接上一篇内容​​一文读懂SpringBoot整合Elasticsearch（一）​​

下面是完整的代码示例，可以参考实现自己的应用程序。

1. pom.xml文件

phpCopy code<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

1. application.properties文件

kotlinCopy codespring.data.elasticsearch.cluster-nodes=localhost:9300
spring.data.elasticsearch.cluster-name=my-application

1. Book实体类

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

@Document(indexName = "book", type = "novel")
public class Book {
    @Id
    private String id;
    private String title;
    private String author;

    // getter and setter methods
}

1. BookRepository接口

kotlinCopy codeimport org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

public interface BookRepository extends ElasticsearchRepository<Book, String> {
}

1. BookController类

lessCopy codeimport org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/book")
public class BookController {
    @Autowired
    private BookRepository bookRepository;

    @PostMapping("/")
    public Book addBook(@RequestBody Book book) {
        return bookRepository.save(book);
    }

    @GetMapping("/{id}")
    public Book getBook(@PathVariable String id) {
        return bookRepository.findById(id).orElse(null);
    }

    @GetMapping("/")
    public List<Book> searchBook(@RequestParam String keyword) {
        return bookRepository.findByTitleOrAuthor(keyword, keyword);
    }
}

1. 测试代码

javaCopy code@RunWith(SpringRunner.class)
@SpringBootTest
public class BookControllerTest {
    @Autowired
    private BookController bookController;

    @Test
    public void addBook() {
        Book book = new Book();
        book.setTitle("The Lord of the Rings");
        book.setAuthor("J.R.R. Tolkien");
        bookController.addBook(book);
    }

    @Test
    public void getBook() {
        Book book = bookController.getBook("1");
        Assert.assertNotNull(book);
        Assert.assertEquals("The Lord of the Rings", book.getTitle());
        Assert.assertEquals("J.R.R. Tolkien", book.getAuthor());
    }

    @Test
    public void searchBook() {
        List<Book> bookList = bookController.searchBook("Rings");
        Assert.assertTrue(bookList.size() > 0);
    }
}

以上是一个简单的Spring Boot整合Elasticsearch的示例，供读者参考。
