那就麻烦你给我提供一个AES的java工具类， 并且使用ECB加密，zeroPadding填充, 数据块为128位, 密码为 1234567890abcdef

以下是一个使用AES/ECB/ZeroPadding加密的Java工具类示例：

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class AESUtil {
    private static final String ALGORITHM = "AES";
    private static final String TRANSFORMATION = "AES/ECB/ZeroPadding";

    public static String encrypt(String plainText, String password) throws Exception {
        SecretKeySpec secretKeySpec = generateKey(password);
        Cipher cipher = Cipher.getInstance(TRANSFORMATION);
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
        byte[] encryptedBytes = cipher.doFinal(padString(plainText).getBytes());
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }

    public static String decrypt(String encryptedText, String password) throws Exception {
        SecretKeySpec secretKeySpec = generateKey(password);
        Cipher cipher = Cipher.getInstance(TRANSFORMATION);
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec);
        byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(encryptedText));
        return removePadding(new String(decryptedBytes, StandardCharsets.UTF_8));
    }

    private static SecretKeySpec generateKey(String password) throws Exception {
        byte[] keyBytes = password.getBytes(StandardCharsets.UTF_8);
        return new SecretKeySpec(keyBytes, ALGORITHM);
    }

    private static String padString(String input) {
        int paddingLength = 16 - (input.length() % 16);
        StringBuilder paddedInput = new StringBuilder(input);
        for (int i = 0; i < paddingLength; i++) {
            paddedInput.append('\0');
        }
        return paddedInput.toString();
    }

    private static String removePadding(String input) {
        return input.replaceAll("\0+$", "");
    }

    public static void main(String[] args) {
        try {
            String plainText = "Hello, World!";
            String password = "1234567890abcdef";

            String encryptedText = encrypt(plainText, password);
            System.out.println("Encrypted Text: " + encryptedText);

            String decryptedText = decrypt(encryptedText, password);
            System.out.println("Decrypted Text: " + decryptedText);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

上述代码使用了AES/ECB/ZeroPadding加密算法，并提供了`encrypt`和`decrypt`方法用于加密和解密操作。在示例中，明文为"Hello, World!"，密码为"1234567890abcdef"。运行代码后，会输出加密后的密文和解密后的明文。请注意，使用ECB模式并且只使用ZeroPadding填充可能会存在安全性问题，建议使用更加安全的加密模式和填充方式。
