Elasticsearch结合java实现组合查询（模糊，区间，精确，分页）

具体实现看下图：

导入es的jar

		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        </dependency>

创建Repository

public interface UserRepository extends ElasticsearchRepository<实体类名称,id类型> {


}

service层进行组合查询

@Autowired
    private LogRepository logRepository;

    @Override
    public Map LogSearch(Integer page, Integer size, User user) {
        Integer offset = (page - 1);
        BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();
        if (StringUtils.isNotBlank(user.getName)) {  
            queryBuilder.must(QueryBuilders.matchPhraseQuery("name", user.getName));
        }
        if (StringUtils.isNotBlank(user.getStarttime()) || StringUtils.isNotBlank(user.getEndtime())) {   //操作时间
            //区间查询
            queryBuilder.must(QueryBuilders.rangeQuery("timestamp.keyword").gte(user.getStarttime()).lte(user.getEndtime()));
        }
        if (StringUtils.isNotBlank(user.getFraction())) {
	        //精确查询
            queryBuilder.must(QueryBuilders.termQuery("fraction", user.getFraction));
        }
        if (StringUtils.isNotBlank(user.getUsername())) {
            //模糊查询
            queryBuilder.must(QueryBuilders.matchPhraseQuery("userName", user.getUsername()));
        }
        SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withIndices("索引名称").withTypes("索引类型")
                .withQuery(queryBuilder)
                .withPageable(new PageRequest(offset, size)) //分页
                .withSort(SortBuilders.fieldSort("@timestamp").order(SortOrder.DESC))
                .build();
        Page<User> search = logRepository.search(searchQuery);
        int totalElements = (int) search.getTotalElements(); //获取总条数
        List<User> content = search.getContent();
        Map<String, Object> maps = new HashMap<>();
        maps.put("page", page); 
        maps.put("totalElements", totalElements); 
        maps.put("size", size);
        maps.put("list", content);
        return maps;
    }
