mvnforum 精華文章功能範例
最近一直在看mvnforum sad

遗憾的是到现在对代码还不是很熟悉。花了接近一天的时间才写出来，贴上来和大家一起探讨学习 smile

本次修改参考了wangyi的帖子http://www.shorelinesolution.com/forum/viewthread?thread=115#480 上次写了论坛实现版主功能的帖子，jing 还有wangyi提了很好的建议，同时在他们那也学到很多东西 laughing

受益非浅。在此表示感谢。废话不多说了 smile

首先需要改的页面文件为：listforums.jsp、listthreads.jsp、editthreadtype.jsp。
listforums.jsp里面加入的代码为：
<% String typeImage = "";
switch (thread.getThreadType()) {
case ThreadBean.THREAD_TYPE_STICKY: typeImage = "sticky.gif"; hasSticky = true; break;
case ThreadBean.THREAD_TYPE_FORUM_ANNOUNCEMENT: typeImage = "announce.gif"; hasAnnouncement = true; break;
case ThreadBean.THREAD_TYPE_GLOBAL_ANNOUNCEMENT: typeImage = "global_announce.gif"; hasGlobalAnnouncement = true; break;
//////add by dyhjjk begin
case ThreadBean.THREAD_TYPE_PINK: typeImage="[精华]";
//////end

default:break;
} %>
<% if ( thread.getThreadType() != ThreadBean.THREAD_TYPE_DEFAULT) { %>


<%
if(thread.getThreadType()==ThreadBean.THREAD_TYPE_PINK){
out.print("<font color=red>"+typeImage+"</font>");
}else{
%>


<img src="<%=contextPath%>/mvnplugin/mvnforum/images/icon/<%=typeImage%>"/>


<%}%>

listthreads.jsp里面加入的代码为：
<% String typeImage = "";
switch (threadBean.getThreadType()) {
case ThreadBean.THREAD_TYPE_STICKY: typeImage = "sticky.gif"; hasSticky = true; break;
case ThreadBean.THREAD_TYPE_FORUM_ANNOUNCEMENT: typeImage = "announce.gif"; hasAnnouncement = true; break;
case ThreadBean.THREAD_TYPE_GLOBAL_ANNOUNCEMENT: typeImage = "global_announce.gif"; hasGlobalAnnouncement = true; break;

//***************add by dyhjjk**************************
case ThreadBean.THREAD_TYPE_PINK: typeImage="[精华]";
break;
//***************add by dyhjjk**************************

default:break;
} %>
<% if ( threadBean.getThreadType() != ThreadBean.THREAD_TYPE_DEFAULT) {
%>


<%
if(threadBean.getThreadType()==ThreadBean.THREAD_TYPE_PINK){
out.print("<font color=red>"+typeImage+"</font>");
}else{
%>

<img src="<%=contextPath%>/mvnplugin/mvnforum/images/icon/<%=typeImage%>"/>


<% }%>
editthreadtype.jsp中加入的代码为：

<%
if (threadType!=4){
%>
<option id="4" value="4"> 精华贴</option>
<%}%>

需要改的类文件有：
ThreadBean.java
/****
* add by dyhjjk 设置精华帖子
*/

public final static int THREAD_TYPE_PINK = 4;

public final static int THREAD_TYPE_FORUM_ANNOUNCEMENT = 2;
/**********
* modify by dyhjjk
*/
public final static int THREAD_TYPE_GLOBAL_ANNOUNCEMENT = 5;
ThreadDAO.java
/*****************
* add by dyhjjk 获得精华帖子
* @param forumID
* @return
* @throws DatabaseException
*/
public Collection getPinkForum(int forumID)
throws DatabaseException;
ThreadCache.java
/******************
* add by dyhjjk 返回精华帖子
* @return
* @throws DatabaseException
*/
public Collection getPinkForum(int forumID)
throws DatabaseException {

Collection result = null;
if (cache != null) {
StringBuffer buffer = new StringBuffer(128);
buffer.append("getPinkForum").append(forumID);
String key = buffer.toString();
result = (Collection)cache.retrieve(key);
if (result == null) {
result = DAOFactory.getThreadDAO().getPinkForum(forumID);

cache.store(key, result, TIME_OUT);
}
} else {
result = DAOFactory.getThreadDAO().getPinkForum(forumID);
}

return result;
}
ThreadDAOImplJDBC.java
/*****************
* add by dyhjjk 获得精华帖子
*/
public Collection getPinkForum(int forumID)throws DatabaseException{
return getEnableThreads_inType_inForum(forumID,ThreadBean.THREAD_TYPE_PINK);
}
ThreadWebHandler.java
在prepareList_limit（）中加入

/***********
*add by dyhjjk 从缓存中取得精华帖子
*/
Collection pinkforum=ThreadCache.getInstance().getPinkForum(forumID);
allThreadBeans.addAll(pinkforum);
MyUtil.java
getThreadTypeName中加入
/*************
* modify by dyhjjk
*/

case ThreadBean.THREAD_TYPE_PINK:
result="精华贴";
break;
