近期在做一个课程设计。在线小说站点的设计,下面是课题要求。须要项目练手的童鞋能够试试身手。
因为近期新学了JavaEE,所以採用了jsp+servlet来写,前端部分用了少量的js和jQuery处理。数据库用了mysql。开发平台是myeclipse。
公布文章时直接插入数据库会没有分段。这里的解决的方法是引入第三方工具wangEditor(wangEditor 是一款基于javascript和css开发的html富文本编辑器,开源免费。产品第一版公布于2014年11月。关于该编辑器:http://www.kancloud.cn/wangfupeng/wangeditor2/113961)
首先数据库的设计结构:
/* Navicat MySQL Data Transfer Source Server : blog Source Server Version : 50528 Source Host : localhost:3306 Source Database : novel Target Server Type : MYSQL Target Server Version : 50528 File Encoding : 65001 Date: 2016-12-31 16:04:07 */ SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for admin -- ---------------------------- DROP TABLE IF EXISTS `admin`; CREATE TABLE `admin` ( `id` int(11) NOT NULL AUTO_INCREMENT, `adminName` varchar(255) NOT NULL, `adminPassword` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; -- ---------------------------- -- Table structure for author -- ---------------------------- DROP TABLE IF EXISTS `author`; CREATE TABLE `author` ( `id` int(11) NOT NULL AUTO_INCREMENT, `authorName` varchar(255) NOT NULL, `authorPassword` varchar(255) NOT NULL, `authorEmail` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8; -- ---------------------------- -- Table structure for comment -- ---------------------------- DROP TABLE IF EXISTS `comment`; CREATE TABLE `comment` ( `id` int(11) NOT NULL AUTO_INCREMENT, `context` text, `createdTime` datetime DEFAULT NULL, `readerName` varchar(255) DEFAULT NULL, `novelId` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=67 DEFAULT CHARSET=utf8; -- ---------------------------- -- Table structure for genre -- ---------------------------- DROP TABLE IF EXISTS `genre`; CREATE TABLE `genre` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(255) DEFAULT NULL, `sort` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8; -- ---------------------------- -- Table structure for novel -- ---------------------------- DROP TABLE IF EXISTS `novel`; CREATE TABLE `novel` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) NOT NULL, `context` text NOT NULL, `createdTime` datetime DEFAULT NULL, `genreId` int(11) DEFAULT NULL, `voteNumber` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=160 DEFAULT CHARSET=utf8; -- ---------------------------- -- Table structure for reader -- ---------------------------- DROP TABLE IF EXISTS `reader`; CREATE TABLE `reader` ( `id` int(11) NOT NULL AUTO_INCREMENT, `readerName` varchar(255) NOT NULL, `readerPassword` varchar(255) NOT NULL, `readerEmail` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8;
项目的大致结构如图:
因为功能有点多。这里先介绍后台的实现,管理后台和前台互不交涉。
登录界面
后台主页:
1,小说管理
2,作者管理:
3,添加分类
后台其它导航页面基本雷同,这里不做一一介绍。
后台管理员登录处理代码:
public class Admin { Conn conn=new Conn(); /** * 推断登陆用户是否合法 * @param adminName * @param adminPassword * @return * @throws SQLException */ public boolean isExist(String adminName,String adminPassword)throws SQLException{ boolean result=false; AdminInfo ainfo=new AdminInfo(); String sql="select * from admin a where adminName=‘"+adminName+"‘and adminPassword=‘"+adminPassword+"‘"; System.out.println(sql); ResultSet rs=conn.executeQuery(sql); if(rs.next()){ ainfo.setAdminName(rs.getString("adminName")); ainfo.setAdminPassword(rs.getString("adminPassword")); result=true; } conn.close(); return result; } }
小说展示,管理。添加,删除,更新的代码处理:
public class Novel { Conn conn=new Conn(); /** * 获取小说列表 * @param keyword * @return * @throws SQLException */ public List<NovelInfo>getList(String keyword)throws SQLException{ List<NovelInfo> list=new ArrayList<NovelInfo>(); String sql="select n.*,g.name as genreName from novel n left join genre g on n.genreId=g.id"; if(DataValidator.isNullOrEmpty(keyword)){ sql=sql+ " order by id desc"; }else{ sql=sql+" where n.title like ‘%"+keyword+"%‘ order by id desc"; } ResultSet rs=conn.executeQuery(sql); while(rs.next()){ NovelInfo ninfo=new NovelInfo(); ninfo.setId(rs.getInt("Id")); ninfo.setTitle(rs.getString("Title")); ninfo.setContext(rs.getString("Context")); ninfo.setCreatedTime(rs.getDate("CreatedTime")); ninfo.setGenreId(rs.getInt("GenreId")); ninfo.setGenreName(rs.getString("genreName")); ninfo.setVoteNumber(rs.getInt("voteNumber")); list.add(ninfo); } conn.close(); return list; } /** * 获取某分类下的小说列表 * @param classId * @return * @throws SQLException */ public List<NovelInfo> getListBygenreId(int genreId) throws SQLException{ List<NovelInfo> list=new ArrayList<NovelInfo>(); String sql="select n.