我是 Spring 天的初学者，
我正在尝试从网上下载文件并将其存储在我的本地磁盘中，但我收到了瓷砖中提到的编译错误
我试图使ResponseEntity和json成为它工作的字符串但是当我尝试打开图像时图像被损坏或不受支持
我的代码：
public static void main(String arg[]) throws IOException
{
HttpHeaders requestHeaders = new HttpHeaders();
//requestHeaders.setAcceptEncoding(ContentCodingType.IDENTITY);
HttpEntity<?> requestEntity = new HttpEntity<Object>(requestHeaders);
// Create a new RestTemplate instance
RestTemplate restTemplate = new RestTemplate();
// Add the String message converter
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
// Make the HTTP GET request, marshaling the response to a String
ResponseEntity<byte[]> response = restTemplate.exchange("http://www.nndb.com/people/954/000354889/duke-kahanamoku-2-sized.jpg", HttpMethod.GET, requestEntity,byte[].class);
File file = new File("/Users/crohitk/Desktop/image.jpg");
// if file doesnt exists, then create it
if (!file.exists()) {
file.createNewFile();
}
byte[] json =response.getBody();
FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(json);
bw.close();
System.out.println("Done");
System.out.println(response.getBody());
}

Writer用于写字符 . 使用
OutputStream将字节写入文件 .
