Encrypted communicationedit
Encrypted communication can also be configured through the
HttpClientConfigCallback. The
org.apache.http.impl.nio.client.HttpAsyncClientBuilder
received as an argument exposes multiple methods to configure encrypted
communication: setSSLContext, setSSLSessionStrategy and
setConnectionManager, in order of precedence from the least important.
The following is an example:
KeyStore keyStore = KeyStore.getInstance("jks");
try (InputStream is = Files.newInputStream(keyStorePath)) {
keyStore.load(is, keyStorePass.toCharArray());
}
RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200))
.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder.setSSLContext(sslcontext);
}
})
.build();
