的Lucene索引適用於Windows，Linux上的

Question

失敗，我有碼頭9.2上運行的Java應用程序。兩者都使用相同版本的Jetty。索引器在部署後首次運行應用程序。我在Netbeans的Windows 10開發箱中沒有遇到任何問題。當我把它放在一臺linux機器上時，它不工作，我只有SSH訪問權和有限權限。

Java代碼，類人首先運行，類組織運行第二。無論是在同一個Hibernate Session

public static void reindexViaMassIndexer(Class<?> type, SessionFactory factory) { 
    Session session = factory.getCurrentSession(); 
    FullTextSession fullTextSession = Search.getFullTextSession(session); 
    MassIndexerProgressMonitor monitor = new SimpleIndexingProgressMonitor(); 

    try { 
     fullTextSession 
       .createIndexer(type) 
       .typesToIndexInParallel(1) 
       .batchSizeToLoadObjects(BATCH_SIZE) 
       .cacheMode(CacheMode.NORMAL) 
       .threadsToLoadObjects(10) 
       .idFetchSize(BATCH_SIZE) 
       .progressMonitor(monitor) 
       .startAndWait(); 
    } catch (InterruptedException ex) { 
     Logger.getLogger(HibernateLuceneIndexer.class.getName()).log(Level.SEVERE, null, ex); 
    } 

}

還需要什麼嗎？

Answer 1

一個可能的解釋是，你是爲相同的配置創建多個SessionFactories/EntityManagerFactories，從而實例Hibernate Search的多次和創建的索引文件鎖衝突。如果是這樣，那麼不要。也Hibernate search: persist causes sometimes OverlappingFileLockException

看到另外一個可能的解釋：這個版本的Hibernate搜索的是真的老了。您可能遇到自此以後解決的錯誤。我知道有幾個與鎖已經解決的錯誤有關，例如這個：https://stackoverflow.com/a/46284827/6692043
