java - Hibernate-Search 与许多 (90) 个实体类挂起。

Question

我正在为我的应用程序使用 hibernate 搜索。它配置良好并且运行完美，直到一段时间后突然停止工作。根据我的说法，原因是我的模型(bean)类的数量。在构建 Hibernate 配置时，我将大约 90 个类添加到我的配置中。

当我禁用 hibernate 搜索(删除搜索注释并使用 Configuration 而不是 AnnotationsConfiguration)时，我尝试启动我的应用程序，它工作正常。

但是，当我启用搜索时，同一个应用程序就挂断了。我尝试调试并找到了它挂起的确切位置。

将所有类添加到我的 AnnotationsConfiguration 对象后，当我说 cfg.buildSessionfactory() 时，它永远不会出现在那个声明中。 (我已经等了几个小时!!!)

此外，当我减少我的模型类的数量(比如减半，即 50)时，它会从该语句中出来并且应用程序工作正常..

谁能告诉我为什么会这样？？我的 hibernate 版本是: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar

此外，如果需要避免使用 AnnotationsConfiguration，我读到我需要明确配置搜索事件监听器。任何人都可以列出所有必要的监听器及其各自的类吗？ (我尝试了 Hibernate Search 书中给出的标准，但它们给了我 ClassNotFound 异常，我在类路径中拥有所有 neccesarty 库)

这是我设法提取的最后几行 hibernate 跟踪:

Donno 最后一行表示什么？？？ (hibernaterecognized......)在最后一行之后它没有做任何事情(也没有踪迹)并且只是挂起....

Answer 1

您需要向我们提供更多信息。你能拍一个thread dump吗并显示日志的最后几行？

有可能是: - 你的实体之一提出问题 - 一些锁或文件挂起(您使用的是哪个操作系统？一些限制并行打开的文件数量)

后面的，如果在linux或者unix上，你可以试试玩玩

ulimit -n <number>

还要确保不时运行索引优化器(查看 Hibernate Search 引用文档)。
