Born To Simplify Development

Easy-Es is a powerfully enhanced toolkit of RestHighLevelClient for simplify development. This toolkit provides some efficient, useful, out-of-the-box features for ElasticSearch. By using Easy-Es, you can use MySQL syntax to complete Es queries. Use it can effectively save your development time.

Demand: Query all documents with title equals "Hi" and author equals "Guy"

// Use Easy-Es to complete the query with only 1 lines of code
List<Document> documents = documentMapper.selectList(EsWrappers.lambdaQuery(Document.class).eq(Document::getTitle, "Hi").eq(Document::getCreator, "Guy"));

// Query with RestHighLevelClient requires 11 lines of code, not including parsing JSON code
String indexName = "document";
        SearchRequest searchRequest = new SearchRequest(indexName);
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        TermQueryBuilder titleTerm = QueryBuilders.termQuery("title", "Hi");
        TermsQueryBuilder creatorTerm = QueryBuilders.termsQuery("creator", "Guy");
        boolQueryBuilder.must(titleTerm);
        boolQueryBuilder.must(creatorTerm);
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(boolQueryBuilder);
        searchRequest.source(searchSourceBuilder);
        try {
        SearchResponse searchResponse = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
        // Then parse the DocumentList from searchResponse in various ways, omitting these codes...
        } catch (IOException e) {
        e.printStackTrace();
        }

The above is just a simple query demonstration. The more complex the actual query scene, the better the effect, which can save 3-5 times the amount of code on average.

• Latest Version:

• Add Easy-Es dependency

  • Maven:

    <dependency>
      <groupId>org.dromara.easy-es</groupId>
      <artifactId>easy-es-boot-starter</artifactId>
      <version>Latest Version</version>
    </dependency>

  • Gradle

    compile group: 'org.dromara.easy-es', name: 'easy-es-boot-starter', version: 'Latest Version'

• Add mapper file extends BaseEsMapper interface

  public interface DocumentMapper extends BaseMapper<User> {
  }

• Use it

  LambdaEsQueryWrapper<Document> wrapper = new LambdaEsQueryWrapper<>();
  wrapper.eq(Document::getTitle,"Hello World")
         .eq(Document::getCreator,"Guy");
  List<Document> documentList = documentMapper.selectList();

  Easy-Es will execute the following Query:

  {"query":{"bool":{"must":[{"term":{"title":{"value":"Hello World","boost":1.0}}},{"term":{"creator":{"value":"Guy","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}}}

  The syntax of this query in MySQL is:

   SELECT * FROM document WHERE title = 'Hello World' AND creator = 'Guy'

This showcase is just a small part of Easy-Es features. If you want to learn more, please refer to the documentation.
