Wyłączanie walidacji certyfikatu SSL w Spring RestTemplate
Mam dwie aplikacje webowe a i B oparte na sprężynach, na dwóch różnych maszynach.
Chcę nawiązać połączenie https z aplikacji internetowej a do aplikacji internetowej b, jednak używam certyfikatu z podpisem własnym w maszynie B. więc moje żądanie HTTPS nie powiedzie się.
Jak wyłączyć walidację certyfikatu https podczas korzystania z RestTemplate na wiosnę ? Chcę wyłączyć sprawdzanie poprawności, ponieważ zarówno aplikacja internetowa a, jak i B znajdują się w sieci wewnętrznej, ale transfer danych musi odbywać się przez HTTPS

To, co musisz dodać, to niestandardowa klasa HostnameVerifier
omija weryfikację certyfikatu i zwraca true
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
To musi być umieszczone odpowiednio w Twoim kodzie.

Zasadniczo dwie rzeczy, które musisz zrobić, to użyć custom TrustStrategy, która ufa wszystkim certom, a także użyć NoopHostnameVerifier () aby wyłączyć weryfikację nazwy hosta. Oto Kod, ze wszystkimi odpowiednimi importami:
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
public RestTemplate getRestTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
TrustStrategy acceptingTrustStrategy = new TrustStrategy() {
@Override
public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
return true;
}
};
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
RestTemplate restTemplate = new RestTemplate(requestFactory);
return restTemplate;
}

Add my response with cookie :
public static void main(String[] args) {
MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
params.add("username", testUser);
params.add("password", testPass);
NullHostnameVerifier verifier = new NullHostnameVerifier();
MySimpleClientHttpRequestFactory requestFactory = new MySimpleClientHttpRequestFactory(verifier , rememberMeCookie);
ResponseEntity<String> response = restTemplate.postForEntity(appUrl + "/login", params, String.class);
HttpHeaders headers = response.getHeaders();
String cookieResponse = headers.getFirst("Set-Cookie");
String[] cookieParts = cookieResponse.split(";");
rememberMeCookie = cookieParts[0];
cookie.setCookie(rememberMeCookie);
requestFactory = new MySimpleClientHttpRequestFactory(verifier,cookie.getCookie());
restTemplate.setRequestFactory(requestFactory);
}
public class MySimpleClientHttpRequestFactory extends SimpleClientHttpRequestFactory {
private final HostnameVerifier verifier;
private final String cookie;
public MySimpleClientHttpRequestFactory(HostnameVerifier verifier ,String cookie) {
this.verifier = verifier;
this.cookie = cookie;
}
@Override
protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
if (connection instanceof HttpsURLConnection) {
((HttpsURLConnection) connection).setHostnameVerifier(verifier);
((HttpsURLConnection) connection).setSSLSocketFactory(trustSelfSignedSSL().getSocketFactory());
((HttpsURLConnection) connection).setAllowUserInteraction(true);
String rememberMeCookie = cookie == null ? "" : cookie;
((HttpsURLConnection) connection).setRequestProperty("Cookie", rememberMeCookie);
}
super.prepareConnection(connection, httpMethod);
}
public SSLContext trustSelfSignedSSL() {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLContext.setDefault(ctx);
return ctx;
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
}
public class NullHostnameVerifier implements HostnameVerifier {
public boolean verify(String hostname, SSLSession session) {
return true;
}
}

Możesz użyć tego z HTTPClient API.
public RestTemplate getRestTemplateBypassingHostNameVerifcation() {
CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
return new RestTemplate(requestFactory);
}
