spring-data-elasticsearch 字段如何驼峰转下划线,并实现ES查询

spring-data-elasticsearch 字段如何驼峰转下划线

使用spring-data-elasticsearch,但是想在es中存储的时候使用下划线。

解决:实体中采用@Field(name = "test_id") 注解;

例如:

 ES查询:

import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
@Component
public class EsTaskJob {
    @Autowired
    private ElasticsearchRestTemplate elasticsearchRestTemplate;

  // 周期线程池
private final ScheduledExecutorService scheduledExecutorService = newScheduledThreadPool(16);
  // 执行一次
public void doStart() { scheduledExecutorService.schedule(new Runnable() { @Override public void run() { try { doTask(req); } catch (RuntimeException e) { e.printStackTrace(); } } }, 0, TimeUnit.SECONDS); } private void doTask(AssetRetrievalTaskReq req) {
     // 查询条件 BoolQueryBuilder boolQueryBuilder
= QueryBuilders.boolQuery(); boolQueryBuilder.must(QueryBuilders.matchQuery("be_app_name", "open")); // 查询
      SearchHits
<EsHttpReq> searchHitReqs = elasticsearchRestTemplate.search(query, EsHttpReq.class, IndexCoordinates.of("app_req")); if (searchHitReqs != null && searchHitReqs.getSearchHits().size() > 0) {
        // 读取返回内容
        for (org.springframework.data.elasticsearch.core.SearchHit<EsHttpReq> searchHit : searchHitReqs) { EsHttpReq esHttpReq = searchHit.getContent(); } } } }
