我正在使用低级 rest API 访问 AWS 中的 Elastic Search(AWS 服务)。 AWS 提供 HTTPS url。以下代码位于名为 com.example.configurations.EsConfig
的 SpringBoot 配置类中。
@Bean
public RestClient restClient() throws Exception {
RestClient restClient = RestClient.builder(new HttpHost(esHost, esPort))
.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
HttpAsyncClientBuilder httpAsyncClientBuilder = null;
try {
httpAsyncClientBuilder = httpClientBuilder.setSSLContext(SSLContext.getDefault());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return httpAsyncClientBuilder;
}
})
.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(5000)
.setSocketTimeout(60000))
.setMaxRetryTimeoutMillis(60000)
.build();
return restClient;
}
对于 esHost,我仅像本地主机一样提供 AWS Elasticsearch 端点 URL。
对于 esPort,在 HTTPS 的情况下为 443。
错误信息如下:

我无法通过 SSL 连接获取 RestClient。请建议我通过 SSL 连接获得 RestClient 需要什么。 谢谢
最佳答案
我在创建 HttpPost 对象作为第三个参数时解决了传递“https”的问题。
RestClient restClient = RestClient.builder(new HttpHost(esHost, esPort, "https"))
.setHttpClientConfigCallback(httpClientBuilder -> {
HttpAsyncClientBuilder httpAsyncClientBuilder = httpClientBuilder.setSSLContext(sslcontext);
return httpAsyncClientBuilder;
})
.build();
现在它工作正常。
