如何使用Apache HttpClient处理无效的SSL证书？

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContextBuilder;
import org.apache.http.ssl.TrustStrategy;
import org.apache.http.util.EntityUtils;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLContext;
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

TrustStrategy trustStrategy = new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        return true;
    }
};

SSLContext sslContext = SSLContextBuilder.create()
        .loadTrustMaterial(trustStrategy)
        .build();

SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());

CloseableHttpClient httpClient = HttpClients.custom()
        .setSSLSocketFactory(socketFactory)
        .build();

HttpGet httpGet = new HttpGet("https://example.com");

try {
    HttpResponse response = httpClient.execute(httpGet);
    HttpEntity entity = response.getEntity();
    String content = EntityUtils.toString(entity);
    System.out.println(content);
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        httpClient.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
