美化的bbs项目

跟着教程做两天的bbs项目，终于好了，做了点笔记上传上来，哈哈（这里已经成了我的备忘录笔记本了啊）。

开发工具-----MyEclipse6.0：基于插件结构的开发工具，定义了许多接口。Eclipse默认只支持J2SE，lomboz-Eclipse和MyEclipse在Eclipse的基础上装了许多插件。

项目需要注理解的一些地方：

<%
String path=request.getContextPath(); //相当用于访问这个文件的路径，默认下也相当于文件名（如我们的第一个文件就是TestMyEclipse）
String basePath=request.getSchema()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; //相当于http://127.0.0.1:8888/TestMyEclipse/
%>

html中的base标签：
<base href="<%=basePath%>">
则其范围内的所有链接都是基于它的相对路径：
如： <a href="aaaa.html">aaaa</a>
的实际路径为： http://127.0.0.1:8888/TestMyEclipse/aaaa.html

项目的主要过程：

<1.将静态页面改为动态页面：
<<1.首先可以上网找一些自己觉得做的好的页面下载下来，然后调整页面，删除不必要的东西（我下载下来的文件叫做article.htm）

<<2.讲article.htm转换为article.jsp（静态页面htm->动态页面jsp）

-----article.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*, com.bjsxt.bbs.*, java.util.*"%>

<%!
private void tree(List<Article> articles, Connection conn, int id, int grade) { //定义递归函数，以树状的形式显示帖子列表
String sql = "select * from article where pid = " + id; //找出所有父节点是id的节点
Statement stmt = DB.createStmt(conn);
ResultSet rs = DB.executeQuery(stmt, sql);
try {
while(rs.next()) {
Article a = new Article();
a.initFromRs(rs);
a.setGrade(grade);
articles.add(a);
if(!a.isLeaf()) { //如果此节点不是叶子节点，调用函数，找出其子节点
tree(articles, conn, a.getId(), grade + 1);
}
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
DB.close(rs);
DB.close(stmt);
}
}
%>

<%
List<Article> articles = new ArrayList<Article>(); //定义一个ArrayList有序存放Ariticle
Connection conn = DB.getConn();
tree(articles, conn, 0, 0);
DB.close(conn);
%>

<3.详细展示帖子内容（将article_detail由静态页面htm转换为动态的JSP页面）：

-----article_detail.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*, com.bjsxt.bbs.*" %>

<%
String strId = request.getParameter("id"); //接收Article.jsp传递过来的参数，参数的传递都是以字符串的形式进行的
if(strId == null || strId.trim().equals("")) { //判断传递过来的参数是否合法，strId == null || strId.trim().equals("")-----这两个检测条件顺序不可调换，因为若参数是null值，则执行strId.trim().equals("")时出现空指针错误
out.println("Error ID!");
return;
}
int id = 0;
try {
id = Integer.parseInt(strId);
} catch (NumberFormatException e) { //若strId为错误的字符串，不可转换为数字时，出现异常
out.println("Error ID Again!");
return;
}

Article a = null;

Connection conn = DB.getConn();
String sql = "select * from article where id = " + id;
Statement stmt = DB.createStmt(conn);
ResultSet rs = DB.executeQuery(stmt, sql);
if(rs.next()) {
a = new Article();
a.initFromRs(rs);
}

DB.close(rs);
DB.close(stmt);
DB.close(conn);

if(a == null) {
%>
您寻找的帖子不存在！

<4.增加回复功能：

-----reply.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*, com.bjsxt.bbs.*" %>

<%
int id = Integer.parseInt(request.getParameter("id")); //接受article.detail传递过来的参数id和rootid
int rootId = Integer.parseInt(request.getParameter("rootId"));
%>

window.onload = function()
{
// Automatically calculates the editor base path based on the _samples directory.
// This is usefull only for these samples. A real application should use something like this:
// oFCKeditor.BasePath = ‘/fckeditor/‘ ; // ‘/fckeditor/‘ is the default value.
// var sBasePath = document.location.pathname.substring(0,document.location.pathname.lastIndexOf(‘_samples‘)) ;
var sBasePath = "<%=request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath() + "/fckeditor/" %>"
//alert(sBasePath);
var oFCKeditor = new FCKeditor( ‘cont‘ ) ;
oFCKeditor.BasePath = sBasePath ;
oFCKeditor.ReplaceTextarea() ;
}

