3. Spring Data ElasticSearchアプリケーション

Spring Boot Spring Data Elasticsearchの例を開始しましょう。

3.1。プロジェクトのためのモデルを開発する

Book.java

package com.techfou.book.model;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName = "techfou", type = "books")
public class Book {

    @Id
    private String id;
    private String title;
    private String author;
    private String releaseDate;

    public Book() {
    }

    public Book(String id, String title, String author, String releaseDate) {
        this.id = id;
        this.title = title;
        this.author = author;
        this.releaseDate = releaseDate;
    }

   //getters and setters

    @Override
    public String toString() {
        return "Book{" +
                "id='" + id + '\'' +
                ", title='" + title + '\'' +
                ", author='" + author + '\'' +
                ", releaseDate='" + releaseDate + '\'' +
                '}';
    }
}

3.2。プロジェクトのためのElasticsearchリポジトリを開発する

BookRepository.java

package com.mkyong.book.repository;

import com.mkyong.book.model.Book;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

import java.util.List;

public interface BookRepository extends ElasticsearchRepository<Book, String> {

    Page<Book> findByAuthor(String author, Pageable pageable);

    List<Book> findByTitle(String title);

}

3.3。プロジェクトのサービスコンポーネントを開発する

BookService.java

package com.mkyong.book.service;

import com.mkyong.book.model.Book;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;

import java.util.List;

public interface BookService {

    Book save(Book book);

    void delete(Book book);

    Book findOne(String id);

    Iterable<Book> findAll();

    Page<Book> findByAuthor(String author, PageRequest pageRequest);

    List<Book> findByTitle(String title);

}

BookServiceImpl.java

package com.mkyong.book.service;

import com.mkyong.book.model.Book;
import com.mkyong.book.repository.BookRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookServiceImpl implements BookService {

    private BookRepository bookRepository;

    @Autowired
    public void setBookRepository(BookRepository bookRepository) {
        this.bookRepository = bookRepository;
    }


    public Book save(Book book) {
        return bookRepository.save(book);
    }

    public void delete(Book book) {
        bookRepository.delete(book);
    }

    public Book findOne(String id) {
        return bookRepository.findOne(id);
    }

    public Iterable<Book> findAll() {
        return bookRepository.findAll();
    }

    public Page<Book> findByAuthor(String author, PageRequest pageRequest) {
        return bookRepository.findByAuthor(author, pageRequest);
    }

    public List<Book> findByTitle(String title) {
        return bookRepository.findByTitle(title);
    }

}

3.4。 Elasticsearchプロパティを持つ `application.properties`を開発してください。

application.properties

elasticsearch.clustername = mkyong-cluster
elasticsearch.host = localhost
elasticsearch.port = 9300

#
# Home directory of the embedded Elasticsearch instance. Default to the
# current working directory.
#
#spring.data.elasticsearch.properties.path.home=target/elastic-embedded
#spring.data.elasticsearch.properties.transport.tcp.connect__timeout=60s

3.5。 Springブート構成を開発する。 `TransportClient`を介してElasticsearchクラスタに接続する

MkyongElasticsearchConfiguration.java

package com.mkyong;

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

import java.net.InetAddress;

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.mkyong.book.repository")
public class EsConfig {

    @Value("${elasticsearch.host}")
    private String EsHost;

    @Value("${elasticsearch.port}")
    private int EsPort;

    @Value("${elasticsearch.clustername}")
    private String EsClusterName;

    @Bean
    public Client client() throws Exception {

        Settings esSettings = Settings.settingsBuilder()
                .put("cluster.name", EsClusterName)
                .build();

       //https://www.elastic.co/guide/en/elasticsearch/guide/current/__transport__client__versus__node__client.html
        return TransportClient.builder()
                .settings(esSettings)
                .build()
                .addTransportAddress(
                  new InetSocketTransportAddress(InetAddress.getByName(EsHost), EsPort));
    }

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() throws Exception {
        return new ElasticsearchTemplate(client());
    }

   //Embedded Elasticsearch Server
   /** @Bean
    public ElasticsearchOperations elasticsearchTemplate() {
        return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
    }** /
}

4.テストアプリケーションの開発

私たちのコードをユニットテストするための1つのテストアプリケーションを開発しましょう。

BookServiceTest.java

package com.mkyong;

import com.mkyong.book.model.Book;
import com.mkyong.book.service.BookService;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.ArrayList;
import java.util.List;

import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.junit.Assert.** ;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class BookServiceTest {

    @Autowired
    private BookService bookService;

    @Autowired
    private ElasticsearchTemplate esTemplate;

    @Before
    public void before() {
        esTemplate.deleteIndex(Book.class);
        esTemplate.createIndex(Book.class);
        esTemplate.putMapping(Book.class);
        esTemplate.refresh(Book.class);
    }

    @Test
    public void testSave() {

        Book book = new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017");
        Book testBook = bookService.save(book);

        assertNotNull(testBook.getId());
        assertEquals(testBook.getTitle(), book.getTitle());
        assertEquals(testBook.getAuthor(), book.getAuthor());
        assertEquals(testBook.getReleaseDate(), book.getReleaseDate());

    }

    @Test
    public void testFindOne() {

        Book book = new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017");
        bookService.save(book);

        Book testBook = bookService.findOne(book.getId());

        assertNotNull(testBook.getId());
        assertEquals(testBook.getTitle(), book.getTitle());
        assertEquals(testBook.getAuthor(), book.getAuthor());
        assertEquals(testBook.getReleaseDate(), book.getReleaseDate());

    }

    @Test
    public void testFindByTitle() {

        Book book = new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017");
        bookService.save(book);

        List<Book> byTitle = bookService.findByTitle(book.getTitle());
        assertThat(byTitle.size(), is(1));
    }

    @Test
    public void testFindByAuthor() {

        List<Book> bookList = new ArrayList<>();

        bookList.add(new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017"));
        bookList.add(new Book("1002", "Apache Lucene Basics", "Rambabu Posa", "13-MAR-2017"));
        bookList.add(new Book("1003", "Apache Solr Basics", "Rambabu Posa", "21-MAR-2017"));
        bookList.add(new Book("1007", "Spring Data + ElasticSearch", "Rambabu Posa", "01-APR-2017"));
        bookList.add(new Book("1008", "Spring Boot + MongoDB", "Mkyong", "25-FEB-2017"));

        for (Book book : bookList) {
            bookService.save(book);
        }

        Page<Book> byAuthor = bookService.findByAuthor("Rambabu Posa", new PageRequest(0, 10));
        assertThat(byAuthor.getTotalElements(), is(4L));

        Page<Book> byAuthor2 = bookService.findByAuthor("Mkyong", new PageRequest(0, 10));
        assertThat(byAuthor2.getTotalElements(), is(1L));

    }

    @Test
    public void testDelete() {

        Book book = new Book("1001", "Elasticsearch Basics", "Rambabu Posa", "23-FEB-2017");
        bookService.save(book);
        bookService.delete(book);
        Book testBook = bookService.findOne(book.getId());
        assertNull(testBook);
    }

}
