私のローカル neo4j db パスは C:\neo4j-community-1.9.3_bup です
neo4j DB に接続していくつかのノードを挿入するための単純な Java プログラムを作成しました。
しかし、Neo4jDataBrower を介してこれらのノードを取得しようとしているときに挿入した後、これらはリストされません。
私が使用したコードは、neo4j ポータル自体から取得したものです。
String DB_PATH = "C\\neo4j-community-1.9.3_bup";
Map<String, String> config = new HashMap<String, String>();
config.put( "neostore.nodestore.db.mapped_memory", "10M" );
config.put( "string_block_size", "60" );
config.put( "array_block_size", "300" );
graphDb = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(DB_PATH).setConfig(config).newGraphDatabase();
registerShutdownHook( graphDb );
Transaction tx = graphDb.beginTx();
try
{
firstNode = graphDb.createNode();
firstNode.setProperty( "message", "Hello, " );
secondNode = graphDb.createNode();
secondNode.setProperty( "message", "World!" );
relationship = firstNode.createRelationshipTo( secondNode, RelTypes.KNOWS );
relationship.setProperty( "message", "brave Neo4j " );
tx.success();
}
finally
{
tx.finish();
}
なぜ機能しないのですか？
私に提案してください..私が与えた問題のあるvthパスまたは問題のあるvthコードはありますか?
こんにちは。
