上文已经教了大家最基本的操作了,那我们在java代码里面要如何实现呢?本文的目的就是教大家在springboot框架下实现上文的API操作,也就是CURD!
环境准备
首先我们要知道ES的API都是HTTP请求!!!!,所以什么语言都可以操作,就是发送请求和处理返回而已嘛,只是说现在这种封装不需要我们做,有人做好了,这种叫做ES的客户端!
依赖配置
我们直接采用Spring-data-es的依赖,先看一下版本依赖说明:
这里建议客户端版本和你自身搭建的es版本保持一致(es不同版本间api差异很大,如果不想出现莫名其妙的错的最好一致),所以这里我们选择springboot 2.3版本,这里给出spring-data-es的官方文档
# springboot版本
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
# spring-elasticsearch依赖
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
<version>4.0.9.RELEASE</version>
</dependency>
因为我这ES是7.6的,所以选择使用HighLevelRestClient客户端,虽然这个已经在高版本过时了(8.x),但是在7.x版本里面官方建议使用这个
项目引入依赖后,使用非常简单,文件中配置一下ES地址,就可以愉快的访问啦:
# yml配置文件
spring:
elasticsearch:
rest:
uris: ip:port
username:

实体类准备

@Document(indexName = "es_apply_test")

-
注解:@Document用来声明Java对象与ElasticSearch索引的关系
indexName 索引名称
type 索引类型
shards 主分区数量
replicas 副本分区数量
createIndex 索引不存在时,是否自动创建索引,默认true
不建议自动创建索引(自动创建的索引 是按着默认类型和默认分词器)
-
注解:@Id 表示索引的主键
-
注解:@Field 用来描述字段的ES数据类型,是否分词等配置,等于Mapping描述
index 设置字段是否索引,默认是true,如果是false则该字段不能被查询
store 默认为no,被store标记的fields被存储在和index不同的fragment中,以便于快速检索。虽然store占用磁盘空间,但是减少了计算。
type 数据类型(text、keyword、date、object、geo等)
analyzer 对字段使用分词器,注意一般如果要使用分词器,字段的type一般是text。
format 定义日期时间格式,详细见 官方文档: https://www.elastic.co/guide/reference/mapping/date-format/.
-
注解:@CompletionField 定义关键词索引 要完成补全搜索
analyzer 对字段使用分词器,注意一般如果要使用分词器,字段的type一般是text。
searchAnalyzer 显示指定搜索时分词器,默认是和索引是同一个,保证分词的一致性。
maxInputLength:设置单个输入的长度,默认为50 UTF-16 代码点
使用说明
我们引入依赖后,在使用的时候有四种使用方式(下面我由简→难说明一下):
- ElasticsearchRepository:自动生成简单CURD方法,直接调用即可(复杂的不友好)
- ElasticsearchRestTemplate:内部使用的是RestHighLevelClient,它帮我们封装了一层
- RestHighLevelClient:直接使用客户端
- 自己封装客户端:之前说了本质就是HTTP请求,自己封装一下,直接调API呗,这比啥都好使
本文使用ElasticsearchRestTemplate(对小白友好),但是我个人强烈推荐直接用RestHighLevelClient,因为这个支持得更全面还同时支持同步和异步操作,本文有些操作也会用到这个
本文索引名称:es_apply_test
客户端注入:
索引/映射操作
创建索引和映射
@Test
void createIndexAndMapping() {
IndexOperations indexOperations = elasticsearchRestTemplate.indexOps(EsTest.class);
// 判断索引是否已经存在
if(!indexOperations.exists()){
// 不存在则创建
indexOperations.create();
Document mapping = indexOperations.createMapping(EsTest.class);
indexOperations.putMapping(mapping);
}
log.info("使用API查询查看..................");
}
索引和映射相关查询
@Test
void queryIndexAndMapping() {
IndexOperations indexOperations = elasticsearchRestTemplate.indexOps(EsTest.class);
boolean exists = indexOperations.exists();
log.info("索引是否存在:{}",exists);
Map<String, Object> mapping = indexOperations.getMapping();
log.info("映射:{}",JSONObject.toJSONString(mapping));
Map<String, Object> settings = indexOperations.getSettings();
log.info("索引设置:{}",JSONObject.toJSONString(settings));
// 索引刷新(这个功能用处,后面讲理论的时候你会知道是干嘛的)
indexOperations.refresh();
}
删除索引
@Test
void deletedIndex() {
IndexOperations indexOperations = elasticsearchRestTemplate.indexOps(EsTest.class);
indexOperations.delete();
}
文档操作
插入数据
/** 插入一条数据 */
@Test
void insertDoc() {
// 插入一条
