ElasticSearch（map数据类型）Java api 增（批量）删改查（全字段、高亮）

前面写了搭建，今天写一篇关于Java api的增删改查以及全字段查询和高亮展示，官方api 地址[https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html]。
一、增
首先添加相应的pom依赖、resource 文件
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.7</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.7</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>transport</artifactId>
<version>5.4.1</version>
</dependency>
resource文件 log4j.properties

###Console ###log4j.appender.console = org.apache.log4j.ConsoleAppenderlog4j.appender.console.Target = System.outlog4j.appender.console.layout = org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern = %d %p[%C:%L]- %m%n

获取一个TransportClient的实例去连接es类似连接数据库代码

Settings settings=Settings.builder().put("cluster.name","yourclustername").build();        TransportClient client = new PreBuiltTransportClient(settings).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("yourhostaddress"), 9300));

Map<String, Object> testMap = new HashMap<>();testMap.put("title","java 编程思想");testMap.put("id",1);//单个Map插入IndexResponse response = client.prepareIndex("索引","yourtype",testMap.get("id")+"").setSource(testMap).get();System.out.println(response.getResult());client.close();

//批量插入List<Map<String,Object>> list = new ArryList<>();for(int i=0;i<10;i++){    testMap.put("id",i);    list.add(testMap);}BulkRequestBuilder bulkRequestBuilder=client.prepareBulk();for (int i=0;i<list.size();i++){            bulkRequestBuilder.add(client.prepareIndex("索引","yourtype").setId(list.get(i).get("id")+"").setSource(list.get(i)));}BulkResponse bulkResponse=bulkRequestBuilder.execute().actionGet();bulkRequestBuilder.request().requests().clear();if (bulkResponse.hasFailures()){    System.out.print("Fail");}System.out.print(bulkResponse.status());client.close();

二、删除

//删除id为0的ES里的数据DeleteResponse response = client.prepareDelete("索引","yourtype","0").get();System.out.print(response.getResult());

三、修改（就是添加ID是里面已有的ID覆盖以前的数据）

//修改ES里id为1的那条数据title改为Tinking in JavatestMap.put("title","Thinking in Java");IndexResponse response = client.prepareIndex("索引","yourtype","1").setSource(testMap).get();System.out.println(response.getResult());client.close();

四、查

QueryBuilder qb = QueryBuilders.multiMatchQuery("yourSearchString","_all");HighlightBuilder highlightBuilder=new HighlightBuilder().field("*").requireFieldMatch(false);highlightBuilder.preTags("<strong style='color:red'>");highlightBuilder.postTags("</strong>");String[] yourTypes={yourTypes};            if (yourTypes==""||yourTypes==null){               yourTypes=new String[0];            }SearchResponse response=client.prepareSearch("索引").setTypes(yourTypes).setFrom(pageIndex).setSize(pageSize).setQuery(qb).highlighter(highlightBuilder).execute().actionGet();            SearchHits searchHits=response.getHits();List<Map> sources=new ArrayList<>();if (searchHits.totalHits>0){    for (SearchHit hit:searchHits){        Map<String,Object> source=hit.getSource();        for (String key:hit.getSource().keySet()){                                                          HighlightField                 highlightField=hit.getHighlightFields().get(key);            if (highlightField!=null){                Text[]fragments=highlightField.fragments();                String value="";                for (Text text:fragments){                    value+=text;                }                            //替换为高亮字段                            source.put(key,value);             }        }    Map<String,Object> esearch=new HashMap<>();    esearch.put("source",esmap);    esearch.put("total",searchHits.totalHits);    sources.add(esearch);}    client.close();    return sources;

索引和type是要你自己去手动填写的，这是我看了官方api写的一个列子 不足之处希望大家多多指教！
今天就写这么多了，大家可以留言互相讨论~晚安~
