set properties 'java.util.Date' scala.MatchError #344

Open SeaofRoses opened 4 years ago

SeaofRoses commented 4 years ago

I try to insert a map like this 

String addSql="create (n :Person) SET n += $properties return n";
Map<String, Object> properties=new HashMap<String, Object>();
properties.put("date",new Date());
Map<String, Object> map=new HashMap<String, Object>();
map.put("properties",propertiesMap);
CypherResultSet resultSet = cypherGremlinClient.submit(addSql,map);
List<Map<String, Object>> list = resultSet.all();

however 'java.util.Date' type cannot be inserted

I found that 'Java. Util. Date' was not processed in NodeUtils.toLiteral()
