问题：ImageIO.read 无法读取中文路径

String path = "http://127.0.0.1:8080/你过来呀/2023-01-30/533701000000090028/我过来了呀haha.jpg";
URL u=new URL(path);
BufferedImage coverImg = ImageIO.read(u);

上面代码会报下面错误：

解决方案：对路径中文部分路径进行编码

// 对中文路径的中文部分进行编码
public static String encodeChinese(String url) throws UnsupportedEncodingException {
    String resultURL = "";
    //遍历字符串
    for (int i = 0; i < url.length(); i++) {
        char charAt = url.charAt(i);
        //只对汉字处理
        if (isChineseChar(charAt)) {
            String encode = URLEncoder.encode(charAt+"","UTF-8");
            resultURL+=encode;
        }else {
            resultURL+=charAt;
        }
    }
    return resultURL;
}

String coverFilePath = "http://127.0.0.1:8080/你过来呀/2023-01-30/533701000000090028/我过来了呀haha.jpg";
String path = encodeChinese(coverFilePath);
URL u = new URL(path);
BufferedImage coverImg = ImageIO.read(u);
image.createGraphics().drawImage(coverImg, 0, 210, 320, 180, null);
