public class ESTest_Doc_Update {
    public static void main(String[] args) throws Exception {
        //创建ES客户端
        RestHighLevelClient esClient = new RestHighLevelClient(
                RestClient.builder(new HttpHost("localhost",9200,"http"))
        );

        //修改数据
        UpdateRequest request = new UpdateRequest();

        request.index("user").id("1002");
        request.doc(XContentType.JSON,"sex","女");

        UpdateResponse response = esClient.update(request, RequestOptions.DEFAULT);

        System.out.println(response.getResult());

        //关闭ES客户端
