Hi,
ich habe mein Bastelprojekt von dem einen PC auf den anderen kopiert. Dieses Projekt ist ein Maven multi module Projekt.
Auf dem einen PC funktioniert es ohne Probleme, auf dem ich das Projekt kopiert habe, leider nicht.
Der Fehler tritt, auf wen ich in dem Child maven Projekt die DB schließe. Ich habe keine Probleme beim Öffnen und Suchen, nur das Schließen der DB mach Probleme.
Die Exception löst die folgende Funktion aus. managementService.shutdown(). Folgend die Funktion. Diese sucht in der DB nach Termen.
Ich hoffe jemand kann mir bei der Suche des Fehlers weiterhelfen.
Function
[CODE=java]public String is_Node_in_DB(String node) {
boolean nodeexists = true;
int retcnt = 0;
Node n1 = null;
String db_path = System.getProperty("user.dir") + "./DB_Neo4j/DB_Neo4j/cooccsdatabase";
java.nio.file.Path path = Paths.get(db_path);
if(Files.exists(path))
{
File database = new File(db_path);
managementService = new DatabaseManagementServiceBuilder(database).build();
graphDB = managementService.database(DEFAULT_DATABASE_NAME);
System.out.println("database opened for querying");
try (Transaction tx2 = graphDB.beginTx()) {
do {
n1 = tx2.findNode(Labels.SINGLE_NODE, "name", node);
if(n1 != null)
{// if node found break bevor improvements starts
break;
}
else if(retcnt ==2)
{
node = node.toUpperCase();
}
else if((retcnt == 2)&&(n1 == null))
{
break;
}
else if(Character.isUpperCase(node.charAt(0)))
{ // check of typo lower letter improvements
node = node.substring(0,1).toLowerCase() + node.substring(1);
retcnt = retcnt+1;
}
else if(Character.isLowerCase(node.charAt(0)))
{ // check of typo upper letter improvements
node = node.substring(0,1).toUpperCase() + node.substring(1);
retcnt = retcnt+1;
}
}while(n1 == null);
tx2.commit(); // success();
}
managementService.shutdown();
}
else
{
node = "";
}
return node;
}