*,g.name as genreName from novel n left join genre g on n.genreId=g.id" + " where n.genreId="+genreId+" order by id desc"; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ NovelInfo info=new NovelInfo(); info.setId(rs.getInt("Id")); info.setTitle(rs.getString("Title")); info.setContext(rs.getString("Context")); info.setCreatedTime(rs.getDate("CreatedTime")); info.setGenreId(rs.getInt("GenreId")); info.setGenreName(rs.getString("genreName")); info.setVoteNumber(rs.getInt("voteNumber")); list.add(info); } conn.close(); return list; } /** * 依据ID获取小说 * @param id * @return * @throws SQLException */ public NovelInfo getNovelInfo(int id) throws SQLException{ NovelInfo info=new NovelInfo(); String sql="select n.*,g.name as genreName from novel n left join genre g on n.genreId=g.id where n.id="+id+""; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ info.setId(rs.getInt("Id")); info.setTitle(rs.getString("Title")); info.setContext(rs.getString("Context")); info.setCreatedTime(rs.getDate("CreatedTime")); info.setGenreId(rs.getInt("GenreId")); info.setGenreName(rs.getString("genreName")); info.setVoteNumber(rs.getInt("voteNumber")); } conn.close(); return info; } /** * 写入新小说 * * @param info * @return */ public int insert(NovelInfo info){ String sql="insert into novel(title,conText,createdTime,genreId,voteNumber)values"; sql=sql+"(‘"+info.getTitle()+"‘,‘"+info.getContext()+"‘,now(),‘"+info.getGenreId()+"‘,"+info.getVoteNumber()+")"; int result=0; System.out.println(sql); result=conn.executeUpdate(sql); conn.close(); return result; } /** *更新小说 * @param info * @return */ public int update(NovelInfo info){ String sql="update novel set "+" Title=‘"+info.getTitle()+"‘,Context=‘"+info.getContext()+"‘," + "genreId=‘"+info.getGenreId()+"‘where id="+info.getId()+""; int result=0; System.out.println(sql); result=conn.executeUpdate(sql); conn.close(); return result; } /** * 删除小说 * @param id * @return */ public int delete(int id){ String sql="delete from novel where id="+id+""; int result=0; result=conn.executeUpdate(sql); conn.close(); return result; } /** * 添加票数 * @return */ public int addVote(int num){ return 0; } }
小说评论展示,管理,添加,删除,更新的代码处理:
public class Comment { Conn conn=new Conn(); /** * 获取评论列表 * @return * @throws SQLException */ public List<CommentInfo> getList() throws SQLException{ List<CommentInfo> list=new ArrayList<CommentInfo>(); String sql="select * from comment order by id desc"; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ CommentInfo info=new CommentInfo(); info.setId(rs.getInt("Id")); info.setContext(rs.getString("Context")); info.setNovelId(rs.getInt("NovelId")); info.setCreatedTime(rs.getDate("CreatedTime")); info.setReaderName(rs.getString("ReaderName")); list.add(info); System.out.print(list); } conn.close(); return list; } /** * * @param classId * @return * @throws SQLException */ public CommentInfo getCommentInfo(int id)throws SQLException{ CommentInfo info=new CommentInfo(); String sql="select * from Comment c where id="+id+""; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ info.setId(rs.getInt("Id")); info.setContext(rs.getString("Context")); info.setNovelId(rs.getInt("NovelId")); info.setCreatedTime(rs.getDate("CreatedTime")); info.setReaderName(rs.getString("ReaderName")); } conn.close(); return info; } /** * 获取某小说下的评论 * @param id * @return * @throws SQLException */ public List<CommentInfo> getListByNovelId(int novelid) throws SQLException{ List<CommentInfo> list=new ArrayList<CommentInfo>(); String sql="select * from comment where novelId="+novelid+" order by id desc"; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ CommentInfo info=new CommentInfo(); info.setId(rs.getInt("Id")); info.setContext(rs.getString("Context")); info.setNovelId(rs.getInt("NovelId")); info.setCreatedTime(rs.getDate("CreatedTime")); info.setReaderName(rs.getString("ReaderName")); list.add(info); } conn.close(); return list; } /** * 插入评论 * @param info * @return */ public int insert(CommentInfo info){ String sql="insert into Comment(Context,CreatedTime,readerName,novelId)values"; sql=sql+"(‘"+info.getContext()+"‘,now(),‘"+info.getReaderName()+"‘,"+info.getNovelId()+")"; int result=0; System.out.println(sql); result=conn.executeUpdate(sql); conn.close(); return result; } /** * 更新评论 * @param info * @return */ public int update(CommentInfo info){ String sql="update Comment set "+" Context=‘"+info.getContext()+"‘,novelId=‘"+info.getNovelId()+"‘," + "CreatedTime=‘"+info.getCreatedTime()+"‘,readerName=‘"+info.getReaderName()+"‘ where id="+info.getId()+""; int result=0; System.out.println(sql); result=conn.executeUpdate(sql); conn.close(); return result; } /** * 删除评论 * @param id * @return */ public int delete(int id){ String sql="delete from Comment where id="+id+""; int result=0; result=conn.executeUpdate(sql); System.out.println(sql); conn.close(); return result; } }
小说分类展示。更新。添加,删除的代码处理:
public class Genre { Conn conn=new Conn(); /** * 获取分类列表 * @return * @throws SQLException */ public List<GenreInfo> getList()throws SQLException{ List<GenreInfo> list=new ArrayList<GenreInfo>(); String sql="select * from genre order by Sort asc"; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ GenreInfo info=new GenreInfo(); info.setId(rs.getInt("Id")); info.setName(rs.getString("Name")); info.setSort(rs.getInt("Sort")); list.add(info); } conn.close(); return list; } /** * * @param id * @return * @throws SQLException */ public GenreInfo getGenreInfo(int id)throws SQLException{ GenreInfo info=new GenreInfo(); String sql="select * from genre g where id="+id+""; ResultSet rs=conn.executeQuery(sql); while(rs.next()){ info.setId(rs.getInt("Id")); info.setName(rs.getString("Name")); info.setSort(rs.getInt("Sort")); } conn.close(); return info; } /** * 添加分类 * @param info * @return */ public int insert(GenreInfo info){ String sql="insert into genre(Name,Sort) values"; sql=sql+"(‘"+info.getName()+"‘,‘"+info.getSort()+"‘)"; int result=0; result=conn.executeUpdate(sql); conn.close(); return result; } /** * 更新分类 * * @param info * @return */ public int update(GenreInfo info){ String sql="update genre set "+" Name=‘"+info.getName()+"‘,Sort= ‘"+info.getSort()+"‘ where id="+info.getId()+""; int result=0; result=conn.executeUpdate(sql); return result; } public int delete(int id){ String sql="delete from genre where id="+id+""; int result=0; result=conn.executeUpdate(sql); conn.close(); return result; } }
前台主要页面展示:(略丑)
作者公布小说界面:
读者评论界面:
为小说投票,投票功能的前端设计代码:
function getElemensByClassName(className){ // 通过class获取 var classArr = new Array(); var tags = document.getElementsByTagName("*"); //获取全部节点 for(var item in tags){ if(tags[item].nodeType == 1){ if(tags[item].getAttribute("class") == className){ classArr.push(tags[item]); //收集class匹配的节点 } } } return classArr; } function delete_FF(element){ // 在FireFox中删除子节点为空的元素 var childs = element.childNodes; for(var i=0;i<childs.length;i++){ var pattern = /\s/; //模式匹配,内容为空 if(childs[i].nodeName == "#text" && pattern.test(childs[i].nodeValue)){ //处理 //alert(childs[i].nodeName); element.removeChild(childs[i]); //删除FF中获取的空节点 } } } function $(obj){return document.getElementById(obj);} window.onload = function(){ onload1(); onload2(); }; function onload2(){ var persons = getElemensByClassName("person"); // alert(persons); for(var item in persons){ //遍历全部person。为它们绑定投票事件 (function(_item){ //匿名函数传入item, 防止因作用域问题导致item总为最后一个 delete_FF(persons[_item]); //出去FF中空行代表的子节点 persons[_item].setAttribute("id","person"+(parseInt(_item)+1)); //赋上id var childs = persons[_item].childNodes; for(var i = 0;i<childs.length;i++){ //alert(childs[i].nodeName); if(childs[i].nodeName == "BUTTON"){ //点击按钮投票 var oButton = childs[i]; } if(childs[i].nodeName == "P"){ //投票结果更新 var oP = childs[i]; var oSpan = oP.getElementsByTagName("span")[0]; } } if(oButton != null){ oButton.onclick = function(){ //事件绑定 var num = oSpan.innerHTML; //获取票数 oSpan.innerHTML = (++num); //票数更新 // 这时一般我们可能就须要把这个票数num传送给server保存。更新时也是和server中的num同步 this.setAttribute("disabled","true"); // 一般仅仅能投票一次的吧 alert("投票成功,谢谢您的支持"); }; } })(item); // 传入各项person } }
小说公布的实现细节,引入了wangEditor:
