*****************************************

将会员列表改成按id排序（新注册用户排前面）

web-inf\config\database\generic\generic_queries.sql

将58-59行 "order by username" 改成 "order by user_id desc"

添加网站地图

-生成sitemap.xml
jforum 的url后缀是.page不是常规的.htm .html .asp .jsp 所以很多sitemap.xml builder不能识别jforum中的链接,所以自动生成不了sitemap.xml(本人猜想是这个原因),后来找半天找到一个工具叫SOFTplus GSiteCrawler的可以自定义页面后缀,从而自动生成sitemap.xml.

-添加国际化属性
zh_CN.properties中最后添加:mydwbi.sitemap=\u7f51\u7ad9\u5730\u56fe

-添加入口链接
在forum_list.htm中第181行下添加:


<td>&nbsp;&nbsp;</td>

<td align="center" width="20"><img   /></td>

<td><span class="gensmall"><a href="${contextPath}/sitemap.xml">${I18n.getMessage("mydwbi.sitemap")}</a></span></td>

修改版权信息

修改bottom.htm 11行.

将发贴时"poll","attachments","options"改成中文

-添加国际化属性
mydwbi.Options=\u9009\u9879
mydwbi.Poll=\u6295\u7968
mydwbi.Attach=\u9644\u4ef6

-修改模板
将post_form.htm中第369,372,375行"poll","attachments","options"改成:
${I18n.getMessage("mydwbi.Options")}
${I18n.getMessage("mydwbi.Poll")}
${I18n.getMessage("mydwbi.Attach")}

让发贴的表情符号列表多显示几个表情

修改post_form.htm261行，改成：<#if (count < 32)>

特定用户显示ip

post_show_user_inc.htm36，37行改成：


<#if (post.userIp?exists && isModerator) || (post.userIp?exists && session.username = "lynx286")>

${I18n.getMessage("PostShow.userIP")}: <a href="http://whois.domaintools.com/${post.userIp}"  target="_blank">${post.userIp}</a>

即如果当前登陆用户为该版版主或用户名为lynx286,就显示发贴人ip地址

进入板块后显示主题列表页面发表人栏显示帖子发表时间

进入板块后显示主题列表页面指： /forums/show/xxxx.page 页面
forum_show.htm页面224行改成：

<span class="postdetails">${topic.firstPostTime}<br />

<a href="${JForumContext.encodeURL("/user/profile/${topic.postedBy.id}")}">${topic.postedBy.username}</a></span>

176行改成：width=140

bmp图片也显示缩略图

用户经常用print screen键拷贝屏幕图片，并发到帖子上，是bmp格式，不能显示缩略图，要下载才能看，不太方便。这里改一下可显示缩略图。
AttachmentCommon.java 254行添加："bmp".equals(extension) ||

發表文章表單的國際化

針對發表文章時的國際化，我的處理方式是將新產生的語系key歸類為PostForm類別下，由於原本的PostForm.options已經存在，重複使用即可，故我們只需新增兩個新的key: PostForm.poll和PostForm.attachments
en_US.properties

PostForm.options= Options

PostForm.poll = Poll

PostForm.attachments = Attachments

zh_CN.properties

PostForm.options                = \u9009\u9879

PostForm.poll                   = \u6295\u7968

PostForm.attachments	        = \u9644\u4ef6

zh_TW.properties

PostForm.options                = \u9078\u9805

PostForm.poll                   = \u7968\u9078\u6D3B\u52D5

PostForm.attachments            = \u9644\u52A0\u6A94\u6848

接著將post_form.htm的:


							    <span>Options</span>



								<#if allowPoll>

									<span>Poll</span>

								</#if>

								<#if attachmentsEnabled>

								    <span>Attachments</span>

								</#if>

修改為：


							    <span>${I18n.getMessage("PostForm.options")}</span>



								<#if allowPoll>

									<span>${I18n.getMessage("PostForm.poll")}</span>

								</#if>

								<#if attachmentsEnabled>

								    <span>${I18n.getMessage("PostForm.attachments")}</span>

								</#if>

文章作者資訊顯示IP，並可超連結至whois.domaintools.com，取得詳細資訊

這邊我的處理方式是當使用者為版主或作者時顯示IP

<#if post.userIp?exists && (isModerator || post.userId == session.userId)>

	${I18n.getMessage("PostShow.userIP")}: ${post.userIp}

	


</#if>

将整个论坛页面宽度由满屏改为固定宽度

header.htm 31行： <table width="950" border="0" ALIGN="center">

将论坛跳转下拉框放到上面

post_show.htm 等页面 90 行，加上下面代码：


<td align="left">

					<span class="gensmall">${I18n.getMessage("ForumIndex.goTo")}:&nbsp;</span>

					<select onchange="if(this.options[this.selectedIndex].value != -1){ document.location = '${contextPath}/forums/show/'+ this.options[this.selectedIndex].value +'${extension}'; }" name="select">

						<option value="-1" selected="selected">${I18n.getMessage("ForumIndex.goToSelectAForum")}</option>				

						

						<#list allCategories as category>

                            <optgroup label="${category.name}">

		

