我希望有人可以帮助我解决这个问题。我一直在绞尽脑汁
我的大脑和我的项目很快就要到期了。先感谢您。
插入新索引时收到索引超出范围异常
记录。在无休止的搜索信息后，建议
我的映射中的列值的数量与我的不匹配
持久类。然而，我数了又数，他们似乎
匹配。正如您在下面的代码中看到的那样，我正在使用
NHibernate.Mapping.Attributes 来做我的映射。也许我在做
那里有问题。
我终于下载了 NHibernate 源并通过我的调试
问题。下面是 NHibernate 正在尝试的插入语句
build :
{插入 WTSLIB33T.PRODDATA(PSTAT、PCONO、PDVNO、PWKTY、PCRTY、
PTSID、PCNNO、PDTTK、PJBNO、PSJNO、PTKNO、PCWNO、PWKAR、PWKDC、PWKCD、
PCNWO、PWDNO、PDESC、PDCCD、PHRS、PUNIT、PSEQ、PCUST) 值
(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}
可以看到，参数的数量与字段的数量相匹配
在列表中。我还将这个生成的插入与我的类(class)相匹配
我发现 PSEQ 和 PCUST 列乱序了
和我坚持不懈的类(class)。然后，一边调试一边通过 Dehydrate
功能我发现了两个可能的问题。首先是我注意到
对 NullSafeSet 函数的调用将参数 0 设置为我的 PSEQ
字段应设置为但插入语句中的参数 0 是
统计数据。
我注意到的第二个问题是最后一次调用“index +=
ArrayHelper.CountTrue(includeColumns[i]);"在脱水函数中
将索引变量保留为 23，这是正确的；然而，接下来
调用“IdentifierType.NullSafeSet(statement, id, index,
session);"，它检查行 id，传入索引 23
将超出范围。对于基于零的值，该值应为 22
大批。
protected int Dehydrate(object id, object[] fields, object rowId, bool[] includeProperty, bool[][] includeColumns, int table, IDbCommand statement, ISessionImplementor session, int index)
{
if (log.IsDebugEnabled)
{
log.Debug("Dehydrating entity: " + MessageHelper.InfoString(this, id, Factory));
}
// there's a pretty strong coupling between the order of the SQL parameter
// construction and the actual order of the parameter collection.
for (int i = 0; i < entityMetamodel.PropertySpan; i++)
{
if (includeProperty[i] && IsPropertyOfTable(i, table))
{
PropertyTypes[i].NullSafeSet(statement, fields[i], index, includeColumns[i], session);
index += ArrayHelper.CountTrue(includeColumns[i]);
}
if (rowId != null)
{
// TODO H3.2 : support to set the rowId
// TransactionManager.manager.SetObject(ps, index, rowId);
// index += 1;
throw new NotImplementedException("support to set the rowId");
}
else if (id != null)
{
IdentifierType.NullSafeSet(statement, id, index, session);
index += IdentifierColumnSpan;
}
return index;
}

最佳答案
此问题的一个可能原因是您已将两个属性映射到同一列。例如，您已将外键关系映射为关系和属性字段，或者您有一个描述符，您也已将其映射为字段。
查看主键映射，我看到它被映射了两次:
[NHibernate.Mapping.Attributes.CompositeId(1, UnsavedValue=NHibernate.Mapping.Attributes.UnsavedValueType.Undefined)]
[NHibernate.Mapping.Attributes.KeyProperty(2, Name = "PSEQ", Column = "PSEQ", Type="Decimal")]
[NHibernate.Mapping.Attributes.KeyProperty(2, Name = "PCUST", Column = "PCUST")]
//[NHibernate.Mapping.Attributes.Generator(3, Class="none")]
[NHibernate.Mapping.Attributes.Property(4, Name="PSEQ", Column="PSEQ")]
你确定这是用 NHiberante 属性映射复合键的方法吗？我自己没用过。但我的猜测是，正是这一点导致 NHibernate 认为您已将 PSEQ 列映射了两次。
我认为您应该只使用 KeyProperty 并跳过属于主键的属性的 Property 属性。
尝试在类的顶部添加它(不要装饰属性声明)
[CompositeId(1,UnsavedValue=UnsavedValueType.Undefined)]
[KeyProperty(2, Name="PSEQ", Column="PSEQ")]
[KeyProperty(4, Name="PCUST", Column="PCUST")]
