在java项目中编写加密和解密文本的方法

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

public class EncryptionUtils {
    private static final String ALGORITHM = "AES";
    private static final String SECRET_KEY = "YourSecretKey"; // 密钥，需要保密

    public static String encrypt(String text) throws Exception {
        SecretKeySpec secretKeySpec = new SecretKeySpec(SECRET_KEY.getBytes(StandardCharsets.UTF_8), ALGORITHM);
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
        byte[] encryptedBytes = cipher.doFinal(text.getBytes(StandardCharsets.UTF_8));
        return Base64.getEncoder().encodeToString(encryptedBytes);
    }

    public static String decrypt(String encryptedText) throws Exception {
        SecretKeySpec secretKeySpec = new SecretKeySpec(SECRET_KEY.getBytes(StandardCharsets.UTF_8), ALGORITHM);

    }
}

public class Main {
    public static void main(String[] args) {
        try {
            String originalText = "Hello, World!";
            String encryptedText = EncryptionUtils.encrypt(originalText);
