关于Java加密解密的问题！

前端传给我密文，我在后端进行解密，然后再进行业务处理，但目前我不会解密，目前我知道加密的方法，如下

    public static String rsaEncrypt(String data, String publicKey) {
        String result = "";
        try {
            // 将Base64编码后的公钥转换成PublicKey对象
            byte[] buffer = Base64.decode(publicKey);
            KeyFactory keyFactory = KeyFactory.getInstance("RSA");
            X509EncodedKeySpec keySpec = new X509EncodedKeySpec(buffer);
            PublicKey pubKey = keyFactory.generatePublic(keySpec);
            // 加密
            Cipher cipher = Cipher.getInstance("RSA");
            cipher.init(Cipher.ENCRYPT_MODE, pubKey);
            byte[] inputArray = data.getBytes();
            int inputLength = inputArray.length;
            System.out.println("加密字节数：" + inputLength);
            // 最大加密字节数，超出最大字节数需要分组加密
            int MAX_ENCRYPT_BLOCK = 117;
            int real = 117;
            // 标识
            int offSet = 0;
            byte[] resultBytes = {};
            byte[] cache = {};
            while (inputLength - offSet > 0) {
                if (inputLength - offSet > MAX_ENCRYPT_BLOCK) {
                    if(!(inputArray[real + offSet] >= 0 && inputArray[real + offSet] <=127)){
                        real = real - 1;
                        continue;
                    }
                    cache = cipher.doFinal(inputArray, offSet, real);
                    offSet += real;
                } else {
                    cache = cipher.doFinal(inputArray, offSet, inputLength - offSet);
                    offSet = inputLength;
                }
                resultBytes = Arrays.copyOf(resultBytes, resultBytes.length + cache.length);
                System.arraycopy(cache, 0, resultBytes, resultBytes.length - cache.length, cache.length);
            }
            result = Base64.encode(resultBytes);
        } catch (Exception e) {
            System.out.println("rsaEncrypt error:" + e.getMessage());
        }
        return result;
    }

请问解密方法该如何写，谢谢
