java和mysql加密AES通用，及解決在linux下加密結果不一致問題

private static SecretKeySpec generateMySQLAESKey(final String key, final String encoding) {
		try {
			final byte[] finalKey = new byte[16];
			int i = 0;
			for (byte b : key.getBytes(encoding)) {
				finalKey[i++ % 16] ^= b;
			}
			return new SecretKeySpec(finalKey, "AES");
		} catch (Exception e) {
			throw new RuntimeException(e);
		}
	}

	public static String encryptMysql(String str, String aesKey) {
		try {
			final Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
			// 必定要用上第三個參數，設置一個隨機數種子，不然在linux下某些狀況加密的密文不一致
			SecureRandom secureRandom = new SecureRandom();
			secureRandom.setSeed(1L);
			cipher.init(Cipher.ENCRYPT_MODE, generateMySQLAESKey(aesKey, "UTF-8"), secureRandom);
			return Hex.encodeHexString(cipher.doFinal(str.getBytes("UTF-8"))).toUpperCase();
		} catch (Exception e) {
			log.error("encryptMysql error", e);
		}
		return null;
	}

linux環境下加密密文不一致，這個問題致使有時候能和mysql加密匹配，有時候卻不行，設置一個隨機數種子就能夠了
