在RestHighLevelClient中增加用户名密码验证

@Configuration
public class ElasticSearchClient {
    @Value("${ElasticSearch.Hosts}")
    private String hosts;
    @Value("${ElasticSearch.UserName}")
    private String userName;
    @Value("${ElasticSearch.Password}")
    private String password;
    
    @SuppressWarnings("deprecation")
    @Bean(name="esClient")
    public RestHighLevelClient getClient() {
        String[] hosts = this.hosts.split(",");
        HttpHost[] httpHosts = new HttpHost[hosts.length];
        for(int i=0;i<hosts.length;i++) {
            httpHosts[i] = new HttpHost(hosts[i], 9200, "http");
        }
        
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(userName, password));
        
        RestClientBuilder builder = RestClient.builder(httpHosts).setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
            @Override
            public RequestConfig.Builder customizeRequestConfig(RequestConfig.Builder requestConfigBuilder) {
                requestConfigBuilder.setConnectTimeout(-1);
                requestConfigBuilder.setSocketTimeout(-1);
                requestConfigBuilder.setConnectionRequestTimeout(-1);
                return requestConfigBuilder;
            }
        }).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
            @Override
            public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                httpClientBuilder.disableAuthCaching();
                return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
            }
        }).setMaxRetryTimeoutMillis(5*60*1000);
        
        RestHighLevelClient client = new RestHighLevelClient(builder);
