示例1: CreatePosts
// public void testMapReduce(){//插入测试数据
//Mongo _db = new Mongo( "127.0.0.1" ).getDB( "jmrtest" );
//DBCollection c = _db.getCollection( "jmr" );
// c.drop();
// c.save( new BasicDBObject( "x" , new String[]{ "a" , "b" } ) );
// c.save( new BasicDBObject( "x" , new String[]{ "b" , "c" } ) );
// c.save( new BasicDBObject( "x" , new String[]{ "c" , "d" } ) );
// MapReduceOutput out =
// c.mapReduce( "function(){ " +
// "for( var i=0; i<this.x.length; i++ )" +
// "{ emit(this.x[i] , 1 ); } }",//map函数内使用this来操作当前行表示的对象，并且使用emit(key,value)方法来向reduce提供参数：
// "function(key,values){" +
// " var sum=0; " +
// "for( var i=0; i<values.length; i++ )" +
// " sum += values[i];" +
// " return sum;}" ,//reduce的key就是emit(key,value)的key，value_array是同个key对应的多个value数组：
// "result" , null );//mapReduce 方法2.x以后和1.X不同
// Map<String,Integer> m = new HashMap<String,Integer>();
// for (DBObject element : out.results()) {
// System.out.println(element.get("value"));
// }
// for ( DBObject r : out.results() ){
// System.out.println( ((Number)(r.get( "value" ))).intValue());
// m.put( r.get( "_id" ).toString() , ((Number)(r.get( "value" ))).intValue() );
// }
// System.out.println(m.size());
// assertEquals( 4 , m.size() );
// assertEquals( 1 , m.get( "a" ).intValue() );
// assertEquals( 2 , m.get( "b" ).intValue() );
// assertEquals( 2 , m.get( "c" ).intValue() );
// assertEquals( 1 , m.get( "d" ).intValue() );
//}
