1 项目需求
1.可以根据关键字搜索商品
2.可以根据商品的分类和价格过滤搜索结果
3.可以根据价格排序
4.可以实现基本的分页功能
2 界面效果
3 项目环境搭建
1.创建一个动态的web工程
2.导入springmvc相关的jar包
3.导入solrJ的jar包和依赖包
4.导入solr/example/lib/ext下的jar包
5.配置springmvc.xml配置文件
6.配置web.xml配置文件
7.配置图片文件的虚拟路径
8.拷贝样式文件到项目中
springmvc.xml配置文件

web.xml配置文件

虚拟路径的配置
4 前端实现
1. 前端需要提供后端查询需要的参数 ：
关键词：queryString
商品分类：catalog_name 【隐藏域】
商品价格：price 【隐藏域】
价格排序：sort 【隐藏域】
分页所需的当前页：currentPage 【隐藏域】
2.后端需要返回给前端页面的信息：
商品的集合：ProductModelList
分页相关的数据：比如currentPage , totalCount,pageCount
