用zxing生成二维码时，错误提示 MatrixToImageWriter refers to the missing type Path

[shurychen]

在用zxing生成二维码时，writertoPath()函数出错，错误提示为：The method writeToPath(BitMatrix, String, Path) from the type MatrixToImageWriter refers to the missing type Path，以下是代码，感觉和网上的代码基本一样的，本人自己看不出错在哪里，
这是为什么呢，哪位大神帮帮忙，不胜感激！！！！！！！！！

package com.chen.zxing;

import java.io.File;
import java.nio.file.Path;
import java.util.HashMap;

import javax.sound.midi.Patch;


import com.google.zxing.BarcodeFormat;
import com.google.zxing.EncodeHintType;
import com.google.zxing.MultiFormatWriter;
import com.google.zxing.WriterException;
import com.google.zxing.client.j2se.MatrixToImageWriter;
import com.google.zxing.common.BitMatrix;
import com.google.zxing.qrcode.decoder.ErrorCorrectionLevel;

public class QR_CreateCode {
public static void main(String[] args) {
int width=300;
int height=300;
String format="png";
String content="www.baidu.com";

HashMap hints=new HashMap();
hints.put(EncodeHintType.CHARACTER_SET, "utf-8");
hints.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.M);
hints.put(EncodeHintType.MARGIN, 2);


try {
BitMatrix bitMatrix=new MultiFormatWriter().encode(content, BarcodeFormat.QR_CODE, width, height,hints);
Path file1=new File("E:/NewJavaWorkpacel/img.png").toPath();

MatrixToImageWriter.writeToPath(bitMatrix, format, file1);

} catch (WriterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }

}
