LIE 从 Hibernate Search 提交
LIE on commit from Hibernate Search
我们正在将 Hibernate Search 3.4 添加到我们现有的 Web 应用程序中（使用 Hibernate 3.6 和 Spring 3.2.3）。默认
<prop key="hibernate.search.lucene_version">LUCENE_31</prop>
<prop key="hibernate.search.default.directory_provider">filesystem</prop>
<prop key="hibernate.search.default.indexBase">C:\scratch\lucene</prop>
<prop key="hibernate.search.Rules.directory_provider">ram</prop>
<prop key="hibernate.search.indexing_strategy">event</prop>
我们在提交交易时遇到了很多谎言。堆栈跟踪将类似于：

VendorController 将保存先前使用预加载模式加载的供应商对象。 类 看起来像这样：
@Indexed
public class VendorModel {
@DocumentId
protected int id;
@ContainedIn
protected Set<CreditorPaymentModel> payments = new HashSet<CreditorPaymentModel>(0);
..
}
@Indexed
public class CreditorPaymentModel {
@DocumentId
private int id;
@IndexedEmbedded
private BranchModel branch;
@IndexedEmbedded
private VendorModel paymentpartner;
..
}
@Indexed
public class BranchModel {
@DocumentId
protected int id;
..
}
预加载将加载供应商以及付款集合。在付款收集中，分支未预加载。在保存时（即在提交事务边界上），我们观察到 Hibernate Search 在尝试取消代理 payment.branch 时遇到 LIE。
在 "event" 索引策略的情况下，是否需要正确加载整个对象树（文档生成器树）？或者，换句话说，我们是否需要预加载对象只是为了 Hibernate Search 能够构建文档以传递给索引器？还有其他方法吗？
（我们明确不想使用 OpenSessionInView 解决方案）
谢谢
西蒙
In case of an "event" indexing strategy, does the entire object tree
(document builder tree) need to be properly loaded? Or, in other
words, do we need to preload objects for the sole purpose of Hibernate
Search being able to build a document to pass to the indexer? Are
there other approaches?
在构建 Lucene 文档时，Hibernate Search 必须能够访问需要索引的所有实体的状态。数据要么是急切加载的，要么是延迟加载的，搜索必须能够取消代理它。在后一种情况下，搜索需要首先加载实体的会话。
We explicitly do NOT want to use an OpenSessionInView solution
我个人认为这是最简单的解决方案。您选择反对它的任何原因。但是，如果您真的不想使用这种模式，则需要一直热切地加载数据，或者可以考虑使用 fetch profiles。在后一种情况下，您将需要确保在建立索引时执行正确的提取配置文件。
