如何使用Java中的SSL和pkcs12文件连接到安全的网站？

import javax.net.ssl.*;
import java.io.FileInputStream;
import java.io.IOException;
import java.security.*;
import java.security.cert.CertificateException;

// 读取PKCS12文件
KeyStore keyStore = KeyStore.getInstance("PKCS12");
FileInputStream keyStoreFile = new FileInputStream("path/to/your/certificate.p12");
String keyStorePassword = "yourKeyStorePassword";
keyStore.load(keyStoreFile, keyStorePassword.toCharArray());

// 获取密钥管理器
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, keyStorePassword.toCharArray());

// 创建SSL上下文
SSLContext sslContext = SSLContext.getInstance("TLS");

// 初始化SSL上下文
sslContext.init(keyManagerFactory.getKeyManagers(), null, new SecureRandom());

// 创建套接字工厂
SSLSocketFactory socketFactory = sslContext.getSocketFactory();

// 设置默认的套接字工厂
HttpsURLConnection.setDefaultSSLSocketFactory(socketFactory);

// 创建URL对象
URL url = new URL("https://your-secure-website.com");

// 打开连接
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();

// 设置请求方法
connection.setRequestMethod("GET");

// 读取响应
InputStream inputStream = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
    response.append(line);
    response.append("\n");
}
reader.close();

// 输出响应
System.out.println(response.toString());
