如何在Java中加密字符串，在Python中解密？

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import java.util.Base64;

public class EncryptionExample {
    public static void main(String[] args) throws Exception {
        String plaintext = "Hello, World!";
        String key = "ThisIsASecretKey";

        // 创建AES加密算法实例
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

        // 创建密钥规范
        SecretKeySpec secretKey = new SecretKeySpec(key.getBytes(), "AES");

        // 初始化加密模式
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);

        // 加密字符串
        byte[] encryptedBytes = cipher.doFinal(plaintext.getBytes());

        // 将加密结果转换为Base64编码的字符串
        String encryptedText = Base64.getEncoder().encodeToString(encryptedBytes);

        System.out.println("加密后的字符串：" + encryptedText);
    }
}

decrypted_text = decrypt(encrypted_text, key)
print("解密后的字符串：" + decrypted_text)
