如何将CryptoJS AES转换成java代码

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

public class CryptoJSToJava {
    public static void main(String[] args) throws Exception {
        String key = "0123456789abcdef"; // 密钥，必须是16字节长度的字符串
        String plaintext = "Hello, World!"; // 明文

        // 加密
        String ciphertext = encryptAES(plaintext, key);
        System.out.println("加密后的密文：" + ciphertext);

        // 解密
        String decryptedText = decryptAES(ciphertext, key);
        System.out.println("解密后的明文：" + decryptedText);
    }

    public static String encryptAES(String plaintext, String key) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        SecretKeySpec secretKey = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), "AES");
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        byte[] encryptedBytes = cipher.doFinal(plaintext.getBytes(StandardCharsets.UTF_8));
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }

    public static String decryptAES(String ciphertext, String key) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        SecretKeySpec secretKey = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), "AES");
        cipher.init(Cipher.DECRYPT_MODE, secretKey);
        byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(ciphertext));
        return new String(decryptedBytes, StandardCharsets.UTF_8);
    }
}
