ich Sätze in meiner Funktion als:

JSONArray arrayNodesOut = new JSONArray(); 

JSONParser parse = new JSONParser(); 
Object obj = parse.parse(node.getProperty("geojson").toString()); 
arrayNodesOut.add(obj); 

hat jemand eine Lösung für das Problem ...

Vielen Dank!

Answer 1

Ihr Plugin ist erfüllt fein, so dass es bedeutet, dass Sie diese Abhängigkeit

<dependency> 
    <groupId>org.json</groupId> 
    <artifactId>json</artifactId> 
    <version>20160212</version> 
</dependency> 

haben Aber wenn man das Plugin einsetzen, es wirft ClassNotFoundException. Es bedeutet, dass json jar nicht auf dem Neo4j-Klassenpfad ist. Fügen Sie entweder json.jar dem Pfad der Neo4j-Klasse hinzu oder erstellen Sie "fat jar" für Ihr Plugin. Siehe here oder here wie.

Answer 2

Ich habe den Fehler gefunden.

Nur ich enthalten de Bibliothek Gläser in Neo4j Lib-Verzeichnis.
