在线小说站点的设计与实现（附源代码）

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：

/*

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：

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();
	/**

小说分类展示。更新。添加，删除的代码处理：

}

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
  }
}

  好吧，因为代码段较多，这里不能一一介绍，兴许直接介绍一下这个项目开发过程中的错误细节，完好之后把源代码上传到资源那里，这个项目实现起来较简单，童鞋们能够依据设计要求试试身手哦！
