大家都知道了struts2 和fckEditor結合中為了上傳圖片
需要把
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
換掉
/*
但是在后來使用時發現標簽datetimepicker不能使用了
后來發現生成的頁面中有如下代碼
<link rel="stylesheet" href="/workStation/struts/xhtml/styles.css" type="text/css"/>
<script language="JavaScript" type="text/javascript">
// Dojo configuration
djConfig = {
baseRelativePath: "/workStation/struts/dojo",
isDebug: false,
bindEncoding: "gb2312",
debugAtAllCosts: true // not needed, but allows the Venkman debugger to work with the includes
};
</script>
<script language="JavaScript" type="text/javascript"
src="/workStation/struts/dojo/dojo.js"></script>
<script language="JavaScript" type="text/javascript"
src="/workStation/struts/simple/dojoRequire.js"></script>
所以就應加上
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/struts/*</url-pattern>
</filter-mapping>
要不然會找不到相應的js和css文件，大家遇到希望有幫助（結合時不要忘了在<head>中加入 <s:head />它會自動加上上面的代碼）

注意以下變量部分：
1.在MyConnector.java第42行的變量_actualServerPath 默認為值：/WEB-INF/classes/com/opensymphony/webwork/static/richtexteditor/data/,從源碼com.opensymphony.webwork.components.DefaultRichtexteditorConnector.java的第38行
Java代碼
protected String _actualServerPath = "/com/opensymphony/webwork/static/richtexteditor/data/";
protected String _actualServerPath = "/com/opensymphony/webwork/static/richtexteditor/data/";以及第51行
Java代碼
String path = "file:////"+servletContext.getRealPath("/WEB-INF/classes"+actualServerPath);
String path = "file:////"+servletContext.getRealPath("/WEB-INF/classes"+actualServerPath);
可以得出。
因此，我這里改成/user_file文件夾作為文件上傳路徑，你可以自由選擇。
2.在MyConnector.java第43行的變量_serverPath 表示的是上傳完附件后，選擇的路徑，默認為： /webwork/richtexteditor/data/。從源碼com.opensymphony.webwork.components.AbstractRichtexteditorConnector.java的第73行：
Java代碼
protected String _serverPath = "/webwork/richtexteditor/data/";
protected String _serverPath = "/webwork/richtexteditor/data/"; 可以看到。但FCKEditor使用時，會變成：http://IP地址/項目/webwork/richtexteditor/data/. 記住，這里不會帶端口號的，這也是唯一美中不足的地方，如果要修改，可能要改動很大了。
因此，我這里改成也/user_file文件夾，為了可以在上傳成功后，FCKEditor能夠選擇上傳成功的文件。
最后來到MyConnector.java 的第112行：
Java代碼
// TODO 非常重要的一句話，這樣才能使用自定義的路徑。
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(get_serverPath(), getCurrentFolder(), getType()));
// TODO 非常重要的一句話，這樣才能使用自定義的路徑。
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(get_serverPath(), getCurrentFolder(), getType()));
這里我詳細說一下：MyConnector.java 繼承自 AbstractRichtexteditorConnector.java，在AbstractRichtexteditorConnector.java源碼146行左右有這么一段：
Java代碼
else if ("CreateFolder".equals(getCommand())) {
_log.debug("Command "+getCommand()+" detected \n\t type="+getType()+"\n\t folderPath="+getCurrentFolder()+"\n\t newFolderName="+getNewFolderName());
ActionContext.getContext().put("__richtexteditorCommand", getCommand());
ActionContext.getContext().put("__richtexteditorType", getType());
ActionContext.getContext().put("__richtexteditorFolderPath", getCurrentFolder());
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(getServerPath(), getCurrentFolder(), getType()));
CreateFolderResult createFolderResult = createFolder(getCurrentFolder(), getType(), getNewFolderName());
ActionContext.getContext().put("__richtexteditorCreateFolder", createFolderResult);
return CREATE_FOLDER;
}
else if ("CreateFolder".equals(getCommand())) {
_log.debug("Command "+getCommand()+" detected \n\t type="+getType()+"\n\t folderPath="+getCurrentFolder()+"\n\t newFolderName="+getNewFolderName());
ActionContext.getContext().put("__richtexteditorCommand", getCommand());
ActionContext.getContext().put("__richtexteditorType", getType());
ActionContext.getContext().put("__richtexteditorFolderPath", getCurrentFolder());
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(getServerPath(), getCurrentFolder(), getType()));
CreateFolderResult createFolderResult = createFolder(getCurrentFolder(), getType(), getNewFolderName());
ActionContext.getContext().put("__richtexteditorCreateFolder", createFolderResult);
return CREATE_FOLDER;
}
在這段代碼的第7行，計算出的路徑永遠是父類里默認的 /webwork/richtexteditor/data/， 所以在它的子類MyConnector.java，我們重新賦值了一下： Java代碼
// TODO 非常重要的一句話，這樣才能使用自定義的路徑。
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(get_serverPath(), getCurrentFolder(), getType()));
// TODO 非常重要的一句話，這樣才能使用自定義的路徑。
ActionContext.getContext().put("__richtexteditorServerPath", calculateServerPath(get_serverPath(), getCurrentFolder(), getType()));
這樣，就能保證我們剛才定義的 user_file文件夾生效，文件通過FCKEditor上傳完后，通過服務器端瀏覽，可以看到我們上傳的圖片，然后點確定就可以了。不過，如果你不是默認的80端口，那么可能要手動改一改，真是有點遺憾。最后一步，也是最重要的一步，配置我們剛才寫的MyConnector.java
Xml代碼
<package name="richtexteditor-upload" extends="webwork-default"
namespace="/webwork/richtexteditor/editor/filemanager/upload">
<action name="uploader" class="com.leo.controller.MyConnector"
method="upload">

<result name="createFolder"
type="richtexteditorCreateFolder" />
<result name="fileUpload" type="richtexteditorFileUpload" />
</action>
</package>
一切完成，直接在JSP里調用即可：Html代碼
<ww:richtexteditor toolbarCanCollapse="true" width="700" label=""
name="txt" value="可以正常上傳了。" />
<ww:richtexteditor toolbarCanCollapse="true" width="700" label=""
name="txt" value="可以正常上傳了。" />
二 Struts2 + Dojo
Struts2部分更簡單了。雖然Struts2不直接支持FCKeditor，但直接Dojo，而且個人更喜歡這種簡潔的風格，我用的是Struts2.0.11版本進行測試，使用時，只要配置兩個地方
1. 在HTML<head />標簽之間，加上
Html代碼
<s:head theme="ajax"/>
<s:head theme="ajax"/>
2. 將textarea加上主題 Html代碼
<s:textarea theme="ajax" />
<s:textarea theme="ajax" />
就這么簡單。
