流利的nhibernate映射问题

我有两个对象Customer_policy和policy_maturity。流利的nhibernate映射问题

public class Customer_policy 
{ 
    public virtual String policy_no { get; set; } 
    public virtual DateTime maturity_date { get; set; } 
    public virtual Boolean matured_status { get; set; } 
} 

public class Policy_maturity 
{ 
    public virtual string policy_no { get; set; } 
    public virtual string customer_id { get; set; } 
    public virtual float maturity_amt { get; set; } 
    public virtual string policy_type { get; set; } 
    public virtual DateTime pay_date { get; set; } 
}

当客户创建策略Customer_policy正在填充，但Policy_maturity应该保持为空（我已经完成）。当策略成熟时，我想在Policy_maturity中插入一行，并更新相应Customer_policy的matured_status字段。我应该做什么类型的映射，以便只通过一次点击数据库就可以完成插入和更新？感谢您的建议。

您将需要问NHibernate批量两个DML查询。有关如何在NHibernate中使用批处理的详细说明，请参见this blog post。

在交易中包装这两个操作（如博客文章中的示例）也是一个好主意。

一个建议：

public class CustomerPolicy 
{ 
    public virtual String PolicyNumber { get; private set; } 
    public virtual DateTime MaturityDate { get; set; } 
    public virtual PolicyMaturity Maturity { get; private set; } 

    public virtual Boolean HasMatured { get { return Maturity != null; } } 

    public virtual void DoMature(Customer customer, float maturity_amt, string policyType, DateTime payDate) 
    { 
     DoMature(new PolicyMaturity 
     { 
      Customer = customer, 
      MaturityAmt = maturity_amt, 
      PolicyType = policyType, 
      PayDate = payDate, 
     }); 
    } 
    /*public*/ virtual void DoMature(PolicyMaturity maturity) 
    { 
     Maturity = maturity; 
     MaturityDate = DateTime.Today; 
    } 
} 

public class PolicyMaturity 
{ 
    public virtual String PolicyNumber { get; private set; } 
    public virtual CustomerPolicy Policy { get; set; } 
    public virtual Customer Customer { get; set; } 
    public virtual float MaturityAmt { get; set; } 
    public virtual string PolicyType { get; set; } 
    public virtual DateTime PayDate { get; set; } 
} 

class CustomerPolicyMap : ClassMap<CustomerPolicy> 
{ 
    public CustomerPolicyMap() 
    { 
     Id(cp => cp.PolicyNumber).GeneratedBy.Assigned(); 

     Map(cp => cp.MaturityDate); 
     HasOne(cp => cp.Maturity); 
    } 
} 

class PolicyMaturityMap : ClassMap<PolicyMaturity> 
{ 
    public PolicyMaturityMap() 
    { 
     Id(cp => cp.PolicyNumber).GeneratedBy.Foreign("Policy"); 

     HasOne(cp => cp.Policy); 

     References(cp => cp.Customer); 
     Map(cp => cp.MaturityAmt); 
     Map(cp => cp.PayDate); 
     Map(cp => cp.PolicyType); 
    } 
}

然后如果你保存更新NHibernate的Customerpolicy应该批两个更新
