- 新建web工程
- 导入jar包
- 编写springmvc配置文件

- 编写web.xml

- 导入静态资源文件
- 建立包结构
- 创建pojo
商品实体类
package com.jd.pojo; public class Product { // 商品编号 private String pid; // 商品名称 private String name; // 商品分类名称 private String catalog_name; // 价格 private float price; // 商品描述 private String description; // 图片名称 private String picture; public String getPid() { return pid; } public void setPid(String pid) { this.pid = pid; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getCatalog_name() { return catalog_name; } public void setCatalog_name(String catalog_name) { this.catalog_name = catalog_name; } public float getPrice() { return price; } public void setPrice(float price) { this.price = price; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getPicture() { return picture; } public void setPicture(String picture) { this.picture = picture; } }
封装分页实体类
package com.jd.pojo; import java.util.List; public class ResultModel { // 商品列表 private List<Product> list; // 商品总数 private Long recordCount; // 总页数 private Long pageCount; // 当前页 private long curPage; public List<Product> getList() { return list; } public void setList(List<Product> list) { this.list = list; } public Long getRecordCount() { return recordCount; } public void setRecordCount(Long recordCount) { this.recordCount = recordCount; } public Long getPageCount() { return pageCount; } public void setPageCount(Long pageCount) { this.pageCount = pageCount; } public long getCurPage() { return curPage; } public void setCurPage(long curPage) { this.curPage = curPage; } }
- ProductMapper

- ProductService
package com.jd.service; import com.jd.pojo.Product; import com.jd.pojo.QueryVo; import com.jd.pojo.ResultModel; public interface ProductService { /** * 分页条件查询所有商品 * * @param solrQuery * @return * @throws Exception */ public ResultModel<Product> findAll(QueryVo queryVo) throws Exception; }
