我將通過GlassFish服務器運行的JavaEE JSF應用程序從使用受管Bean遷移到使用CDI。Neo4j org.apache.lucene.store.LockObtainFailedException：在CDI遷移後鎖定獲取超時
一切正常，所有的網頁正常顯示，除了它使用的Neo4j現在返回
org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out
我追這個問題到特定git的承諾，我被改變我的類庫控制器的頁面：
@ManagedBean
@SessionScoped
public class LibraryController
{
private GraphStorage graphStorage;
public LibraryController()
{
graphStorage = new GraphStorage();
graphStorage.setUp();
}
}
到
@Named
@SessionScoped
public class LibraryController
{
private GraphStorage graphStorage;
public LibraryController()
{
graphStorage = new GraphStorage();
graphStorage.setUp();
}
}
超時錯誤公頃ppens當Neo4j的變化與tx.finish致力於GraphStorage的設置（）方法中：
public class GraphStorage
{
private void createNodespace()
{
Transaction tx = graphDb.beginTx();
try
{
Node rootNode = graphDb.createNode();
setGraphRootUUIDString(java.util.UUID.randomUUID().toString());
rootNode.setProperty("uuid", getGraphRootUUIDString());
index.add(rootNode, "uuid", rootNode.getProperty("uuid"));
tx.success();
}
finally
{
tx.finish();
}
}
public void setUp()
{
graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(FILESYSTEM_DB);
indexManager = graphDb.index();
index = indexManager.forNodes("indexNodes");
registerShutdownHook();
createNodespace();
}
}
通知我有內部GraphStorage主要方法，它調用相同的設置（），並且創建了運行良好的同一節點，似乎CDI以某種方式打破了Neo4j的工作方式。 任何提示如何解決此問題？
編輯： 好發現，裏面GraphStorage的主要方法正確地工作，因爲它會調用構造函數一次，而JavaEE的CDI調用GraphStorage多次 因顯然是CDI是如何實現（即代理人）構造函數。仍然不」知道如何解決這個

燦你分享完整的堆棧跟蹤？ –
添加了跟蹤日誌，實際上我已經將錯誤追溯到JavaEE 7 CDI，它調用了三次GraphStorage類的構造函數，因此調用了setUp（）。不知道如何修改CDI行爲或是否應該接受它並解決neo4j錯誤。 – dendini
