我正在加密一个巨大的数据文件，并且需要将相同的数据传递给我的'inserData'方法，但是当我将加密的数据（user.getEiddata（））传递给inserData方法时，我得到的是“ HTTP状态500-请求处理失败；嵌套异常是java.lang.IllegalArgumentException：[]不是十六进制数字”
转发请求时，需要使用什么正确的数据类型？
请找到我下面的代码：
CryptoUtilsController.java:
-----------------------------
@Controller
@RequestMapping("/")
public class CryptoUtilsController {
@Autowired
UserService userService;
@RequestMapping(method = RequestMethod.GET)
public String encryptData(ModelMap model) {
String key = "John has one cat";
File inputFile = new File("D:\\Other_Project_Codebase\\EncryptionDemo\\document.json");
File encryptedFile = new File("D:\\Other_Project_Codebase\\EncryptionDemo\\document.encrypted");
User user = null;
try {
CryptoUtils cryptoUtils = new CryptoUtils();
user = cryptoUtils.encrypt(key, inputFile, encryptedFile);
System.out.println("eiddata:: "+user.getEiddata());
System.out.println("randomkey:: "+user.getRandomkey());
} catch (CryptoException ex) {
System.out.println("Exception in encryptData");
System.out.println(ex.getMessage());
ex.printStackTrace();
}
return "forward:/insert?eiddata="+user.getEiddata()+"&randomkey="+user.getRandomkey();
}
@RequestMapping("/insert")
public String inserData(@RequestParam String eiddata, @RequestParam String randomkey) {
User user = new User();
user.setEiddata(eiddata);
user.setRandomkey(randomkey);
if (user != null) {
userService.insertData(user);
}
return "hello";
}
}
CryptoUtils.java：
public class CryptoUtils {
private static final String ALGORITHM = "AES";
private static final String TRANSFORMATION = "AES";
public User encrypt(String key, File inputFile, File outputFile)
throws CryptoException {
User user = doCrypto(Cipher.ENCRYPT_MODE, key, inputFile, outputFile);
return user;
}
private User doCrypto(int cipherMode, String key, File inputFile,
File outputFile) throws CryptoException {
try {
Key secretKey = new SecretKeySpec(key.getBytes(), ALGORITHM);
Cipher cipher = Cipher.getInstance(TRANSFORMATION);
cipher.init(cipherMode, secretKey);
FileInputStream inputStream = new FileInputStream(inputFile);
byte[] inputBytes = new byte[(int) inputFile.length()];
inputStream.read(inputBytes);
byte[] outputBytes = cipher.doFinal(inputBytes);
FileOutputStream outputStream = new FileOutputStream(outputFile);
outputStream.write(outputBytes);
//Added
String eidData = null;
String randomKey = null;
User user = new User();
try{
DataInputStream dis = new DataInputStream (new FileInputStream (outputFile));
byte[] datainBytes = new byte[dis.available()];
dis.readFully(datainBytes);
dis.close();
eidData = new String(datainBytes, 0, datainBytes.length);
randomKey = UUID.randomUUID().toString();
user.setEiddata(eidData);
user.setRandomkey(randomKey);
}catch(Exception ex){
ex.printStackTrace();
}
//End
inputStream.close();
outputStream.close();
return user;
} catch (Exception ex) {
throw new CryptoException("Error encrypting/decrypting file", ex);
}
}
}

回答你的问题
请在您的POM.xml中添加spring-security-core作为依赖项
您应该使用spring-security-core-4.0.3.RELEASE.jar中的PasswordEncoder接口来处理您的十六进制数字。
请参考此StandardPasswordEncoder将适合您的情况，也请参考此post将为您提供更多帮助。
此reference document也将为您提供帮助。
