1、引入maven(注意版本要一致)
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-elasticsearch</artifactId> </dependency> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>6.4.3</version> </dependency>
2、配置.properties
spring.elasticsearch.rest.uris=http://127.0.0.1:9200 spring.elasticsearch.rest.password= spring.elasticsearch.rest.username=
3、使 @Autowired
private RestHighLevelClient restHighLevelClient; private void bulkPutIndex(List<Map<String, Object>> list ) throws IOException { if (JudgeUtil.isEmpty(list)){ return; } String index = "test"; String type = "test"; int size = list.size(); BulkRequest request = new BulkRequest(); for (int i = 0; i < size; i++) { Map<String, Object> map = list.get(i); //这里必须每次都使用new IndexRequest(index,type),不然只会插入最后一条记录(这样插入不会覆盖已经存在的Id,也就是不能更新) //request.add(new IndexRequest(index,type).opType("create").id(map.remove("id").toString()).source(map));
request.add(new IndexRequest(index, type, String.valueOf(map.remove("id"))).source(map,XContentType.JSON));
restHighLevelClient.bulk(request);
}
}
