在线小说网站的设计与实现（附源码）-阿里云开发者社区

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：

/*
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

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

	 */
	
	public List<NovelInfo>getList(String keyword)throws SQLException{

		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{

小说评论展示，管理，增加，删除，更新的代码处理：

小说分类展示，更新，增加，删除的代码处理：

	}
	
}

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
  }
}

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！
