Is there a way to ignore SSL certificate verification while connecting elasticsearch 7.4 using high level rest client. I explored a couple of options but nothing worked in my case. I have a HTTPS ES cluster which I want to connect from my spring boot application by ignoring ssl certificate verification.

希望能帮到你，我遇到了同样的问题，我就是这样解决的.
hope this will help you, I had the same problem and this is how I resolved.
@Bean
public RestHighLevelClient createSimpleElasticClient() throws Exception {
try {
SSLContextBuilder sslBuilder = SSLContexts.custom()
.loadTrustMaterial(null, (x509Certificates, s) -> true);
final SSLContext sslContext = sslBuilder.build();
RestHighLevelClient client = new RestHighLevelClient(RestClient
.builder(new HttpHost(hostNameOrLoadbalancerURL, 443, "https"))
//port number is given as 443 since its https schema
.setHttpClientConfigCallback(new HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder
.setSSLContext(sslContext)
.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE);
}
})
.setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
@Override
public RequestConfig.Builder customizeRequestConfig(
RequestConfig.Builder requestConfigBuilder) {
return requestConfigBuilder.setConnectTimeout(5000)
.setSocketTimeout(120000);
}
}));
System.out.println("elasticsearch client created");
return client;
} catch (Exception e) {
System.out.println(e);
throw new Exception("Could not create an elasticsearch client!!");
}
}
