在线小说网站的设计与实现（附源码）

最近在做一个课程设计，在线小说网站的设计，以下是课题要求，需要项目练手的童鞋可以试试身手。

由于最近新学了JavaEE，所以采用了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。

发布文章时直接插入数据库会没有分段，这里的解决办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。产品第一版发布于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：

) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8;

项目的大致结构如图：

由于功能有点多，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，增加分类

后台其他导航页面基本雷同，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();/*** 判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，增加，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;}/*** 根据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;}/*** 增加票数* @return*/public int addVote(int num){return 0;}
}

小说评论展示，管理，增加，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，增加，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;}/*** 增加分类* @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）

作者发布小说界面：

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("*"); //获取所有节点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){  //遍历所有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idvar 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需要把这个票数num传送给服务器保存，更新时也是和服务器中的num同步this.setAttribute("disabled","true"); // 一般只能投票一次的吧alert("投票成功，谢谢您的支持");};}
})(item); // 传入各项person}
}

小说发布的实现细节，引入了wangEditor：

好吧，由于代码段较多，这里不能一一介绍，后续直接介绍一下这个项目开发过程中的错误细节，完善之后把源码上传到资源那里，这个项目实现起来较简单，童鞋们可以根据设计要求试试身手哦！