elasticsearchRestTemplate.save(EsTest.getRandomData(1L));
// 同时插入多条 实际是遍历一条一条插入而不是用的bulk命令
elasticsearchRestTemplate.save(EsTest.getRandomData(2L),EsTest.getRandomData(3L));
}
更新数据
/** 更新数据 */
@Test
void updateDoc() throws IOException {
// es的数据结构都是文档,其实不存在文档更新,每次更新都会产生新的文档(这个是很低效的),所以es在API方面也看的出来对更新不是很友好
// 没办法,虽然更新很低效,但终究得改呀
// 下面提供几种方式
// 1.根据ID更新
UpdateQuery build = UpdateQuery.builder("1").withDocument(Document.parse("{ \"name\": \"根据ID更新\" }")).build();
elasticsearchRestTemplate.update(build,elasticsearchRestTemplate.getIndexCoordinatesFor(EsTest.class));
// 2.条件更新
// 采用highLevel客户端,根据查询条件 使用脚本更新 等同于_update_by_query API
UpdateByQueryRequest request = new UpdateByQueryRequest("es_apply_test");
request.setQuery(QueryBuilders.termQuery("age","24"));
request.setScript(new Script("ctx._source['age']='300';ctx._source['remark']='根据条件批量更新';"));
restHighLevelClient.updateByQuery(request, RequestOptions.DEFAULT);
}
删除数据
/** 删除数据 */
@Test
void deleteDoc() throws IOException {
// 1.根据ID删除
elasticsearchRestTemplate.delete("1",EsTest.class);
// 2.条件删除
NativeSearchQuery build = new NativeSearchQueryBuilder().withQuery(QueryBuilders.termQuery("id", "3")).build();
elasticsearchRestTemplate.delete(build,EsTest.class,elasticsearchRestTemplate.getIndexCoordinatesFor(EsTest.class));
}
批量操作
/** 批量增、删、改操作 */
@Test
void bulkDoc() throws IOException {
// 量大的话强烈推荐这种方式,因为ES本身是以查询突出,修改的吞吐量并不高
// 1. 批量插入
BulkRequest insertRequest = new BulkRequest();
for(int i=1;i<=20;i++){
IndexRequest indexRequest = new IndexRequest("es_apply_test");
indexRequest.id(String.valueOf(i));
indexRequest.source(JSONObject.toJSONString(EsTest.getRandomData((long)i)),XContentType.JSON);
insertRequest.add(indexRequest);
}
BulkResponse insertResult = restHighLevelClient.bulk(insertRequest, RequestOptions.DEFAULT);
log.info("是否失败: {},失败原因:{}",insertResult.hasFailures(),insertResult.buildFailureMessage());
// 2. 批量更新
BulkRequest updateRequest = new BulkRequest();
for(int i=1;i<=5;i++){
UpdateRequest indexRequest = new UpdateRequest();
indexRequest.id(String.valueOf(i));
indexRequest.index("es_apply_test");
HashMap<String, Object> objectObjectHashMap = new HashMap<>();
objectObjectHashMap.put("name","bulk批量更新");
indexRequest.doc(objectObjectHashMap);
updateRequest.add(indexRequest);
}
BulkResponse updateResult = restHighLevelClient.bulk(updateRequest, RequestOptions.DEFAULT);
log.info("是否失败: {},失败原因:{}",updateResult.hasFailures(),updateResult.buildFailureMessage());
// 3. 批量删除
BulkRequest deleteRequest = new BulkRequest();
for(int i=1;i<=5;i++){
DeleteRequest request = new DeleteRequest();
request.id(String.valueOf(i));
request.index("es_apply_test");
updateRequest.add(request);
}
BulkResponse deleteResult = restHighLevelClient.bulk(deleteRequest, RequestOptions.DEFAULT);
log.info("是否失败: {},失败原因:{}",deleteResult.hasFailures(),deleteResult.buildFailureMessage());
// 当然也可混合操作 就是 _bulk API
}
文档查询
