Java 代码实现 elasticsearch 增 查

　　
指定索引 插入数据

 RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("192.168.10.129", 9200)));
       IndexRequest indexRequest = new IndexRequest();
　　　　//指定索引
       indexRequest.index("test_2022_9_7");
       User user = new User();
       user.setAddr("test_addr");
       user.setAge(23);
       user.setId(4);
       user.setName("test");

       ObjectMapper mappers = new ObjectMapper();
       String s = mappers.writeValueAsString(user);
       indexRequest.source(s, XContentType.JSON);
       indexRequest.type("_doc");
       IndexResponse index = client.index(indexRequest, RequestOptions.DEFAULT);
       System.out.printf(String.valueOf(index.getResult()));

//查询条件  addr 字段值为test 的数据

        RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("192.168.10.129", 9200)));

　　　　 GetRequest request = new GetRequest();
        request.index("test_2022_9_7").id("1");
        SearchSourceBuilder builder = new SearchSourceBuilder();
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();

        boolQueryBuilder.must(QueryBuilders.matchQuery("addr","test"));

        builder.query(boolQueryBuilder);
        GetResponse response = client.get(request, RequestOptions.DEFAULT);
        System.out.println(response.getSourceAsString());
