elasticsearch安装和使用ik分词器，分享Java资深架构师的成长之路

import org.elasticsearch.client.RestHighLevelClient;

public class ElasticsearchExample {
    public static void main(String[] args) throws IOException {
        // 初始化Elasticsearch客户端
        RestClientBuilder builder = RestClient.builder(
                new HttpHost("localhost", 9200, "http"));
        RestHighLevelClient client = new RestHighLevelClient(builder);
 
        // 检查Elasticsearch集群的健康状态
        ClusterHealthRequest request = new ClusterHealthRequest();
        ClusterHealthResponse response = client.cluster().health(request, RequestOptions.DEFAULT);
        System.out.println("Elasticsearch cluster health: " + response.getStatus());
 
        // 关闭Elasticsearch客户端
        client.close();
    }
}

这段代码演示了如何使用Elasticsearch Java API连接到本地运行的Elasticsearch实例，并检查集群的健康状态。在实际使用中，你需要根据自己的Elasticsearch服务器地址和端口进行相应的调整。这个简单的例子可以作为开始使用Elasticsearch Java API的基础。
