ruoyi在springboot项目中切换或添加es做搜索
在RuoYi项目中切换或添加Elasticsearch作为搜索引擎,你需要进行以下步骤:
- 添加Elasticsearch依赖到Spring Boot项目中的
pom.xml
文件:
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.10.2</version>
</dependency>
- 配置Elasticsearch客户端,在
application.yml
中添加Elasticsearch相关配置:
spring:
elasticsearch:
rest:
uris: "http://localhost:9200"
- 创建Elasticsearch配置类,配置RestHighLevelClient:
@Configuration
public class ElasticsearchConfig {
@Value("${spring.elasticsearch.rest.uris}")
private String[] esHosts;
@Bean
public RestHighLevelClient elasticsearchClient() {
RestClientBuilder builder = RestClient.builder(esHosts);
return new RestHighLevelClient(builder);
}
}
- 创建Elasticsearch操作服务,进行索引创建、文档添加、搜索等操作:
@Service
public class ElasticsearchService {
@Autowired
private RestHighLevelClient client;
public boolean createIndex(String index) throws IOException {
CreateIndexRequest request = new CreateIndexRequest(index);
CreateIndexResponse response = client.indices().create(request, RequestOptions.DEFAULT);
return response.isAcknowledged();
}
public boolean addDocument(String index, String id, Object document) throws IOException {
IndexRequest request = new IndexRequest(index).id(id).source(JSON.toJSONString(document), XContentType.JSON);
IndexResponse response = client.index(request, RequestOptions.DEFAULT);
return response.getResult() == DocWriteResponse.Result.CREATED;
}
public SearchResponse search(String index, SearchRequest searchRequest) throws IOException {
return client.search(searchRequest, RequestOptions.DEFAULT);
}
// 更多Elasticsearch操作...
}
- 在RuoYi的相关模块中使用ElasticsearchService进行搜索和索引操作。
确保Elasticsearch服务器正在运行,并且相应的端口(默认9200)未被防火墙阻挡。
以上步骤提供了一个简单的示例,实际应用中可能需要根据项目需求进行更复杂的配置和服务编写。