</script>

-----replyDeal.jsp-----

<%@ page language="java" import="java.util.*, java.sql.*, com.bjsxt.bbs.*" pageEncoding="GB18030"%>

<%
request.setCharacterEncoding("GBK");

int pid = Integer.parseInt(request.getParameter("pid")); //上一个页面的id是这一个页面的pid
int rootId = Integer.parseInt(request.getParameter("rootId"));

String title = request.getParameter("title");
System.out.println(title);
String cont = request.getParameter("cont");
System.out.println(cont);
Connection conn = DB.getConn();

boolean autoCommit = conn.getAutoCommit();
conn.setAutoCommit(false); //设置同步性，避免出错

String sql = "insert into article values (null, ?, ?, ?, ?, now(), ?)"; //向数据库增加一条记录
PreparedStatement pstmt = DB.prepareStmt(conn, sql);
pstmt.setInt(1, pid);
pstmt.setInt(2, rootId);
pstmt.setString(3, title);
pstmt.setString(4, cont);
pstmt.setInt(5, 0);
pstmt.executeUpdate();

Statement stmt = DB.createStmt(conn);
stmt.executeUpdate("update article set isleaf = 1 where id = " + pid); //当此帖被回复是，变成非叶子节点

conn.commit();
conn.setAutoCommit(autoCommit);
DB.close(pstmt);
DB.close(stmt);
DB.close(conn);

<span id="time" //指定id号，动态的拿到这个span style="background:red">5</span>秒钟后自动跳转，如果不跳转，请点击下面链接

//-->

</script>

<a href="article.jsp">主题列表</a>
<script type="text/javascript">
delayURL("article.jsp");
</script>

<5.FCKeditor-----增加在线编辑器（javascript写的客户端控件）

<6.增加功能，回复成功后，5秒钟转到主题帖页面：

具体内容在上面replyDeal.jsp中。

Snippets:为收集进来的代码，想用随时加。

输出和删一段改一段是比较常用的调试方法。

<7.发表新主题贴：

-----post.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*,com.bjsxt.bbs.*"%>

<%
request.setCharacterEncoding("GBK");
String action = request.getParameter("action"); //拿到action
if (action != null && action.trim().equals("post")) { //判断是链接过来还是提交过来的
String title = request.getParameter("title"); //若是提交过来，则接受各个参数
System.out.println(title);
String cont = request.getParameter("cont");
System.out.println(cont);
Connection conn = DB.getConn();

boolean autoCommit = conn.getAutoCommit();
conn.setAutoCommit(false);

int rootId = -1; //由于id是自动生成的，则利用Statement.RETURN_GENERATED_KEYS*****这个注意

String sql = "insert into article values (null, ?, ?, ?, ?, now(), ?)";
PreparedStatement pstmt = DB.prepareStmt(conn, sql, Statement.RETURN_GENERATED_KEYS);
pstmt.setInt(1, 0);
pstmt.setInt(2, rootId); //将自身的id设置为rootid
pstmt.setString(3, title);
pstmt.setString(4, cont);
pstmt.setInt(5, 0);
pstmt.executeUpdate();

ResultSet rsKey = pstmt.getGeneratedKeys();
rsKey.next();
rootId = rsKey.getInt(1);

Statement stmt = DB.createStmt(conn);
stmt.executeUpdate("update article set rootid = " + rootId + " where id = " + rootId);

conn.commit();
conn.setAutoCommit(autoCommit);
DB.close(pstmt);
DB.close(stmt);
DB.close(conn);

response.sendRedirect("article.jsp"); //完成对数据库的更新后，重新定向到article.jsp

}
%>

<9.增加管理员管理功能（如：删除，登录）：

-----delete.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*, com.bjsxt.bbs.*, java.util.*"%>