							<#list category.getForums() as forum>

								<option value="${forum.id}">${forum.name}</option>

							</#list>

							</optgroup>

						</#list>

					</select>

					&nbsp;

					<input class="liteoption" type="button" value="${I18n.getMessage("ForumIndex.goToGo")}" onclick="if(document.f.select.options[document.f.select.selectedIndex].value != -1){ document.location = '${contextPath}/forums/show/'+ document.f.select.options[document.f.select.selectedIndex].value +'${extension}'; }" />

				  </td>

此段代码可以从 macros\presentaion.ftl 中 <#macro forumsComboTable> 里面拷贝。

讓一般使用者可以刪除自己發表的文章

1.打開權限：到系統管理控制台->群組管理->一般使用者->權限->可以刪除文章->是
2.修改templates/default/post_show_action_buttons_inc.htm裡面的22行：


<#if canRemove && (((post.userId == session.userId) && (session.userId != 1)) || isModerator || isAdmin)>

3.重新載入JForum即可。

让附件图片支持gif动画:
http://www.mydwbi.com/posts/list/470.page

AttachmentCommon.java:


private boolean shouldCreateThumb(Attachment a) {

		if (SystemGlobals

				.getBoolValue(ConfigKeys.ATTACHMENTS_IMAGES_CREATE_THUMB)) {

			String extension = a.getInfo().getExtension().getExtension()

					.toLowerCase();

			if (Attachment.isPicture(extension)) {

				String path = SystemGlobals

						.getValue(ConfigKeys.ATTACHMENTS_STORE_DIR)

						+ "/" + a.getInfo().getPhysicalFilename();

				File fileOriginal = new File(path);

				Image imageOriginal = null;

				try {

					imageOriginal = ImageIO.read(fileOriginal);

				} catch (IOException e) {

					e.printStackTrace();

				}

				int widthOriginal = imageOriginal.getWidth(null);

				int heightOriginal = imageOriginal.getHeight(null);

				if (widthOriginal > 800 || heightOriginal > 600)

					return true;

				else

					return false;

			} else

				return false;

		} else

			return false;

	}

Attachment.java:


public boolean hasThumb() {

		String pName = this.info.getPhysicalFilename();

		String extension = pName.substring(pName.lastIndexOf('.') + 1, pName

				.length() - 1);

		if (isPicture(extension)

				&& SystemGlobals

						.getBoolValue(ConfigKeys.ATTACHMENTS_IMAGES_CREATE_THUMB))

			return true;

		else

			return false;

	}



	public String thumbPath() {

		String fileDir = SystemGlobals

				.getValue(ConfigKeys.ATTACHMENTS_UPLOAD_DIR)

				+ '/' + this.info.getPhysicalFilename();

		String path = SystemGlobals.getValue(ConfigKeys.ATTACHMENTS_STORE_DIR)

				+ "/" + this.info.getPhysicalFilename();

		if (new File(path + "_thumb").exists()) {

			return fileDir + "_thumb";

		} else {

			return fileDir;

		}

	}



	public static boolean isPicture(String extension) {

		if ("bmp".equals(extension) || "jpg".equals(extension)

				|| "jpeg".equals(extension) || "gif".equals(extension)

				|| "png".equals(extension))

			return true;

		else

			return false;

	}

让头像也支持gif动画:
http://www.mydwbi.com/posts/list/471.page

UserCommon.java:


private static void handleAvatar(User u) {

		String fileName = MD5.crypt(Integer.toString(u.getId()));

		FileItem item = (FileItem) JForumExecutionContext.getRequest()

				.getObjectParameter("avatar");

		UploadUtils uploadUtils = new UploadUtils(item);



		// Gets file extension

		String extension = uploadUtils.getExtension().toLowerCase();

		int type = ImageUtils.IMAGE_UNKNOWN;

		if (extension.equals("jpg") || extension.equals("jpeg")) {

			type = ImageUtils.IMAGE_JPEG;

		} else if (extension.equals("gif")) {

			type = ImageUtils.IMAGE_GIF;

		} else if (extension.equals("png")) {

			type = ImageUtils.IMAGE_PNG;

		}



		if (type != ImageUtils.IMAGE_UNKNOWN) {

			String avatarFinalFileName = SystemGlobals.getApplicationPath()

					+ "/images/avatar/" + fileName + "." + extension;

			uploadUtils.saveUploadedFile(avatarFinalFileName);

			File avatar = new File(avatarFinalFileName);

			Image imageOriginal = null;

			try {

				imageOriginal = ImageIO.read(avatar);

			} catch (IOException e) {

				e.printStackTrace();

			}

			int widthOriginal = imageOriginal.getWidth(null);

			int heightOriginal = imageOriginal.getHeight(null);

			if (widthOriginal <= 130 && heightOriginal <= 130) {

				u.setAvatar(fileName + "." + extension);

			}else{

				avatar.delete();

			}

		}

	}

關於gif部分，我改良了一下lynx286的修改方式：
AttachmentCommon.java:
將最大寬度跟高度改為由系統參數檔設定


	private boolean shouldCreateThumb(Attachment a) {

		String extension = a.getInfo().getExtension().getExtension().toLowerCase();

		if (SystemGlobals.getBoolValue(ConfigKeys.ATTACHMENTS_IMAGES_CREATE_THUMB)

