This article shows you how to configure the Solr index library. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Spring integrates Solr

Spring configuration:

Java code manipulates the Solr index library:

Package cn.xing.test;import java.util.ArrayList;import java.util.List;import java.util.Map;import org.apache.solr.client.solrj.SolrQuery;import org.apache.solr.client.solrj.SolrServer;import org.apache.solr.client.solrj.SolrServerException;import org.apache.solr.client.solrj.response.QueryResponse;import org.apache.solr.common.SolrDocument;import org.apache.solr.common.SolrDocumentList;import org.apache.solr.common.SolrInputDocument;import org.springframework.beans.factory.annotation.Autowired Import org.springframework.stereotype.Service;import cn.xing.pojo.SearchItem;import cn.xing.pojo.SearchResult;/** * operate solr index database * * @ author Xing * * / @ Servicepublic class Operation {@ Autowired private SolrServer solrServer / / the configured httpSolrServer / * imports all goods into the index database, and the commodity object SearchItem must be the same as the business domain field and type configured by solr * / public void imprtSolrItem () {try {List list = new ArrayList () List.add (new SearchItem ("1", "Hubei", "Yellow Crane Tower", 12, "image1", "provinces and cities"); list.add (new SearchItem ("2", "Henan", "Kaifeng", 12, "image2", "provinces and cities")) List.add (new SearchItem ("3", "3", "3", 12, "image2", "222")); / / put list into the index library for (SearchItem searchItem: list) {SolrInputDocument doc = new SolrInputDocument () Doc.addField ("id", searchItem.getId ()); doc.addField ("item_title", searchItem.getTitle ()); doc.addField ("item_sell_point", searchItem.getSell_point ()) Doc.addField ("item_price", searchItem.getPrice ()); doc.addField ("item_image", searchItem.getImage ()); doc.addField ("item_category_name", searchItem.getCategory_name ()); solrServer.add (doc) } solrServer.commit (); System.out.println ("data imported successfully");} catch (Exception e) {e.printStackTrace () }} / / according to the query condition SolrQuery, query the index library public List querySolr (SolrQuery query) throws SolrServerException {/ / query the index library QueryResponse queryResponse = solrServer.query (query); SolrDocumentList results = queryResponse.getResults () / / take out the total number of records long num = results.getNumFound (); System.out.println ("number of data entries of query results:" + num); / / take out the product list, highlight the keywords / / Map Map highlighting = queryResponse.getHighlighting (); List itemList = new ArrayList () For (SolrDocument solrDocument: results) {SearchItem item = new SearchItem (); item.setId ((String) solrDocument.get ("id")); item.setCategory_name ((String) solrDocument.get ("item_category_name")); item.setImage ((String) solrDocument.get ("item_image")) Item.setPrice ((long) solrDocument.get ("item_price")); item.setSell_point ((String) solrDocument.get ("item_sell_point")); / / highlight result, item title List list = highlighting.get (solrDocument.get ("id")) .get ("item_title") If (list! = null & & list.size () > 0) {item.setTitle (list.get (0)); / / get the title} else {item.setTitle ((String) solrDocument.get ("item_title")) } itemList.add (item);} return itemList;} / * search the solr index database for items and page them based on keywords. * / public SearchResult search (String keyword, int page, int rows) throws Exception {/ / set query condition, call querySolr () method to query SolrQuery query = new SolrQuery (); query.setQuery (keyword); / / set query condition if (page 0) totalpages++; rs.setTotalPages ((long) * totalpages) * / return rs;}}

Paging query data encapsulation:

Package cn.xing.pojo;import java.io.Serializable;import java.util.List;/** * results of search for goods. The encapsulation of the data needed by the page. * * @ author Xing * * / public class SearchResult implements Serializable {private Long totalPages; private Integer recourdCount; private List itemList;}

Pojo corresponding to Solr data:

Package cn.xing.pojo;import java.io.Serializable;import org.apache.commons.lang3.StringUtils;public class SearchItem implements Serializable {@ Override public String toString () {return "SearchItem [id=" + id + ", title=" + title + ", sell_point=" + sell_point + ", price=" + price + ", image=" + image + ", category_name=" + category_name + "]" } / / the type and the type configured in schema.xml in solr's Chinese parser must be the same as private String id; private String title; private String sell_point; private long price; private String image; private String category_name / / the search results page displays an image public String [] getImages () {String image2 = this.getImage (); if (StringUtils.isNotBlank (image2)) {String [] imagesArr = image2.split (","); return imagesArr;} return null } public String getId () {return id;} public void setId (String id) {this.id = id;}}

Java test code:

Package cn.xing.test;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.xing.pojo.SearchItem;import cn.xing.pojo.SearchResult;public class test {public static void main (String [] args) throws Exception {ApplicationContext ac = new ClassPathXmlApplicationContext ("classpath:applicationContext.xml"); Operation operation = ac.getBean (Operation.class) / / Import data operation.imprtSolrItem (); / / SearchResult search = operation.search ("obviously", 1, 1); SearchResult search = operation.search ("3", 1, 10); List itemList = search.getItemList () For (SearchItem searchItem: itemList) {System.out.println (searchItem);} the above content is [Learning Notes] how to configure the Solr index library.
