我在解密文本時遇到了一些問題：我的后端在解密過程中經常拋出 IllegalBlockSizeException：javax.crypto.IllegalBlockSizeException: Input length must be multiple of 16 when decrypting with padded cipher當我再次嘗試（1-3 次）時，它終于可以成功解密 SAME 文本并將響應發(fā)送給 FE。正如我注意到的那樣，當我嘗試在短時間內解密許多（大約 100 個）字符串時，通常會發(fā)生這種情況（2 個請求來自 FE，從 db/請求查詢 15 個記錄，2 個加密字段/記錄）我的服務器在帶有 Raspbian 的 Raspberry Pi B+ 上運行?！捌胀ā盤C 上不存在此問題。加密類：package bookmarks.common.encryption.base;import java.nio.charset.StandardCharsets;import java.security.InvalidKeyException;import java.security.Key;import java.security.NoSuchAlgorithmException;import javax.crypto.BadPaddingException;import javax.crypto.Cipher;import javax.crypto.IllegalBlockSizeException;import javax.crypto.NoSuchPaddingException;import javax.crypto.spec.SecretKeySpec;import org.apache.commons.net.util.Base64;import lombok.extern.slf4j.Slf4j;@Slf4jpublic class DefaultEncryptor {    private static final int SIZE = 16;    private static final String ALGORITHM = "AES";    private static final Base64 BASE_64 = new Base64();    private final Key key;    private final Cipher cipher;    public DefaultEncryptor(String password) {        byte[] key = createKey(password);        this.key = new SecretKeySpec(key, ALGORITHM);        try {            cipher = Cipher.getInstance(ALGORITHM);        } catch (NoSuchAlgorithmException | NoSuchPaddingException e) {            log.error("Error creating encryptor.", e);            throw new RuntimeException(e);        }    }    private byte[] createKey(String password) {        if (password.length() < SIZE) {            int missingLength = SIZE - password.length();            StringBuilder passwordBuilder = new StringBuilder(password);            for (int i = 0; i < missingLength; i++) {                passwordBuilder.append(" ");            }            password = passwordBuilder.toString();        }        return password.substring(0, SIZE).getBytes(StandardCharsets.UTF_8);    }有什么想法會導致問題嗎？
