以下のコードは、自己署名証明書を信頼するために機能します。クライアントを作成するときに TrustSelfSignedStrategy を使用する必要があります。

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
        sslsf).build();

HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
} finally {
    response.close();
}

SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIERを意図的に含めませんでした。ポイントは、自己署名証明書でテストできるようにすることで、認証局から適切な証明書を取得する必要はありませんでした。正しいホスト名で自己署名証明書を簡単に作成できるため、SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIERフラグを追加する代わりに作成してください。

上記のPoolingHttpClientConnectionManagerプロシージャを使用しても機能しない場合、カスタムSSLContextは無視されます。 PoolingHttpClientConnectionManagerを作成するときに、contructorでsocketFactoryRegistryを渡す必要があります。

SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
});
SSLContext sslContext = builder.build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        sslContext, new X509HostnameVerifier() {
            @Override
            public void verify(String Host, SSLSocket ssl)
                    throws IOException {
            }

            @Override
            public void verify(String Host, X509Certificate cert)
                    throws SSLException {
            }

            @Override
            public void verify(String Host, String[] cns,
                    String[] subjectAlts) throws SSLException {
            }

            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder
        .<ConnectionSocketFactory> create().register("https", sslsf)
        .build();

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(
        socketFactoryRegistry);
CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(cm).build();

@mavroprovatoの答えに加えて、自己署名だけでなくすべての証明書を信頼したい場合は（コードのスタイルで）します

builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});

または（自分のコードから直接コピーアンドペースト）：

import javax.net.ssl.SSLContext;
import org.Apache.http.ssl.TrustStrategy;
import org.Apache.http.ssl.SSLContexts;

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

ホスト名の検証もスキップする場合は、設定する必要があります

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

同様に。 （ALLOW_ALL_HOSTNAME_VERIFIERは非推奨です）。

必須の警告：これを実際に行うべきではありません。すべての証明書を受け入れることは悪いことです。ただし、これを行いたい稀なユースケースがいくつかあります。

以前に与えられたコードへの注意として、httpclient.execute（）が例外をスローした場合でも応答を閉じたいでしょう。

CloseableHttpResponse response = null;
try {
    response = httpclient.execute(httpGet);
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
}
finally {
    if (response != null) {
        response.close();
    }
}

上記のコードは、を使用してテストされました

    <groupId>org.Apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.3</version>

Vasektによる回答への小さな追加：

SocketingFactoryRegistryで提供されるソリューションは、PoolingHttpClientConnectionManagerの使用時に機能します。

ただし、プレーンHTTPを介した接続はそれ以降機能しません。 HTTPプロトコル用にPlainConnectionSocketFactoryを追加して、それらを再び機能させる必要があります。

Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();

さまざまなオプションを試した後、httpとhttpsの両方で次の構成が機能しました

        SSLContextBuilder builder = new SSLContextBuilder();
        builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(),SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);


        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", new PlainConnectionSocketFactory())
                .register("https", sslsf)
                .build();


        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
        cm.setMaxTotal(2000);//max connection


        //System.setProperty("jsse.enableSNIExtension", "false"); //""
        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .setConnectionManager(cm)
                .build();

よりシンプルで短い作業コード：

私たちはHTTPClient 4.3.5を使用しており、ほとんどすべてのソリューションがstackoverflowに存在することを試みましたが、何もありません。問題を考えて理解した後、次のコードに行きます。

投稿リクエストを行うために使用するいくつかの方法...

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

    SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

    HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();
    HttpPost postRequest = new HttpPost(url);

通常の形式でHttpPostインスタンスの呼び出しと使用を続けます

「curl --insecure」に相当する上記のテクニックの実用的な蒸留を次に示します。

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

    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    return HttpClients.custom()
            .setSSLSocketFactory(new SSLConnectionSocketFactory(
                    new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(),

Httpクライアント4.5を使用する場合、ホスト名を許可するためにjavasx.net.ssl.HostnameVerifierを使用する必要がありました（テスト目的）。私がやったことは次のとおりです。

CloseableHttpClient httpClient = null;
    try {
        SSLContextBuilder sslContextBuilder = new SSLContextBuilder();
        sslContextBuilder.loadTrustMaterial(null, new TrustSelfSignedStrategy());

        HostnameVerifier hostnameVerifierAllowAll = new HostnameVerifier() 
            {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            };

        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContextBuilder.build(), hostnameVerifierAllowAll);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
            new AuthScope("192.168.30.34", 8443),
            new UsernamePasswordCredentials("root", "password"));

        httpClient = HttpClients.custom()
            .setSSLSocketFactory(sslSocketFactory)
            .setDefaultCredentialsProvider(credsProvider)
            .build();

        HttpGet httpGet = new HttpGet("https://192.168.30.34:8443/axis/services/getStuff?firstResult=0&maxResults=1000");

        CloseableHttpResponse response = httpClient.execute(httpGet);

        int httpStatus = response.getStatusLine().getStatusCode();
        if (httpStatus >= 200 && httpStatus < 300) { [...]
        } else {
            throw new ClientProtocolException("Unexpected response status: " + httpStatus);
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    }
    finally {
        try {
            httpClient.close();
        } catch (IOException ex) {
            logger.error("Error while closing the HTTP client: ", ex);
        }
    }

（私はvasektの答えに直接コメントを追加していましたが、十分な評判ポイントがありません（そこでのロジックはわかりません）

とにかく...私が言いたかったのは、たとえPoolingConnectionを明示的に作成/要求していない場合でも、PoolingConnectionを取得していないということではありません。

元の解決策がうまくいかなかった理由を見つけようとして夢中になりましたが、「私のケースには当てはまらなかった」-間違っているのでvasektの答えを無視しました。

スタックトレースを低く見つめていましたが、真ん中にPoolingConnectionがありました。バング-彼の追加と成功に疲れた!! （私たちのデモは明日であり、私は必死になっていた）:-)
