        	CsvReader cr = new CsvReader(in, ',', Charset.forName("GBK"));
			cr.readHeaders();
			String[] headers = cr.getHeaders();
			System.out.println(headers.length);
			if(headers.length != 3){
				System.out.println("错误");
			}
			while(cr.readRecord()){
				System.out.print(cr.get(0));
				System.out.print(cr.get(1));
				System.out.print(cr.get(2));
				System.out.print(cr.get(3));
