Spring boot ES文档搜索

好的，您可以使用Spring Boot集成Elasticsearch来实现文档搜索。首先，您需要在pom.xml文件中添加Elasticsearch和Spring Data Elasticsearch的依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>7.5.2</version>
</dependency>

然后，您需要配置Elasticsearch客户端：

@Configuration
public class ElasticsearchConfig {

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

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

    @Bean
    public RestHighLevelClient elasticsearchClient() {
        return new RestHighLevelClient(RestClient.builder(new HttpHost(host, port)));
    }
}

接下来，您需要定义一个Elasticsearch文档实体类，并使用`@Document`注解将其与Elasticsearch中的索引关联起来：

@Document(indexName = "my_index", type = "my_type")
public class MyDocument {
    @Id
    private String id;
    private String title;
    private String content;
    // getters and setters
}

然后，您可以使用`ElasticsearchRepository`接口提供的方法来实现搜索：

public interface MyDocumentRepository extends ElasticsearchRepository<MyDocument, String> {
    List<MyDocument> findByTitleOrContent(String title, String content);
}

最后，您可以在Spring Boot应用程序中使用`MyDocumentRepository`来搜索文档：

@Autowired
private MyDocumentRepository repository;

public void searchDocuments(String query) {
    List<MyDocument> documents = repository.findByTitleOrContent(query, query);
    // do something with the documents
}
