如何在Java中禁用Elasticsearch RestClient v6.7.0的SSL验证

ChatGPT的回答仅作参考：

可以通过以下方式禁用Elasticsearch RestClient v6.7.0的SSL验证：

1. 创建一个SSL上下文，禁用SSL验证：

```
SSLContext sslContext = SSLContexts.custom()
        .loadTrustMaterial(null, (chain, authType) -> true)
        .build();
```

2. 创建一个HTTP客户端，使用上面创建的SSL上下文：

```
CloseableHttpClient httpClient = HttpClients.custom()
        .setSSLContext(sslContext)
        .build();
```

3. 创建一个RestClient，使用上面创建的HTTP客户端：

```
RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200))
        .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setSSLContext(sslContext))
        .build();
```

完整代码示例：

```
import org.apache.http.HttpHost;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLContexts;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.elasticsearch.client.RestClient;
import javax.net.ssl.SSLContext;

public class ElasticsearchClient {
    public static void main(String[] args) throws Exception {
        SSLContext sslContext = SSLContexts.custom()
                .loadTrustMaterial(null, (chain, authType) -> true)
                .build();

        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLContext(sslContext)
                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                .build();

        RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200))
                .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setSSLContext(sslContext))
                .build();

        // 使用restClient进行操作

        restClient.close();
    }
}
```
