本文介绍了使用Java进行Elasticsearch索引管理的方法，包括删除、创建索引及检查索引存在状态的功能实现。

public class EsUtil{
	// 删除索引
    protected boolean deleteIndies(RestHighLevelClient client, String indexName) throws IOException {
        DeleteIndexRequest index = new DeleteIndexRequest(indexName);
        if (existIndies(client, indexName)) {
            AcknowledgedResponse delete = client.indices().delete(index, RequestOptions.DEFAULT);
            return delete.isAcknowledged();
        }
        return false;
    }

    // 创建索引
    protected boolean createIndies(RestHighLevelClient client, String indexName) throws IOException {
        CreateIndexRequest index = new CreateIndexRequest(indexName);
        CreateIndexResponse create = client.indices().create(index, RequestOptions.DEFAULT);
        return create.isAcknowledged();
    }

    // 判断索引是否存在
    protected boolean existIndies(RestHighLevelClient client, String indexName) throws IOException {
        GetIndexRequest index = new GetIndexRequest(indexName);
        return client.indices().exists(index, RequestOptions.DEFAULT);
    }
}
