Encrypted communication
edit
IMPORTANT: This documentation is no longer updated. Refer to Elastic's version policy and the latest documentation.
Encrypted communication
editEncrypted 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 truststore = KeyStore.getInstance("jks");
try (InputStream is = Files.newInputStream(keyStorePath)) {
truststore.load(is, keyStorePass.toCharArray());
}
SSLContextBuilder sslBuilder = SSLContexts.custom()
.loadTrustMaterial(truststore, null);
final SSLContext sslContext = sslBuilder.build();
RestClientBuilder builder = RestClient.builder(
new HttpHost("localhost", 9200, "https"))
.setHttpClientConfigCallback(new HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(
HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder.setSSLContext(sslContext);
}
});
If no explicit configuration is provided, the system default configuration will be used.
