默认的不能正常管理文件

先说怎么做,再稍微解释一下为什么这么做
1.webwork.properties里面设置
webwork.serve.static=false
webwork.multipart.parser=cos
2. 在webapp的根目录下建一个文件夹webwork,把webwork.jar里面的 /com/opensymphony/webwork/static和/template里面的文件和复制到自己建的webwork文件夹里面,在 /webwork/richtexteditor里面建文件夹data(可能会自动建,没测试过)
3.写一个RichtexteditorConnector
[code:1]
package test;

import java.io.FileFilter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.ServletContext;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.opensymphony.webwork.components.DefaultRichtexteditorConnector;


public class RichtexteditorConnector extends DefaultRichtexteditorConnector {
    public static final Log _log = LogFactory
            .getLog(RichtexteditorConnector.class);

    private ServletContext servletContext;

    public void setServletContext(ServletContext servletContext) {
        this.servletContext = servletContext;
    }

    protected String calculateActualServerPath(String actualServerPath,
            String type, String folderPath) throws Exception {
        String path = servletContext.getRealPath(actualServerPath);
        path = path.replace('\\', '/');
        makeDirIfNotExists(path);
        path = path.endsWith("/") ? path : path + "/";
        return path + type + folderPath;
    }

    protected Folder[] getFolders(String virtualFolderPath, String type)
            throws Exception {
        String path = calculateActualServerPath(getActualServerPath(), type,
                virtualFolderPath);
        makeDirIfNotExists(path);
        java.io.File f = new java.io.File(path);
        java.io.File[] children = f.listFiles(new FileFilter() {
            public boolean accept(java.io.File pathname) {
                if (!pathname.isFile()) {
                    return true;
                }
                return false;
            }
        });

        List tmpFolders = new ArrayList();
        for (int a = 0; a < children.length; a++) {
            tmpFolders.add(new Folder(children[a].getName()));
        }

        return (Folder[]) tmpFolders.toArray(new Folder[0]);
    }

    protected FoldersAndFiles getFoldersAndFiles(String virtualFolderPath,
            String type) throws Exception {
        String path = calculateActualServerPath(getActualServerPath(), type,
                virtualFolderPath);
        makeDirIfNotExists(path);
        java.io.File f = new java.io.File(path);
        java.io.File[] children = f.listFiles();

        List directories = new ArrayList();
        List files = new ArrayList();
        for (int a = 0; a < children.length; a++) {
            if (children[a].isDirectory()) {
                directories.add(new Folder(children[a].getName()));
            } else {
                try {
                    files.add(new File(children[a].getName(),
                            fileSizeInKBytes(children[a])));
                } catch (Exception e) {
                    _log.error("cannot deal with file " + children[a], e);
                }
            }
        }

        return new FoldersAndFiles((Folder[]) directories
                .toArray(new Folder[0]), (File[]) files.toArray(new File[0]));
    }

    protected FileUploadResult fileUpload(String virtualFolderPath,
            String type, String filename, String contentType,
            java.io.File newFile) {
        try {
            String tmpDir = calculateActualServerPath(getActualServerPath(),
                    type, virtualFolderPath);
            makeDirIfNotExists(tmpDir);
            String tmpFile = tmpDir + filename;
            if (makeFileIfNotExists(tmpFile)) {
                // already exists
                int a = 0;
                String ext = String.valueOf(a);
                tmpFile = calculateActualServerPath(getActualServerPath(),
                        type, virtualFolderPath)
                        + filename + ext;
                while (makeFileIfNotExists(tmpFile)) {
                    a = a + 1;
                    ext = String.valueOf(a);
                    if (a > 100) {
                        return FileUploadResult.invalidFile();
                    }
                }
                copyFile(newFile, new java.io.File(tmpFile));
                return FileUploadResult
                        .uploadCompleteWithFilenamChanged(filename + ext);
            } else {
                copyFile(newFile, new java.io.File(tmpFile));
                return FileUploadResult.uploadComplete();
            }
        } catch (Exception e) {
            _log.error(e.toString(), e);
            e.printStackTrace();
            return FileUploadResult.invalidFile();
        }
    }

    protected void unknownCommand(String command, String virtualFolderPath,
            String type, String filename, String contentType,
            java.io.File newFile) {
        throw new RuntimeException("unknown command " + command);
    }