            && Attachment.isPicture(extension)) {

            String path = SystemGlobals.getValue(ConfigKeys.ATTACHMENTS_STORE_DIR)

			     + "/" 

			     + a.getInfo().getPhysicalFilename();

		    File imageFile = new File(path);

		    BufferedImage image = null;

		    try {

			    image = ImageIO.read(imageFile);

		    } catch (IOException e) {

			    e.printStackTrace();

		    }

		    int width = image.getWidth(null);

		    int height = image.getHeight(null);

		    return (width > SystemGlobals.getIntValue(ConfigKeys.ATTACHMENTS_IMAGES_MAX_THUMB_W) 

		        || height > SystemGlobals.getIntValue(ConfigKeys.ATTACHMENTS_IMAGES_MAX_THUMB_H));

        }

        return false;

	}

Attachment.java:
精簡一下程式碼


	public boolean hasThumb() 

	{

		String filename = this.info.getPhysicalFilename();

		String extension = filename.substring(filename.lastIndexOf('.') + 1, 

				filename.length() - 1);

		return SystemGlobals.getBoolValue(ConfigKeys.ATTACHMENTS_IMAGES_CREATE_THUMB)

			&& isPicture(extension);

	}

	

	public String thumbPath() {

		String urlPath = SystemGlobals.getValue(ConfigKeys.ATTACHMENTS_UPLOAD_DIR)

		    + '/' + this.info.getPhysicalFilename();

		String realPath = SystemGlobals.getValue(ConfigKeys.ATTACHMENTS_STORE_DIR)

		    + "/" + this.info.getPhysicalFilename();

		if (new File(realPath + "_thumb").exists()) {

			return urlPath + "_thumb";

		} else {

			return urlPath;

		}    

	}

	

	public static boolean isPicture(String extension) {

		return ("jpg".equals(extension) || "jpeg".equals(extension) 

				|| "gif".equals(extension) || "png".equals(extension)

				|| "bmp".equals(extension));

	}

UserCommon.java:
增加刪除舊的個人頭像，比對用的最大寬度跟高度調整為以系統設定值為準，及將過大的gif轉為png


	private static void handleAvatar(User u)

	{

		// Delete old avatar file

		if (u.getAvatar() != null) {

			File avatarFile = new File(u.getAvatar());

			

			File fileToDelete = new File(SystemGlobals.getApplicationPath() 

				+ "/images/avatar/"

				+ avatarFile.getName());

			

			if (fileToDelete.exists()) {

				fileToDelete.delete();

			}

		}

		

		String fileName = MD5.crypt(Integer.toString(u.getId()));

		FileItem item = (FileItem)JForumExecutionContext.getRequest().getObjectParameter("avatar");

		UploadUtils uploadUtils = new UploadUtils(item);

		

		// Gets file extension

		String extension = uploadUtils.getExtension().toLowerCase();

		int type = ImageUtils.IMAGE_UNKNOWN;

		

		if (extension.equals("jpg") || extension.equals("jpeg")) {

			type = ImageUtils.IMAGE_JPEG;

		} else if (extension.equals("gif")) {  

			type = ImageUtils.IMAGE_GIF;  

		} else if (extension.equals("png")) {  

			type = ImageUtils.IMAGE_PNG;  

		}

		

		if (type != ImageUtils.IMAGE_UNKNOWN) {

			String avatarTmpFileName = SystemGlobals.getApplicationPath() 

				+ "/images/avatar/" 

				+ fileName 

				+ "_tmp." 

				+ extension;

	

			String avatarFinalFileName = SystemGlobals.getApplicationPath() 

				+ "/images/avatar/" 

				+ fileName 

				+ "." 

				+ extension;

	

			uploadUtils.saveUploadedFile(avatarTmpFileName);		



			// OK, time to check and process the avatar size

			int maxWidth = SystemGlobals.getIntValue(ConfigKeys.AVATAR_MAX_WIDTH);

			int maxHeight = SystemGlobals.getIntValue(ConfigKeys.AVATAR_MAX_HEIGHT);



			File avatar = new File(avatarTmpFileName); 

			BufferedImage imageOriginal = null;

			try {

				imageOriginal = ImageIO.read(avatar);

			} catch (IOException e) {

				e.printStackTrace();

			}

			int width = imageOriginal.getWidth(null);

			int height = imageOriginal.getHeight(null);



			if (width > maxWidth || height > maxHeight) {				

				if (type == ImageUtils.IMAGE_GIF) {

					type = ImageUtils.IMAGE_PNG;

					extension = "png";

				}

				BufferedImage image = ImageUtils.resizeImage(avatarTmpFileName, type, maxWidth, maxHeight);				

				ImageUtils.saveImage(image, avatarFinalFileName, type);

				// Delete the temporary file

				avatar.delete();

			} else {

				avatar.renameTo(new File(avatarFinalFileName));

			}

			u.setAvatar(fileName + "." + extension);

		}

	}
