门户首页功能是客户可以在这页面进行查看书籍
门户首页功能所需的的dao，web及辅助类
dao
bookDao 中新增两个门户新书上架，门户热销书籍的方法
// 门户新书上架的书籍public List<Book> news(Book book,PageBean pageBean) throws Exception{String sql = "select * from t_easyui_book where state =2 order by deploytime desc limit 10";return super.executeQuery(sql, pageBean, Book.class);}// 门户热销书籍public List<Book> hots(Book book,PageBean pageBean) throws Exception{String sql = "select * from t_easyui_book where state =2 order by sales desc limit 12";return super.executeQuery(sql, pageBean, Book.class);}
web
bookAction 中新增newss，hotss两个方法
public String newss(HttpServletRequest request, HttpServletResponse response) {try {List<Book> newsBook = this.bookDao.news(null, null);ResponseUtil.writeJson(response,Result.ok(newsBook));} catch (Exception e) {e.printStackTrace();}return null;}public String hotss(HttpServletRequest request, HttpServletResponse response) {try {List<Book> hots = this.bookDao.hots(null, null);ResponseUtil.writeJson(response,Result.ok(hots));} catch (Exception e) {e.printStackTrace();}return null;}
辅助类
Result 响应结果集
package com.tang.util;
/*** （响应结果集）* @author Administrator** @param <T>*/
public class Result<T> {private int code;private String msg;private T data;public static Result SUCCESS = new Result<>(200,"操作成功");public static <T> Result ok(T data) {return new Result(data);}public int getCode() {return code;}public void setCode(int code) {this.code = code;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public T getData() {return data;}public void setData(T data) {this.data = data;}private Result(int code, String msg) {super();this.code = code;this.msg = msg;}private Result() {super();}private Result(T data) {super();this.data = data;}}首页界面
