如何使用SpringBoot与Elasticsearch进行集成实现搜索功能?

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

spring.data.elasticsearch.client.reactive.enabled=false
spring.elasticsearch.rest.uris=http://localhost:9200
spring.data.elasticsearch.repositories.enabled=true

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

@Document(indexName = "product")
public class Product {

    @Id
    private String id;
    private String name;
    private String description;

    // Getter and Setter methods
}

import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

public interface ProductRepository extends ElasticsearchRepository<Product, String> {
    // 可以在这里添加自定义的查询方法
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class ProductService {

    @Autowired
    private ProductRepository productRepository;

    // 添加一个方法来根据名称搜索产品
    public List<Product> searchByName(String name) {
        return productRepository.findByName(name);
    }
}

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

import java.util.List;

@RestController
@RequestMapping("/products")
public class ProductController {

    @Autowired
    private ProductService productService;

    @GetMapping("/search")
    public List<Product> search(@RequestParam String name) {
        return productService.searchByName(name);
    }
}

@Query("{\"match\": {\"name\": \"?0\"}}")
List<Product> findByCustomQuery(String name);

spring.elasticsearch.rest.uris=http://localhost:9200

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.RestClients;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;

@Configuration
public class ElasticsearchConfig {

    @Bean
    public ElasticsearchRestTemplate elasticsearchRestTemplate() {
        ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("localhost:9200")
                .build();
        return new ElasticsearchRestTemplate(RestClients.create(clientConfiguration).rest());
    }
}

QueryBuilder queryBuilder = QueryBuilders.boolQuery()
        .must(QueryBuilders.matchQuery("name", "example"))
        .filter(QueryBuilders.termQuery("status", "active"));
