Hibernate搜索JBoss 7下的JGroups配置

Question

我是使用Hibernate Search編寫Web應用程序的團隊的一員，我們最近試圖開始實現使用JGroups來保持不同節點上的Lucene索引與彼此。

但是，我一直無法通過獲得此設置的最基本的第一步，文檔似乎quite sparse。

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="myFactory"> 
<property name="dataSource" ref="myDataSource"/> 
<property name="persistenceXmlLocation" value="/WEB-INF/persistence.xml"/> 
<property name="persistenceUnitName" value="persistenceUnit"/> 
<property name="jpaVendorAdapter" ref="vendorAdapter"/> 
<property name="jpaProperties"> 
    <props> 
     <prop key="hibernate.search.worker.backend.jgroups.configurationFile">jgroups-config.xml</prop> 
     <prop key="hibernate.search.default.directory_provider">infinispan</prop> 
     <prop key="hibernate.search.default.indexBase">indexes</prop> 
     <prop key="hibernate.search.default.worker.backend">jgroups</prop> 
     <prop key="hibernate.search.services.jgroups.clusterName">MyCluster</prop> 
     <prop key="hibernate.search.error_handler">log</prop> 
     <prop key="hibernate.search.lucene_version">LUCENE_36</prop> 
     <prop key="hibernate.search.generate_statistics">true</prop> 
     <prop key="hibernate.search.jmx_enabled">true</prop> 
    </props> 
</property> 

這裏的關鍵屬性是hibernate.search.worker.backend.jgroups.configurationFile這給了JGroups的配置文件，這是我們最終需要的名字。我試過把這個文件放在WEB-INF中，並將其放在JBoss模塊目錄結構中的其他文件所在位置併成功加載的道具文件中，但它並沒有被拾取。

在日誌中我可以看到：

我截斷Unable to use any JGroups configuration mechanisms provided in properties屬性的列表，因爲它會佔用幾頁，但如果你看行，你可以看到它列出了財產在同一時間，它說它無法找到它。

所以，它沒有拿起配置文件的位置，它使用的是默認值。

有沒有人在這裏使用Hibernate搜索jgroups？你有沒有設法提供一個自定義的jgroups配置文件？你是怎麼做到的？

Answer 1

沒錯。我不得不下載Hibernate搜索源，並通過服務器啓動來找到它。我使用的是Hibernate 4.2，我指的文檔版本大多是3.2。

在兩個版本之間，有人將該屬性從hibernate.search.worker.backend.jgroups.configurationFile更名爲hibernate.search.services.jgroups.configurationFile。
