Solr案列：从数据库中获取数据添加到Solr索引库中，在Solr索引库中搜索获取数据在页面展示_solr file upload使用

作者：weixin_40725706 | 2024-07-05 03:01:15

踩

solr file upload使用

一：案列需求：

1）使用技术 springMVC+Spring+Mybatis+solrJ

2）将 mysql 中的 tb_item 表中的部分业务数据导入到 solr 的索引库中

3）提供一个搜索页面，在搜索页面中完成数据搜索

二：使用软件：IDEA。使用MAVEN管理项目。

先搭建环境

三：实现功能1：从数据库中获取数据添加到Solr索引库中:数据为商品数据

1.pojo-->TbItem


package com.bjsxt.pojo;
 
import java.io.Serializable;
import java.util.Date;
 
public class TbItem implements Serializable {
    private Long id;
 
    private String title;
 
    private String sell_Point;
 
    private Long price;
 
    private Integer num;
 
    private String barcode;
 
    private String image;
 
    private Long cid;
 
    private Byte status;
 
    private Date created;
 
    private Date updated;
 
    public Long getId() {
        return id;
    }
 
    public void setId(Long id) {
        this.id = id;
    }
 
    public String getTitle() {
        return title;
    }
 
    public void setTitle(String title) {
        this.title = title == null ? null : title.trim();
    }
 
 
    public String getSell_Point() {

	}
 
	public void setSell_Point(String sell_Point) {

	}
 
	public Long getPrice() {
        return price;
    }
 
    public void setPrice(Long price) {
        this.price = price;
    }
 
    public Integer getNum() {
        return num;
    }
 
    public void setNum(Integer num) {
        this.num = num;
    }
 
    public String getBarcode() {
        return barcode;
    }
 
    public void setBarcode(String barcode) {
        this.barcode = barcode == null ? null : barcode.trim();
    }
 
    public String getImage() {
        return image;
    }
 
    public void setImage(String image) {
        this.image = image == null ? null : image.trim();
    }
 
    public Long getCid() {
        return cid;
    }
 
    public void setCid(Long cid) {
        this.cid = cid;
    }
 
    public Byte getStatus() {
        return status;
    }
 
    public void setStatus(Byte status) {
        this.status = status;
    }
 
    public Date getCreated() {
        return created;
    }
 
    public void setCreated(Date created) {
        this.created = created;
    }
 
    public Date getUpdated() {
        return updated;
    }
 
    public void setUpdated(Date updated) {
        this.updated = updated;
    }
}

2.mapper-->ItemMapper


package com.bjsxt.mapper;
 
import com.bjsxt.pojo.TbItem;
 
import java.util.List;
 
public interface ItemMapper {
 
    List<TbItem> findAll();
}

mapper-->ItemMapper.xml


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.bjsxt.mapper.ItemMapper">
    <select id="findAll" resultType="com.bjsxt.pojo.TbItem">
        select *  from tb_item
    </select>
</mapper>

3.service-->ImportItemService----ImportItemServiceImpl


package com.bjsxt.service;
 
import com.bjsxt.pojo.TbItem;
 
import java.util.List;
 
public interface ImportItemService {
 
    void importItem();
}


package com.bjsxt.service.impl;
 
import com.bjsxt.mapper.ItemMapper;
import com.bjsxt.pojo.TbItem;
import com.bjsxt.service.ImportItemService;
import org.apache.solr.client.solrj.impl.CloudSolrServer;
import org.apache.solr.common.SolrInputDocument;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import java.util.ArrayList;
import java.util.List;
 
/**
 * 从数据库中获取数据导入索引库
 */
@Service
public class ImportItemServiceImpl implements ImportItemService {
    @Autowired
    private ItemMapper itemMapper;
    @Autowired
    private CloudSolrServer cloudSolrServer;
    @Override
    public void importItem() {
        try {
        //查询数据库所以数据
        List<TbItem> list = this.itemMapper.findAll();
        //创建文档集合模型
        List<SolrInputDocument> result=new ArrayList<>();
        //遍历数据并创建索引库文档导入文档中
        for(TbItem item:list){
            //创建文档
            SolrInputDocument document=new SolrInputDocument();
            //讲数据库中部分数据放入文档中
            document.addField("id",item.getId()+"");
            document.addField("item_title",item.getTitle());
            document.addField("item_sell_point",item.getSell_Point());
            document.addField("item_price",item.getPrice());
            document.addField("item_image",item.getImage());
            //添加文档数据到文档模型中
            result.add(document);
        }
        this.cloudSolrServer.add(result);
        this.cloudSolrServer.commit();
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

3.Controller-->ImportDataController


package com.bjsxt.web.controller;
 
import com.bjsxt.service.ImportItemService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
 
/**
 * 导入商品数据Controller
 */
@Controller
@RequestMapping("/import")
public class ImportDataController {
    @Autowired
    private ImportItemService importItemService;
    @RequestMapping("/importData")
    public String importData(){
        this.importItemService.importItem();
        return "ok";
    }
}

4.结果如图：

四：实现功能2：在Solr索引库中搜索获取数据在页面展示

1.pojo-->PageResult


package com.bjsxt.pojo;
 
import java.io.Serializable;
import java.util.List;
 
public class PageResult implements Serializable {
 
    private List<TbItem> result;//结果集
 
    private Integer indexPage;//当前页
 
    private Long totalPage;//总页数
 
    private Long totalNum;//总条数
 
    public List<TbItem> getResult() {
        return result;
    }
 
    public void setResult(List<TbItem> result) {
        this.result = result;
    }
 
    public Integer getIndexPage() {
        return indexPage;
    }
 
    public void setIndexPage(Integer indexPage) {
        this.indexPage = indexPage;
    }
 
    public Long getTotalPage() {
        return totalPage;
    }
 
    public void setTotalPage(Long totalPage) {
        this.totalPage = totalPage;
    }
 
    public Long getTotalNum() {
        return totalNum;
    }
 
    public void setTotalNum(Long totalNum) {
        this.totalNum = totalNum;
    }
}

2.dao-->SolrSearchItemDao----SolrSearchItemDaoImpl


package com.bjsxt.dao;
 
import com.bjsxt.pojo.PageResult;
import org.apache.solr.client.solrj.SolrQuery;
 
public interface SolrSearchItemDao {

            //创建接收页面对象
            PageResult page = new PageResult();
            //3.1.页面获得总条数

                    item.setImage((String)var.get("item_image"));
                    //由于对搜索关键字item_title设为高亮：所以需要对item_title判断是否为关键字，
                    List<String> h = hl.get(var.get("id")).get("item_title");
                    String title="";//设置变量title用于代替item_title