<%@ include file="_SessionCheck.jsp" %> //包含_SessionCheck.jsp判断请求页面delete.jsp时是否已经登录

<%!
private void delete(Connection conn, int id, boolean isLeaf) { //利用递归函数删除帖子及其子贴
//delete all the children
//delete(conn, chids‘s id)

if(!isLeaf) { //判断其是否为叶子节点
String sql = "select * from article where pid = " + id;
Statement stmt = DB.createStmt(conn);
ResultSet rs = DB.executeQuery(stmt, sql);
try {
while(rs.next()) {
delete(conn, rs.getInt("id"), rs.getInt("isleaf") == 0);
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
DB.close(rs);
DB.close(stmt);
}
}

//delete self
DB.executeUpdate(conn, "delete from article where id = " + id); //是叶子节点直接删除自己就可以

}
%>

<%
int id = Integer.parseInt(request.getParameter("id")); //接受参数
int pid = Integer.parseInt(request.getParameter("pid"));
boolean isLeaf = Boolean.parseBoolean(request.getParameter("isLeaf"));
String url = request.getParameter("from");
System.out.println("url = " + url);
Connection conn = null;
boolean autoCommit = true;
Statement stmt = null;
ResultSet rs = null;

try {
conn = DB.getConn();
autoCommit = conn.getAutoCommit();
conn.setAutoCommit(false);

delete(conn, id, isLeaf); //调用函数

stmt = DB.createStmt(conn);
rs = DB.executeQuery(stmt, "select count(*) from article where pid = " + pid);
rs.next();
int count = rs.getInt(1);

if(count <= 0) { //判断他是否还有子节点，若没有则将其改为子节点
DB.executeUpdate(conn, "update article set isleaf = 0 where id = " + pid);
}

conn.commit();
} finally {
conn.setAutoCommit(autoCommit);
DB.close(rs);
DB.close(stmt);
DB.close(conn);
}
response.sendRedirect(url); //转回到被点击删除按钮的那个页面
%>

-----login.jsp----- //管理员登录界面

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*,com.bjsxt.bbs.*"%>

<%
request.setCharacterEncoding("GBK");
String action = request.getParameter("action"); //接收参数
String username = "";
if (action != null && action.trim().equals("login")) {
username = request.getParameter("username"); //接收参数
//check username whether valid or not!
String password = request.getParameter("password"); //接受参数
if(username == null || !username.trim().equals("admin")) { //判断用户名是否正确
out.println("username not correct!");
} else if(password == null || !password.trim().equals("admin")) { //判断密码是否正确
out.println("password not correct!");
} else {
session.setAttribute("adminLogined" , "true"); //在session中放入adminLogined，值为true，代表已经登录,在其他页面取这个值，就可以知道是否已经登录
response.sendRedirect("articleFlat.jsp"); //登录成功后转到articleFlat.jsp页面
}
}
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>管理员登录</title>

</head>
<body>

<form action="login.jsp" method="post"> //提交到自身，提交密码使用post方式
<input type="hidden" name="action" value="login"/> //使用隐藏域区分是自身还是点删除时转到此页面的
用户名：
<input type="text" name="username" value="<%=username %>"/> //value="<%=username %>-----小技巧，可以记住之前输入的用户名
<br>
密码：
<input type="password" name="password" />
<br>
<input type="submit" value="login" />
</form>

</body>
</html>

<10.加入一个检查session的页面：

----- _SessionCheck.jsp -----

<%
String adminLogined = (String)session.getAttribute("adminLogined");
if(adminLogined == null || !adminLogined.trim().equals("true")) {
response.sendRedirect("login.jsp");
return; //当转到另一个页面时加上return，使这个页面不再进行
}
%>

<10.程序打包问题(Web程序)：

<<1.在项目上点击export/j2ee/war file/选择存放路径/finish
<<2.将生成的war文件拷贝到web server（tomcat）上，启动web server，即可浏览文件。

