Spring boot + Elastic Search

1. Dependency 추가

  - build.gradle

compile("org.springframework.data:spring-data-elasticsearch")

2. Properties 추가

  - application.yml

spring:
  data:
    rest.base-path: /api/elastic # Context PATH
    elasticsearch:
      cluster-name: es  # Elasticsearch cluster name.
      cluster-nodes: xx.xx.xx.xx:9300 # Comma-separated list of cluster node addresses.      
      repositories.enabled: true # Whether to enable Elasticsearch repositories.

3. java-api로 해당부분 개발

  - 예시 

@Autowired
private ElasticsearchTemplate elasticsearchTemplate;

public List<Map> getTestList(List<Map> activeEventNotifyRequests){
   
   BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
   
   TermsQueryBuilder termsUidFilter = QueryBuilders.termsQuery("data", "1234");
   boolQuery.filter(termsUidFilter);
  
   NativeSearchQueryBuilder nativeSearchQueryBuilder = new NativeSearchQueryBuilder().withQuery(boolQuery)
         .withIndices("test-index")
         .withTypes("doc").withSort(SortBuilders.fieldSort("@timestamp").order(SortOrder.DESC));
   
   SearchQuery searchQuery = nativeSearchQueryBuilder.build();
   
   NMXEsUtil.printLogQuery(searchQuery, this.notifyIndex);
   
   List<Map> resultList = Lists.newArrayList();
   Page<Map> returnList = elasticsearchTemplate.queryForPage(searchQuery, Map.class);
   resultList.addAll(returnList.getContent());
   
   for(Map<String,Map> map:resultList) {
      System.out.println(map);
   }
   
   return resultList;
   
}
