java 下载图片问题
public static void main(String[] args)throws
IOException {
String targetImage = "http://www.baidu.com/img/baidu_sylogo1.gif";
URL url = null;
FileOutputStream outfile = null;
InputStream infile = null;
URLConnection con = null;
File file=new File("E:/myeclispeWorkbase/samplev/WebRoot/downloadImg");
System.out.println(file);
byte [] buffer = null;
try{
url = new URL(targetImage);
outfile = new FileOutputStream(file);
con = url.openConnection();
infile = con.getInputStream();
buffer = new byte[1024];
while(infile.read(buffer, 0, 1024) != -1){
outfile.write(buffer);
}
}catch (Exception e) {
e.printStackTrace();
}finally{
infile.close();
outfile.close();
}
}
麻烦帮我看看这段代码有什么问题,为什么一运行就告诉我
E:/myeclispeWorkbase/samplev/WebRoot/downloadImg 访问被拒绝
我的目的很简单 就是要从网络上获取一张图片,然后保存在项目的某个文件夹中
------解决方案--------------------没人回答啊?最近回答下 。原因是:file是个文件夹,文件夹不能有写的功能,应该这样:
File file = new File("/downloadImg/a.jpg");
if (!file.exists()) file.createNewFile(); 如果这个(a.jpg)文件不存在就创建
