NHibernate 的 SetResultTransformer 方法在Oracle下会出现“Could not find a setter for property”错误,这是Nhibernate在Oracle下使用的一个Bug。针对此Bug我可以自己进行修复。
下载NHibernate源码,将Property下的“ChainedPropertyAccessor.cs”稍作修改就会修复此Bug,代码如下:
using System;
namespace NHibernate.Properties
{
using System.Text.RegularExpressions;
[Serializable]
public class ChainedPropertyAccessor : IPropertyAccessor
{
private readonly IPropertyAccessor[] chain;
public ChainedPropertyAccessor(IPropertyAccessor[] chain)
{
this.chain = chain;
}
#region IPropertyAccessor Members
public IGetter GetGetter(System.Type theClass, string propertyName)
{
for (int i = 0; i < chain.Length; i++)
{
IPropertyAccessor candidate = chain[i];
try
{
return candidate.GetGetter(theClass, propertyName);
}
catch (PropertyNotFoundException)
{
// ignore
}
}
throw new PropertyNotFoundException(theClass, propertyName, "getter");
}
public ISetter GetSetter(System.Type theClass, string propertyName)
{
for (int i = 0; i < chain.Length; i++)
{
IPropertyAccessor candidate = chain[i];
try
{
return candidate.GetSetter(theClass, ToModelName(propertyName));
}
catch (PropertyNotFoundException)
{
//
}
}
throw new PropertyNotFoundException(theClass, propertyName, "setter");
}
public bool CanAccessThroughReflectionOptimizer
{
get { return false; }
}
#endregion
private static string ToModelName(string str)
{
str = str.ToLower();
var temp = Regex.Replace(str, @"_[a-z]?",m=>m.ToString().Substring(1).ToUpper());
var result = Regex.Replace(temp, @"^[a-z]?", m => m.ToString().ToUpper());
return result;
}
}
}
