本文深入解析了一个论坛系统的架构设计，包括论坛历史记录展示、精华帖管理、搜索功能实现、订阅主题管理和发帖流程控制等核心模块。通过具体的代码示例和技术细节说明，为读者提供了全面的技术指导。

我们在forumHistory.jsp中发现其与forum.jsp十分类似，不同之处:
          <div id="t<s:property value="#f.id"/>">
            <span class="font1"><bbscs:forum forumValue="#f" type="titlehistory" currentPageValue="%{page}"/></span>
            <bbscs:forum forumValue="#f" type="titleitemhistory" currentPageValue="%{page}"/>
          </div>
我们到forumComponent.java中找到其相关的tag，可发现其与title 十分相似，只是其URL不同而已！
sb.append(BBSCSUtil.getActionMappingURL("/read?action=history&id=" + f.getMainID() + "&bid="
       + f.getBoardID() + "&fcpage=" + fcpage + "&fcaction=" + fcaction + "&tagId=" + tagId,
       request));
同样，我们也知道最后需要sb.append(TextUtils.htmlEncode(f.getTitle()));对字符串的格式化！在forumHistory.jsp中有个存档项，上前列出了存档的时间，点击将触发相应的历史记录列表显示：http://bbs.laoer.com/archives/15/2007-01/1.html，其代码如下：
      <s:iterator id="month" value="%{archivesMonth}">
      [<a href="archives/<s:property value="%{bid}"/>/<s:property value="#month"/>/1.html" target="_blank"><s:property value="#month"/></a>]
      </s:iterator>
好的，我们点击后链接到静态页面上，在列表中选择又将打开其静态化的帖子内容！archives是skin目录下的.好的，我们看精华帖http://bbs.laoer.com/refine.bbscs?action=index&pid=0&bid=6,我们看refine在struts.xml中的定义：
<action name="refine" class="refineAction">
   <interceptor-ref name="boardInterceptorStack"></interceptor-ref>
   <result name="refine">/WEB-INF/jsp/refine.jsp</result>
   <result name="refineManage">/WEB-INF/jsp/refineManage.jsp</result>
   <result name="success" type="redirect">${forwardUrl}</result>
</action>
先从index方法看起:
public String index() {
Elite elite = this.getEliteService().findEliteByID(this.getPid());//pid找起
if (elite != null) {
   List pes = elite.getParentIDs();
   for (int i = 0; i < pes.size(); i++) {
    Elite pe = this.getEliteService().findEliteByID(((Long) pes.get(i)).longValue());//上上pid！
    eliteDirs.add(pe);//上上的精华帖
   }
   eliteDirs.add(elite);//最后才加入自己
}
return "refine";
}
注意在refine.jsp中eliteDirs是用于显示精华目录并有链接用的！(如:社区技术是当前的上当，而eliteDirs是它的父及组的目录),下面的代码是关键的显示：
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
    <td class="bgColor3"><table width="100%" border="0" cellpadding="5" cellspacing="1">
      <tr>
        <td width="5%"><div align="center"><s:text name="refine.type"/></div></td>
        <td width="55%"><div align="center"><s:text name="forum.art.title"/></div></td>
        <td width="12%"><div align="center"><s:text name="forum.author"/></div></td>
        <td width="12%"><div align="center"><s:text name="read.e.doename"/></div></td>
        <td width="16%"><div align="center"><s:text name="read.e.doetime"/></div></td>
      </tr>
      <tbody id="eliteList"></tbody>
      <tbody id="forumList"></tbody>
    </table></td>
</tr>
</table>
注意到script:
<script language="JavaScript" type="text/javascript">

</script>
<script type="text/javascript" src="js/jsMsg.jsp"></script>
<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/comm.js"></script>

</head>
<body onload="loadPage();">//启动！
function loadPage() {
loadElitePage();
//loadFlistPage(); ForumList!不用了
}

function loadElitePage() {
var url = getActionMappingURL("/refine");
var pars = "action=showelite&ajax=xml&bid="+bid+"&pid="+pid;

var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: showEliteListJson});
}

function showEliteListJson(res) {
var nowelites = $('eliteList').childNodes;
for (var i = 0; i < nowelites.length; i++) {
$('eliteList').removeChild(nowelites[i]);
}
var resText = res.responseText;
var jsonObj = eval('(' + resText + ')');
//alert(jsonObj);
//alert(jsonObj.forum);
//jsonObj.forum.each(function(f){
// alert(f.title);
//})
var dirs = jsonObj.dir; //dir部分!
for (var i = 0; i < dirs.length; i++) {
var row = document.createElement("tr");
row.setAttribute("id", "tre_"+dirs[i].id);

var cell = document.createElement("td");
var msgDiv = document.createElement("div");
msgDiv.innerHTML = "<img src="images/dir.gif" />";
cell.appendChild(msgDiv);

$('eliteList').appendChild(row);
}
var forums = jsonObj.forum; //内容部分！！
//alert(forums);
for (var i = 0; i < forums.length; i++) {
var row = document.createElement("tr");
row.setAttribute("id", "trf_"+forums[i].id);

