mysql仿百度搜索高亮_Solr(五)Solr实现简单的类似百度搜索高亮功能-2代码

Solr高亮

一 在配置文件中，配置支持Ik分词器的Field

修改文件：

cd /usr/local/tomcat/apache-tomcat-8.5.13/solr_home/Test/conf/

vi managed-schema

红色部分是支持Ik分词器高亮显示的Field

二 配置完成之后，重启Tomcat，编写代码进行测试，对于环境搭建本文不做过多赘述。

1 与Solr服务器连接获取数据的类SolrRepository

package com.sgcc.ge.solr;

import java.io.IOException;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import org.apache.solr.client.solrj.SolrQuery;

import org.apache.solr.client.solrj.SolrServerException;

import org.apache.solr.client.solrj.impl.HttpSolrClient;

import org.apache.solr.client.solrj.response.QueryResponse;

import org.apache.solr.common.SolrDocument;

import org.apache.solr.common.SolrDocumentList;

import org.springframework.stereotype.Service;

import com.sgcc.ge.article.bean.ArticleBean;

@Service("solrRepository")

public class SolrRepository {

/**

*

*

*

Description:Get data from solr core return Json

*

* @author：SongJia

*

* @date: 2017-8-9下午7:56:04

*

* @param tag

* @return

* @throws SolrServerException

* @throws IOException

*/

public List getSolrDataJson(String tag) throws SolrServerException, IOException{

HttpSolrClient client = new HttpSolrClient("http://192.168.3.208:8080/solr/Test");

QueryResponse resp=null;

SolrQuery query = new SolrQuery("art_title:" +"*"+tag+"*" + " or art_tag:" + "*"+tag+"*"+" or art_abstract:"+"*"+tag+"*");

query.setHighlight(true);

query.addHighlightField("art_title");

query.addHighlightField("art_tag");

query.addHighlightField("art_abstract");

query.setHighlightSimplePre("");

query.setHighlightSimplePost("");

query.setHighlightFragsize(300);

resp = client.query(query);

SolrDocumentList solrDocumentList = resp.getResults();

//获取高亮的字段

Map>> highlighting = resp.getHighlighting();

List list =new ArrayList();

//List result = new ArrayList();

//取出数据并封装到Map里面

for (int i = 0; i < solrDocumentList.size(); i++) {

SolrDocument sd = solrDocumentList.get(i);

ArticleBean bean = new ArticleBean();

String art_title = (String) sd.getFieldValue("art_title");

String id = (String) sd.getFieldValue("id");

String art_tag = (String) sd.getFieldValue("art_tag");

String art_abstract = (String) sd.getFieldValue("art_abstract");

String art_time = (String) sd.getFieldValue("art_time");

bean.setArtTag(art_tag);

bean.setArtTime(art_time);

bean.setArtTitle(art_title);

bean.setArtAbstract(art_abstract);

Iterator>>> it = highlighting.entrySet().iterator();

while (it.hasNext()) {

Map.Entry>> entry = it.next();

String key = entry.getKey();

Map> value = entry.getValue();

if(key==id||key.equals(id)){

for (Map.Entry> inentry : value.entrySet()) {

String keyin = inentry.getKey();

List valuein = inentry.getValue();

if(keyin=="art_abstract"||keyin.equals("art_abstract")){

bean.setArtAbstract(valuein.get(0));

}else if(keyin=="art_tag"||keyin.equals("art_tag")){

bean.setArtTag(valuein.get(0));

}else if(keyin=="art_title"||keyin.equals("art_title")){

bean.setArtTitle(valuein.get(0));

}

}

}

}

list.add(bean);

}

return list;

}

}

2 控制器类ArticleController

package com.sgcc.ge.article;

import java.util.List;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import com.google.gson.Gson;

import com.google.gson.reflect.TypeToken;

import com.sgcc.ge.article.bean.ArticleBean;

import com.sgcc.ge.article.bean.MessageBean;

import com.sgcc.ge.solr.SolrRepository;

@Controller

@RequestMapping("/article")

public class ArticleController {

/**

*

*

*

Description:在Solr中获取数据并转成Json

*

* @author：SongJia

*

* @date: 2017-8-9下午7:54:23

*

* @param parameter

* @return

*/

@RequestMapping("/getSolrJson")

@ResponseBody

public String getJosnFromSolr(String parameter){

System.out.println(parameter);

Gson gson = new Gson();

String json="";

SolrRepository queryResult = new SolrRepository();

MessageBean bean = new MessageBean();

try {

List solrDataJson = queryResult.getSolrDataJson(parameter);

bean.setCode("0");

bean.setCode("Success");

bean.setData(solrDataJson);

json = gson.toJson(bean,new TypeToken>() { }.getType());

} catch (Exception e) {

bean.setCode("1");

bean.setCode("Failed");

json = gson.toJson(bean,new TypeToken>() { }.getType());

}

return json;

}

}

3 文章实体类ArticleBean

package com.sgcc.ge.article.bean;

public class ArticleBean {

private String artId;

private String artTitle;

private String artContent;

private String artTag;

private String artTime;

private String artAbstract;

public String getArtAbstract() {

return artAbstract;

}

public void setArtAbstract(String artAbstract) {

this.artAbstract = artAbstract;

}

public String getArtId() {

return artId;

}

public void setArtId(String artId) {

this.artId = artId;

}

public String getArtTitle() {

return artTitle;

}

public void setArtTitle(String artTitle) {

this.artTitle = artTitle;

}

public String getArtContent() {

return artContent;

}

public void setArtContent(String artContent) {

this.artContent = artContent;

}

public String getArtTag() {

return artTag;

}

public void setArtTag(String artTag) {

this.artTag = artTag;

}

public String getArtTime() {

return artTime;

}

public void setArtTime(String artTime) {

this.artTime = artTime;

}

}

4 返回给客户端格式化数据的消息类MessageBean

package com.sgcc.ge.article.bean;

import java.util.List;

public class MessageBean {

private String code;

private String message;

private List data;

public String getCode() {

return code;

}

public void setCode(String code) {

this.code = code;

}

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public List getData() {

return data;

}

public void setData(List data) {

this.data = data;

}

}

5 页面代码

function getData(){

var parameter = $("#parameter").val();

$("#article").empty();

$.ajax({

type: "POST",

data: {parameter:parameter},

url: "http://localhost:9000/ene/global_energy_run_analysis/rest/article/getSolrJson",

success: function(data){

var html="";

var obj =eval('('+data+')');

for(var i=0;i

var artTitle=obj.data[i].artTitle;

var artTag=obj.data[i].artTag;

var artTime=obj.data[i].artTime;

var artAbstract=obj.data[i].artAbstract;

html+="

• 文章标题："+artTitle+"

• 文章标签："+artTag+"

• 文章摘要："+artAbstract+"

• 文章时间："+artTime+"

";

html+="

• ********************************************************************

";

}

$("#article").append(html);

},

error:function(msg){

}

});

}
