemplate.Update(dept);
}
[Transaction(ReadOnly = false)]
public void DeleteDept(Dept dept)
{
HibernateTemplate.Delete(dept);
}
public IList GetAllDepts()
{
return HibernateTemplate.LoadAll(typeof(Dept));
}
public Dept GetDept(int deptID)
{
return (Dept)HibernateTemplate.Get(typeof(Dept), deptID);
}
}
}
员工数据访问接口（IEmployeeDao.cs）
using System;
using Guushuuse.SalaryPrj.HR.DomainModel;
using System.Collections;
namespace Guushuuse.SalaryPrj.HR.Dao
{
/**////
/// 员工数据访问接口
///
public interface IEmployeeDao
{
void CreateEmployee(Employee employee);
void DeleteEmployee(Employee employee);
IList GetAllEmployees();
Employee GetEmployee(int employeeID);
void UpdateEmployee(Employee employee);
}
}
员工数据访问类（EmployeeDao.cs）
using System;
using System.Collections.Generic;
using System.Text;
using Spring.Data.NHibernate.Support;
using Spring.Transaction.Interceptor;
using Guushuuse.SalaryPrj.HR.DomainModel;
using System.Collections;
namespace Guushuuse.SalaryPrj.HR.Dao
{
/**////
/// 员工数据访问类
///
public class EmployeeDao : HibernateDaoSupport, IEmployeeDao
{
public EmployeeDao()
{
}
[Transaction(ReadOnly = false)]
public void CreateEmployee(Employee employee)
{
HibernateTemplate.Save(employee);
}
[Transaction(ReadOnly = false)]
public void UpdateEmployee(Employee employee)
{
HibernateTemplate.Update(employee);
}
[Transaction(ReadOnly = false)]
public void DeleteEmployee(Employee employee)
{
HibernateTemplate.Delete(employee);
}
public IList GetAllEmployees()
{
return HibernateTemplate.LoadAll(typeof(Employee));
}
public Employee GetEmployee(int employeeID)
{
return (Employee)HibernateTemplate.Get(typeof(Employee), employeeID);
}
}
}
修改Config/Guushuuse.SalaryPrj.HR.config文件，新增object
