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

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 {
/**
*
*
*<p>Description:在Solr中获取数据并转成Json</p>
*
* @author：SongJia
*
* @date: 2017-8-9下午7:54:23

*/
@RequestMapping("/getSolrJson")
@ResponseBody
public String getJosnFromSolr(String parameter){
System.out.println(parameter);

}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public List<T> getData() {
return data;
}
public void setData(List<T> data) {
this.data = data;
}
}

var parameter = $("#parameter").val();
$("#article").empty();
$.ajax({
