在Storm中實現數據的加密和解密可以通過使用加密算法和解密算法對數據進行處理。以下是一種可能的實現方式:
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
public class EncryptionUtil {
private static final String ALGORITHM = "AES";
private static final String KEY = "YourSecretKey";
public static byte[] encrypt(byte[] data) {
try {
SecretKey secretKey = new SecretKeySpec(KEY.getBytes(), ALGORITHM);
Cipher cipher = Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.ENCRYPT_MODE, secretKey);
return cipher.doFinal(data);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
public class DecryptionUtil {
private static final String ALGORITHM = "AES";
private static final String KEY = "YourSecretKey";
public static byte[] decrypt(byte[] encryptedData) {
try {
SecretKey secretKey = new SecretKeySpec(KEY.getBytes(), ALGORITHM);
Cipher cipher = Cipher.getInstance(ALGORITHM);
cipher.init(Cipher.DECRYPT_MODE, secretKey);
return cipher.doFinal(encryptedData);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
在Storm拓撲中,可以在需要加密或解密數據的地方調用相應的加密和解密方法,對數據進行處理。例如,在Spout或Bolt中處理數據前先加密,處理完成后再解密。
