Spring How to insert a raw JSON directly into mongo db without Parsing

Question

I want to insert the JSON string directly into mongo db, without parsing

String json = "{ 'name' : 'Vince' , " +
                "'website' : 'howtodoinjava.com' , " +
                "'address' : { 'addressLine1' : 'Some address' , " +
                              "'addressLine2' : 'Cardiff CF116LW' , " 
                              "'addressLine3' : 'Cardiff, UK'} }"

DBObject dbObject = (DBObject)JSON.parse(json);

collection.insert(dbObject);

In the above example i don't want to use this line

DBObject dbObject = (DBObject)JSON.parse(json);

Is there any out of the box solution for the same ?

Answer 1

The insert method takes one or more DBObject as parameters, so no you cannot pass a String instead.

There are a few ways to obtain a DBObject ;

• Provide a string and parse it (as you did)
• Instantiate a BasicDBObject with empy construtctor and use the put method for each field ( BasicDBObject inherits from HashMap )
• Use the BasicDBObjectBuilder utility
• Provide a Map and use the BasicDBObject constructor that takes a Map
