springboot整合es实现模糊查询java代码

好的，这是一个示例代码：

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。
