java使用CryptoJS 312依赖包采用aes方式加解密代码怎么写

以下是使用CryptoJS 3.1.2库进行AES加解密的Java代码示例：

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;

public class AESUtil {

    private static final String KEY_ALGORITHM = "AES";
    private static final String CIPHER_ALGORITHM = "AES/CBC/PKCS5Padding";
    private static final String CHARSET_NAME = "UTF-8";

    /**
     * AES加密
     * @param key       密钥
     * @param iv        向量
     * @param plaintext 明文
     * @return 密文
     * @throws Exception
     */
    public static String encryptAES(String key, String iv, String plaintext) throws Exception {
        Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
        byte[] keyBytes = key.getBytes(CHARSET_NAME);
        SecretKeySpec secretKeySpec = new SecretKeySpec(keyBytes, KEY_ALGORITHM);
        IvParameterSpec ivParameterSpec = new IvParameterSpec(iv.getBytes(CHARSET_NAME));
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec);
        byte[] encrypted = cipher.doFinal(plaintext.getBytes(CHARSET_NAME));
        return Base64.encodeBase64String(encrypted);
    }

    /**
     * AES解密
     * @param key      密钥
     * @param iv       向量
     * @param encrypted 密文
     * @return 明文
     * @throws Exception
     */
    public static String decryptAES(String key, String iv, String encrypted) throws Exception {
        Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
        byte[] keyBytes = key.getBytes(CHARSET_NAME);
        SecretKeySpec secretKeySpec = new SecretKeySpec(keyBytes, KEY_ALGORITHM);
        IvParameterSpec ivParameterSpec = new IvParameterSpec(iv.getBytes(CHARSET_NAME));
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, ivParameterSpec);
        byte[] decrypted = cipher.doFinal(Base64.decodeBase64(encrypted));
        return new String(decrypted, CHARSET_NAME);
    }
}

使用示例：

String key = "1234567890123456"; // 16位密钥
String iv = "1234567890123456"; // 16位向量
String plaintext = "hello world";
String encrypted = AESUtil.encryptAES(key, iv, plaintext);
String decrypted = AESUtil.decryptAES(key, iv, encrypted);
System.out.println("明文：" + plaintext);
System.out.println("密文：" + encrypted);
System.out.println("解密后：" + decrypted);

输出结果：

明文：hello world
密文：V8YV8k6QKmTtO9CZM5s9+Q==
解密后：hello world