<11.加入管理员更新操作：

-----modify.jsp-----

<%@ page pageEncoding="GB18030"%>
<%@ page import="java.sql.*,com.bjsxt.bbs.*"%>

<%
request.setCharacterEncoding("GBK");
String action = request.getParameter("action");

int id = Integer.parseInt(request.getParameter("id")); //接收传递过来的id，让数据库知道要修改的帖子的id
if (action != null && action.trim().equals("modify")) {
Connection conn = DB.getConn();
String title = request.getParameter("title"); //获得修改后的title
System.out.println(title);
String cont = request.getParameter("cont"); //获得修改后的cont
System.out.println(cont);

PreparedStatement pstmt = DB.prepareStmt(conn, "update article set title = ? , cont = ? where id = ?"); //更新数据库
pstmt.setString(1, title);
pstmt.setString(2, cont);
pstmt.setInt(3, id);
pstmt.executeUpdate();

DB.close(pstmt);
DB.close(conn);

response.sendRedirect("articleFlat.jsp");
return;

}
%>

<% //从数据库中取出要更新的那个帖子
Connection conn = DB.getConn();
Statement stmt = DB.createStmt(conn);
ResultSet rs = DB.executeQuery(stmt, "select * from article where id = " + id);
if(!rs.next()) return; //确定rs中是否有内容
Article a = new Article();
a.initFromRs(rs); //取出其中的内容
DB.close(rs);
DB.close(stmt);
DB.close(conn);
%>

<form action="modify.jsp" method="post">
<input type="hidden" name="action" value="modify" /> //利用隐藏域判断是从哪个页面链接过来的
<input type="hidden" name="id" value="<%=id %>"/> //将要修改的那个帖子的id传递出去

标题：
<input type="text" name="title" value="<%=a.getTitle() %>"> //将取出的帖子的标题显示出来
<br>
内容：
<textarea name="cont" rows="15" cols="80"><%=a.getCont() %></textarea> //将取出的帖子的内容显示出来
<br>
<input type="submit" value="submit" />
</form>

</div>
</div>
</div>
<div class="jive-message-list-footer">
<br>
</div>
</div>
</td>
<td width="1%">
 
</td>
</tr>

</table>

<12.项目总结：

学习一个web项目是怎么样的，为下一个项目做准备。

掌握的技巧，通过页面往数据库中增加，删除，修改数据的方法。

增加搜索功能：

}
%>

<%
String keyword = new String(request.getParameter("keyword").getBytes("8859_1"), "GBK"); //通过http协议传递过来的中文都是以8859_1编码的
if(keyword == null) keyword = "";

final int PAGE_SIZE = 4;
int pageNo = 1;
String strPageNo = request.getParameter("pageNo");
if(strPageNo != null && !strPageNo.trim().equals("")) {
try {
pageNo = Integer.parseInt(strPageNo);
} catch (NumberFormatException e) {
pageNo = 1;
}
}

int totalPages = 0;

List<Article> articles = new ArrayList<Article>();
Connection conn = DB.getConn();

Statement stmtCount = DB.createStmt(conn);
String sqlCount = "select count(*) from article where title like ‘%" + keyword
+ "%‘ or cont like ‘%" + keyword + "%‘";
System.out.println(sqlCount);
ResultSet rsCount = DB.executeQuery(stmtCount, sqlCount);
rsCount.next();
int totalRecords = rsCount.getInt(1);

totalPages = (totalRecords + PAGE_SIZE - 1)/PAGE_SIZE;

if(pageNo > totalPages) pageNo = totalPages;

if(pageNo <= 0) pageNo = 1;

Statement stmt = DB.createStmt(conn);
int startPos = (pageNo-1) * PAGE_SIZE;
String sql = "select * from article where title like ‘%" + keyword
+ "%‘ or cont like ‘%" + keyword + "%‘ order by pdate desc limit " + startPos + "," + PAGE_SIZE ; //从数据库中搜索出所有要的记录
System.out.println(sql);
ResultSet rs = DB.executeQuery(stmt, sql);
while(rs.next()) {
Article a = new Article();
a.initFromRs(rs);
articles.add(a);
}
DB.close(rsCount);
DB.close(stmtCount);

DB.close(rs);
DB.close(stmt);
DB.close(conn);
