found the solution.

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

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

If the store procedure has parameters?

I found that if we wanna add parameter, we can do like this: int id = 12; BasicDBObject obj = new BasicDBObject(); obj.append( "$eval" , "stored_javascript_name("+ id +")" ); CommandResult t=mongoTemplate.executeCommand(obj); Object obj1=t.get("retval");

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.
