好的,这是一个示例代码:
```java
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.index.query.QueryStringQueryBuilder;
import org.elasticsearch.search.builder.SearchSourceBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.data.elasticsearch.core.query.NativeSearchQuery;
import org.springframework.data.elasticsearch.core.query.NativeSearchQueryBuilder;
import org.springframework.stereotype.Service;
@Service
public class ElasticsearchService {
@Autowired
private ElasticsearchRestTemplate elasticsearchRestTemplate;
public List<YourEntity> search(String keyword) {
QueryStringQueryBuilder queryStringQueryBuilder = QueryBuilders.queryStringQuery(keyword);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(queryStringQueryBuilder);
NativeSearchQuery nativeSearchQuery = new NativeSearchQueryBuilder()
.withQuery(queryStringQueryBuilder)
.build();
return elasticsearchRestTemplate.queryForList(nativeSearchQuery, YourEntity.class);
}
}
```
其中,`YourEntity` 是你要查询的实体类,`keyword` 是你要查询的关键词。这个示例代码使用了 `ElasticsearchRestTemplate` 来操作 Elasticsearch,使用了 `QueryBuilders.queryStringQuery()` 方法来实现模糊查询。
