1：ES根據(jù)單個條件查詢

public String searchEsAttachmentsLink(String riskId,String dataFrom){
try {
//添加條件，
    SearchSourceBuilder searchSourceBuilder = SearchSourceBuilder.searchSource()
            .size(1)
            .query(QueryBuilders.termQuery( name: "字段"， 值));
//拼裝
    SearchRequest searchRequest = new SearchRequest()
        .indices(索引)
        .source(searchSourceBuilder);
//用ESClient執(zhí)行search，得到響應(yīng)結(jié)果
    SearchResponse searchResponse =         
    restHighLevelClient.search(searchRequest,RequestOption.DEFAULT);
//根據(jù)自己返回的數(shù)據(jù)格式取值
    SearchHit[] hits = searchResponse.getHits().getHits();
    for (SearchHit hit : hits) {
//取值
        hit.getSourceAsMap().get("字段");
    }
    

       return null;
}

2:ES根據(jù)多個條件查詢

BoolOueryBuilder boolOueryBuilder = new BoolOueryBuilder();
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
//用must拼接where條件
boolQueryBuilder.must(QueryBuilders.termQuery("字段"，"值"))
                .must(QueryBuilders.termQuery("字段","值");
SearchRequest searchRequest = new SearchRequest()
            .indices(索引)
            .source(searchSourceBuilder);
searchSourceBuilder.query(boolQueryBuilder);
log.info("拼接后的請求參數(shù): ",searchRequest);
SearchResponse searchResponse = restHighLevelclient.search(searchRequest,RequestOptions .DEFAULT) ;
log.info("查詢后的結(jié)果: ",searchResponse);
//取值
SearchHitl] hits = searchResponse.getHits() .getHits();

3：ES根據(jù)id，局部更新文檔

UpdateRequest updateRequest = new UpdateRequest();
updateRequest.index(索引);
updateRequest.type("_doc");
updateRequest.id(id);
//添加where條件
updateRequest.doc(
        XContentFactory.jsonBuilder(
                .startobject()
                .field( "字段"， "值")
                .field( "字段"， "值")
                .endobject()
    );
//執(zhí)行
String resultUpdate = restHighlevelClient.update(updateRequest, Request0ptions.DEFAULT).getResult().tostring();

到了這里，關(guān)于java實現(xiàn) elasticsearch es 的單個條件查詢和多個條件查詢，根據(jù)id更新指定字段的文章就介紹完了。如果您還想了解更多內(nèi)容，請在右上角搜索TOY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