    /**
     *
     * @param path
     * @return true if file already exists, false otherwise.
     */
    protected boolean makeDirIfNotExists(String path) {
        java.io.File dir = new java.io.File(path);
        if (!dir.exists()) {
            _log.debug("make directory " + dir);
            boolean ok = dir.mkdirs();
            if (!ok) {
                throw new RuntimeException("cannot make directory " + dir);
            }
            return false;
        }
        return true;
    }

    protected boolean makeFileIfNotExists(String filePath) throws IOException {
        java.io.File f = new java.io.File(filePath);
        if (!f.exists()) {
            _log.debug("creating file " + filePath);
            boolean ok = f.createNewFile();
            if (!ok) {
                throw new RuntimeException("cannot create file " + filePath);
            }
            return false;
        }
        return true;
    }

}
[/code:1]
4.xwork.xml加上
[code:1]
<package name="richtexteditor-browse" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/browser/default/connectors/jsp">
        <action name="connector"
            class="test.RichtexteditorConnector"
            method="browse">
            <param name="actualServerPath">
                /webwork/richtexteditor/data
            </param>
            <result name="getFolders" type="richtexteditorGetFolders" />
            <result name="getFoldersAndFiles"
                type="richtexteditorGetFoldersAndFiles" />
            <result name="createFolder"
                type="richtexteditorCreateFolder" />
            <result name="fileUpload" type="richtexteditorFileUpload" />
        </action>
</package>
<package name="richtexteditor-upload" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/upload">
        <action name="uploader"
            class="test.RichtexteditorConnector"
            method="upload">
            <param name="actualServerPath">
                /webwork/richtexteditor/data
            </param>
            <result name="richtexteditorFileUpload" />
        </action>
</package>
[/code:1]
5.配置标签
[code:1]
<ww:form action="test" method="post">
    <%request.setAttribute("contextPath",request.getContextPath());%>
    <ww:richtexteditor basePath="%{#request.contextPath}/webwork/richtexteditor/"         toolbarCanCollapse="false" width="700" label="description" name="content" defaultLanguage="zh-cn" />
    <ww:submit value="submit" />
</ww:form>
[/code:1]
6.服务器端口设置为80

原因
1.
webwork.serve.static=false
/webwork/*这样的URL是可以直接访问不需要通过webwork,这样做是为了自己可以在里面建文件,并且可以方便的访问这些文件
webwork.multipart.parser=cos
设置为jakarta上传文件不成功, com.opensymphony.webwork.interceptor.FileUploadInterceptor解析 MultiPartRequestWrapper不成功,原因不清楚,反正用cos就可以了,记得加上cos.jar
2.因为设置了webwork.serve.static=false需要这样做
3. 覆盖webwork的DefaultRichtexteditorConnector,最关键的是覆盖 calculateActualServerPath()方法,默认是把文件放到/WEB- INF/classes/com/opensymphony/webwork/static/richtexteditor/data/,我们需要放到 /webwork/richtexteditor/data/里面,覆盖其他方法是因为默认对文件的访问都是通过
new File(new URI("file://"+filePath);来访问的,会有些问题,直接new File(filePath)就可以了
4.使用自己的RichtexteditorConnector,并且设置参数actualServerPath,其他参数不要改,webwork默认的是这样
5.basePath 必须自己指定不能用默认的,虽然指定的值和默认的是一样,但是不自己指定的话它自动加上jsessionid,如 /webwork/richtexteditor/;jsessionid=301gs94034pki/editor/fckeditor.html, 因为设置了webwork.serve.static=false,所以服务器不能解析这个url
defaultLanguage="zh-cn",不指定的话中文默认是繁体
6.服务器端口必须为80不能为8080,因为fckeditor链接你上传的文件的时候,不会把端口加上去

在FireFox下面用不了富文本编辑。我的版本是1.5。这就够郁闷的了

FCK Editor在FF1.5和1.0下应该可以工作的,我们的项目可以。不过我们没有用Webwork 2.2.2的方式,是直接用FCK Editor,感觉查不多的。

楼主能不能提供一个用富文本编辑器上传文件的例子啊?我这崩溃了,webwork自带的也没有啊,帮助中只讲了些方法,不实用啊
