Executing MongoDB Stored JavaScript/Procedures from Spring Java

Question

I have few stored Javascripts in mongodb. I am using spring springframework.data.mongodb to access mongodb. How can i execute stored JavaScripts/procedures from this ?

Answer 1

found the solution.

BasicDBObject obj = new BasicDBObject();
obj.append( "$eval" , "stored_javascript_name()" );

CommandResult t=mongoTemplate.executeCommand(obj);
Object obj1=t.get("retval");

Answer 2

BasicDBObject obj = new BasicDBObject();
String menu="湖南卫视";
String program="天路啦：东方不亮西方亮";
obj.append( "$eval" , "keyword_store('"+menu+"','"+program+"')" );

Another thing you should know is adding single quotes when you transfer string parameter.
