二 、java通过Solrj操作solr

1. 创建maven工程 (pom.xml)

<project xmlns="http://maven.apache.org/POM/4.0.0"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0   http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <groupId>com.jiazf.demo</groupId>
      <artifactId>solrdemo</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <dependencies>
            <!--   https://mvnrepository.com/artifact/org.apache.solr/solr-solrj -->
            <dependency>
                  <groupId>org.apache.solr</groupId>
                  <artifactId>solr-solrj</artifactId>
                  <version>4.10.4</version>
            </dependency>
            <!-- https://mvnrepository.com/artifact/junit/junit   -->
            <dependency>
                  <groupId>junit</groupId>
                  <artifactId>junit</artifactId>
                  <version>4.12</version>
                  <scope>test</scope>
            </dependency>
            <!--   https://mvnrepository.com/artifact/commons-logging/commons-logging -->
            <dependency>
                  <groupId>commons-logging</groupId>
                  <artifactId>commons-logging</artifactId>
                  <version>1.2</version>
            </dependency>
      </dependencies>
</project>

2. 创建java测试类

package mytest;

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.impl.HttpSolrServer;
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.junit.Test;

import java.io.IOException;
import java.util.List;
import java.util.Map;

public class SolrjTest {
    //创建一个连接
    SolrServer solrServer = new HttpSolrServer("http://192.168.153.22:8080/solr");

    @Test
    /**
     * 增加操作
     */
    public void addItem() throws IOException, SolrServerException {

        //创建一个文档对象
        SolrInputDocument document = new SolrInputDocument();
        document.addField("id", "test001");
        document.addField("item_title", "测试title");
        document.addField("item_sell_point", "测试");
        document.addField("item_price", "11111");
        document.addField("item_image", "111111");
        document.addField("item_category_name", "111111");

        //将item添加到solr的服务器中
        solrServer.add(document);
        solrServer.commit();
    }

    @Test
    /**
     * 删除操作
     */
    public void deleteItem() throws IOException, SolrServerException {
        solrServer.deleteByQuery("id:test001");
        solrServer.commit();
    }

    @Test
    /**
     * 查询 "三星" 关键字
     */
    public void paginatedQuery() throws Exception {
        int page = 8;
        int size = 5;
        // 创建一个查询对象
        SolrQuery query = new SolrQuery();
        // 设置查询条件
        query.setQuery("三星");
        //设置开始条目数字
        query.setStart((page - 1) * size);
        //设置每页显示多少条记录
        query.setRows(size);
        //设置是否使用高亮
        query.setHighlight(true);
        //高亮的前置字符串
        query.setHighlightSimplePre("<span style='color:red; font-weight:bold'>");
        //高亮的后置字符串
        query.setHighlightSimplePost("</span>");
        //设置默认字段用于搜索
        query.set("df", "item_title");
        //设置添加高亮的字段
        query.addHighlightField("item_title");
        // 根据查询条件查询索引库
        QueryResponse queryResponse = solrServer.query(query);
        // 取查询结果
        SolrDocumentList solrDocumentList = queryResponse.getResults();
        // 取查询结果总数量
        System.out.println(solrDocumentList.getNumFound());
        // 取高亮显示
        Map<String, Map<String, List<String>>> highlighting = queryResponse.getHighlighting();
        // 取商品列表
        for (SolrDocument solrDocument : solrDocumentList) {
            System.out.println(solrDocument.get("id"));
            // 取高亮显示的结果
            List<String> list = highlighting.get(solrDocument.get("id")).get("item_title");
            String title = "";
            if (list != null && list.size() > 0) {
                title = list.get(0);
            } else {
                title = (String) solrDocument.get("item_title");
            }
            System.out.println(title);
            System.out.println(solrDocument.get("item_image"));
            System.out.println(solrDocument.get("item_price"));
            System.out.println(solrDocument.get("item_sell_point"));
            System.out.println(solrDocument.get("item_category_name"));
            System.out.println("=======================================");
        }
    }
}