}
我们接下来看forumSearch.bbscs它支持按主题和作者进行简单查询！
<action name="forumSearch" class="forumSearchAction">
   <interceptor-ref name="boardInterceptorStack"></interceptor-ref>
   <result name="success">/WEB-INF/jsp/forumSearch.jsp</result>
</action>
public String index() {
if (StringUtils.isBlank(this.getText())) {
   this.addActionError(this.getText("error.nullerror"));
   return ERROR;
}
Pages pages = new Pages();
pages.setPage(this.getPage());
pages.setPerPageNum(40);//分页数！
String text = "";
try {
   text = java.net.URLEncoder.encode(this.getText(), Constant.CHARSET);
} catch (UnsupportedEncodingException ex) {
   text = "";
}
pages.setFileName(BBSCSUtil.getActionMappingURLWithoutPrefix("/forumSearch?bid=" + this.getBid() + "&con="
    + this.getCon() + "&text=" + text));//构造一个分页显示的URL
if (this.getTotal() > 0) {
   pages.setTotalNum(this.getTotal());
}
this.setPageList(this.getForumService().getSearchList(this.getBid(), this.getCon(), this.getText(), pages));//con是条件！title是主题,userName是作者名
return SUCCESS;
}
我们看看forumSearch.jsp,其实也就是对pageList.objectList的遍历而已!这里值得注意的是它的返回按钮！接下来是[已订阅主题]subs.bbscs?action=index&bid=15:
<action name="subs" class="subsAction">
   <interceptor-ref name="boardInterceptorStack"></interceptor-ref>
   <interceptor-ref name="requestBasePathInterceptor"></interceptor-ref>
   <result name="subsmy">/WEB-INF/jsp/subsmy.jsp</result>
   <result name="list">/WEB-INF/jsp/subsList.jsp</result>
</action>
public String index() {
return "subsmy";
}
在index方法中直接定位到subsmy.jsp中,而这个文件中只有一个<body onload="loadSubsList('<s:property value="%{bid}"/>');">和js/subs.js以及一个空的div用于显示列表:
function loadSubsList(bid) {
$('subsList').innerHTML = pageLoading;

var url = getActionMappingURL("/subs");
var pars = "action=list&ajax=shtml&bid="+bid;

CancleSubsAjax.prototype = {
initialize: function(action,bid,id,cpage) {
   this.action = action;
   this.bid = bid;
   this.id = id;
   this.cpage = cpage;
},

cancle: function() {

    var url = getActionMappingURL("/subs");
    var pars = "ajax=xml&action=" + this.action + "&id=" + this.id + "&bid=" + this.bid;
    var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: this.cancleCompleted.bind(this)});
},

cancleCompleted: function(res) {
   resText = res.responseText;
   var jsonMsgObj = new JsonMsgObj(resText);
   var codeid = jsonMsgObj.getCodeid();
   alert(jsonMsgObj.getMessage());
   if (codeid == "0") {
    if (this.action == "delemail") {
     $('email' + this.id).innerHTML = "--";
    }
    if (this.action == "delmsg") {
     $('msg' + this.id).innerHTML = "--";
    }
    if (this.action == "del") {
     var url = getActionMappingURL("/subs?action=list&ajax=shtml&bid=" + this.bid + "&page=" + this.cpage);
     loadSubsListUrl(url);
    }
   }
   if (codeid == "1") {
    var url = getActionMappingURL("/subs?action=list&ajax=shtml&bid=" + this.bid + "&page=" + this.cpage);
    loadSubsListUrl(url);
    }
   }
};

public String delmsg() {
return this.dela("delmsg");
}

private String dela(String deltype) {
Subscibe subs = this.getSubscibeService().findSubscibeByID(this.getId(), this.getUserSession().getId(),
    this.getBid());
if (subs != null) {
   if (deltype.equalsIgnoreCase("delemail")) {
    subs.setEmailinform(0);
   }
   if (deltype.equalsIgnoreCase("delmsg")) {
    subs.setMsginform(0);
   }
   try {
    subs = this.getSubscibeService().saveSubscibe(subs);
    if (subs.getEmailinform() == 0 && subs.getMsginform() == 0) {
     this.getSubscibeService().removeSubscibe(subs);//两个都取消相当于remove!

this.getAjaxMessagesJson().setMessage("1", this.getText("subs.cancle.ok"));
} else {

     this.getAjaxMessagesJson().setMessage("0", this.getText("subs.cancle.ok"));
    }
   } catch (BbscsException ex) {
    this.getAjaxMessagesJson().setMessage("E_SUBS_CANCLE_ERROR", this.getText("error.subs.cancle.error"));
   }
} else {
   this.getAjaxMessagesJson().setMessage("E_SUBS_CANCLE_ERROR", this.getText("error.subs.cancle.error"));
}

return RESULT_AJAXJSON;
}

public String del() {//直接删除
try {
   this.getSubscibeService().removeSubscibe(this.getId(), this.getUserSession().getId(), this.getBid());
   this.getAjaxMessagesJson().setMessage("0", this.getText("subs.cancle.ok"));
} catch (BbscsException ex1) {
   this.getAjaxMessagesJson().setMessage("E_SUBS_CANCLE_ERROR", this.getText("error.subs.cancle.error"));
}
return RESULT_AJAXJSON;
}
