當我試圖從筆記本電腦上傳文件到我的服務器時遇到了一個錯誤。是否可以在桌面上使用RestTemplate而不是Android？
Exception in thread "main" java.lang.NoClassDefFoundError: android/os/Build$VERSION
我搜索了錯誤代碼，發現答案是暗示我應該在Android設備上運行我的代碼，但如果我在我的筆記本上運行我的代碼。是否可以創建在桌面上運行的RestTemplate獨立程序？
服務器端代碼：
@RequestMapping(value="/upload", method=RequestMethod.POST)
public String handleUpload(String filename, MultipartFile file) throws IOException {
if(!file.isEmpty()) {
File saveFile = new File(rootPath + "\\" + filename);
saveFile.createNewFile();
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(new FileOutputStream(saveFile));
FileCopyUtils.copy(file.getInputStream(), bufferedOutputStream);
bufferedOutputStream.close();
return "uploaded successfully";
} else {
return "failed";
}
}
客戶端代碼：
public static void main(String[] args)
{
String url = UPLOAD_URL;
String filePath = PATH + "\\204375-106.jpg";
SimpleClientHttpRequestFactory httpRequestFactory = new SimpleClientHttpRequestFactory();
RestTemplate rest = new RestTemplate(httpRequestFactory);
FileSystemResource resource = new FileSystemResource(new File(filePath));
MultiValueMap<String, Object> param = new LinkedMultiValueMap<String, Object>();
param.add("file", resource);
param.add("filename", "204375-106.jpg");
String string = rest.postForObject(url, param, String.class);
System.out.println(string);
}
