String imageUrl;// 使用WebClient下载图片WebClient webClient = WebClientUtil.getWebClient();Mono<ByteArrayOutputStream> byteArrayOutputStreamMono = webClient.get().uri(imageUrl).retrieve().bodyToFlux(DataBuffer.class) // 获取图片内容的DataBuffer流.reduce(new ByteArrayOutputStream(), (baos, dataBuffer) -> {try {Channels.newChannel(baos).write(dataBuffer.asByteBuffer().asReadOnlyBuffer());} catch (IOException e) {throw new RuntimeException("Error writing to ByteArrayOutputStream", e);}return baos;});

使用这段代码时，如果imageUrl中包含%，则它会被自动转为%25，导致404 Not Found错误，怎么办?

一开始用URLEncoder.encode(imageUrl, StandardCharsets.UTF_8);之类的方法，达不到预期

URI uriObj = URI.create(url);即可
