请写出一个java的aes加密解密工具类并写出对应的vue的aes加密解密工具类

由于AES加密解密涉及到安全性，建议使用官方提供的Java Cryptography Extension (JCE)库进行操作。以下是一个基于JCE库实现的Java AES加密解密工具类：

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/PKCS5Padding";

    /**
     * AES加密
     * @param plainText 明文
     * @param key 密钥
     * @return 密文
     * @throws Exception 异常
     */
    public static String encrypt(String plainText, String key) throws Exception {
        SecretKeySpec secretKeySpec = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), ALGORITHM);
        Cipher cipher = Cipher.getInstance(TRANSFORMATION);
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
        byte[] encryptedBytes = cipher.doFinal(plainText.getBytes(StandardCharsets.UTF_8));
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }

    /**
     * AES解密
     * @param cipherText 密文
     * @param key 密钥
     * @return 明文
     * @throws Exception 异常
     */
    public static String decrypt(String cipherText, String key) throws Exception {
        SecretKeySpec secretKeySpec = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), ALGORITHM);
        Cipher cipher = Cipher.getInstance(TRANSFORMATION);
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec);
        byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(cipherText));
        return new String(decryptedBytes, StandardCharsets.UTF_8);
    }

}

以下是一个基于JavaScript的Vue AES加密解密工具类：

import CryptoJS from 'crypto-js';

const key = CryptoJS.enc.Utf8.parse("1234567890123456"); // 密钥长度必须为16、24或32位

export default {
    /**
     * AES加密
     * @param plainText 明文
     * @returns 密文
     */
    encrypt: function (plainText) {
        const encrypted = CryptoJS.AES.encrypt(plainText, key, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        return encrypted.toString();
    },

    /**
     * AES解密
     * @param cipherText 密文
     * @returns 明文
     */
    decrypt: function (cipherText) {
        const decrypted = CryptoJS.AES.decrypt(cipherText, key, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        return decrypted.toString(CryptoJS.enc.Utf8);
    }
}
