java下载图片到本地，例如从网上下载图片，下载淘宝图片，下载百度图片。

直接上代码如下：

public static void download(String url,String saveFileName) throws Exception{
    URL url1 = new URL(url);
    URLConnection uc = url1.openConnection();
    InputStream inputStream = null;
    FileOutputStream out = null;
    try {
        inputStream = uc.getInputStream();
        out = new FileOutputStream(saveFileName);
        int j = 0;
        while ((j = inputStream.read()) != -1) {
            out.write(j);
        }
    }catch (Exception e){
        e.printStackTrace();
    }finally {
        if(out!=null){
            out.close();
        }
        if(inputStream!=null) {
            inputStream.close();
        }
    }
}

main方法为：

public static void  main(String[] args){
    download("https://hbimg.huabanimg.com/38d7f27f25bc27342ec40ebc1337d074a244b59822f4b-f0S0oF_fw658", "D:\p\1\data\1_无_"+ UUID.randomUUID().toString()+".jpg");
}
