一.简单的搜索功能
1：mapper.xml文件:
<?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.google.crm.dao.SearchItemDao">
<select id="getItemList" resultType="SearchItem">
SELECT
a.id,
a.title,
a.sell_point,
a.price,
a.image,
b. NAME category_name,
c.item_desc
FROM
tb_item a
LEFT JOIN tb_item_cat b ON a.cid = b.id
LEFT JOIN tb_item_desc c ON a.id = c.item_id
WHERE
a.`status` = 1
</select>
</mapper>
2：model模型创建 SearchItem.java
private String id;
private String title;
private String sell_point;
private long price;
private String image;
private String category_name;
private String item_desc;
3.dao接口:
public interface SearchItemDao {
List<SearchItem> getItemList();
}
4.service服务层：@Service
public class SearchItemService {
@Resource
private SearchItemDao searchItemDao;
public List<SearchItem> getItem(){
return this.searchItemDao.getItemList();
}
}
5.controller控制层：public String getsearchitem(Model model) {
List<SearchItem> searchItems = this.searchItemService.getItem();
if (searchItems != null) {
model.addAttribute("searchItems", searchItems);
return "searchItems";
} else {
return "init";
}
}
6.可视化层view:
<table border="1">
<tr align="center">
<td>id</td>
<td>标题</td>
<td>买点</td>
<td>价格</td>
<td>图片</td>
<td>分类</td>
<%-- <td>描述</td>--%>
</tr>
<c:forEach var="s" items="${searchItems }">
<tr align="center">
<td>${s.id }</td>
<td>${s.title }</td>
<td>${s.sell_point }</td>
<td>${s.price }</td>
<td>${s.image }</td>
<td>${s.category_name }</td>
<%-- <td>${s.item_desc }</td>--%>
</tr>
</c:forEach>
</table>
二.测试用例 把测试文档写到solr引擎上
127.0.0.1
打通windows和ubuntu下的solr引擎http://192.168.0.128:8080/solr/#/
使用ifconfig命令时，只返回lo这一项
解决方法：安装无线网卡即可
1. sudo lshw -numeric -class network
2. sudo route -nv
3. sudo dhclient -v
