struts2实现ckeditor中的文件上传
页面很简单：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>editor</title>
	<script type="text/javascript" src="resource/ckeditor/ckeditor.js"></script>	
  </head>
  
  <body>
    	<textarea id="test"></textarea>
    	<script>
    		CKEDITOR.replace("test",{
    			filebrowserUploadUrl : 'ckeditor/ckupload.action'
        	});
    	</script>
  </body>
</html>


因为ckeditor默认上传文件的字段为upload
所在Action中的字段应为：
upload，uploadContentType，uploadFileName
为什么是这三个字段，大家应该都清楚的吧。

package com.zenntou.test.action;


import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;

public class CkeditorUploadAction extends ActionSupport {

	private String uploadContentType;
	
	private String uploadFileName;
	
	private String CKEditorFuncNum;
	
	private String CKEditor;
	
	private String langCode;
	
	private File upload;
	
	/**
	 * @return the upload
	 */
	public File getUpload() {
		return upload;
	}

	/**
	 * @param upload the upload to set
	 */
	public void setUpload(File upload) {
		this.upload = upload;
	}

	/**
	 * @return the cKEditorFuncNum
	 */
	public String getCKEditorFuncNum() {
		return CKEditorFuncNum;
	}

	/**
	 * @param cKEditorFuncNum the cKEditorFuncNum to set
	 */
	public void setCKEditorFuncNum(String cKEditorFuncNum) {
		CKEditorFuncNum = cKEditorFuncNum;
	}

	/**
	 * @return the cKEditor
	 */
	public String getCKEditor() {
		return CKEditor;
	}

	/**
	 * @param cKEditor the cKEditor to set
	 */
	public void setCKEditor(String cKEditor) {
		CKEditor = cKEditor;
	}

	/**
	 * @return the langCode
	 */
	public String getLangCode() {
		return langCode;
	}

	/**
	 * @param langCode the langCode to set
	 */
	public void setLangCode(String langCode) {
		this.langCode = langCode;
	}

	/**
	 * @return the uploadContentType
	 */
	public String getUploadContentType() {
		return uploadContentType;
	}

	/**
	 * @param uploadContentType the uploadContentType to set
	 */
	public void setUploadContentType(String uploadContentType) {
		this.uploadContentType = uploadContentType;
	}

	/**
	 * @return the uploadFileName
	 */
	public String getUploadFileName() {
		return uploadFileName;
	}

	/**
	 * @param uploadFileName the uploadFileName to set
	 */
	public void setUploadFileName(String uploadFileName) {
		this.uploadFileName = uploadFileName;
	}

	@Override
	public String execute() throws Exception {
		String strPath = ServletActionContext.getServletContext().getRealPath("/uploads");
		File path = new File(strPath);
		if(!path.exists()){
			path.mkdirs();
		}
		//FileImageInputStream is = new FileImageInputStream(this.upload);
		//FileImageOutputStream os = new FileImageOutputStream(new File(strPath + File.separator + this.uploadFileName));
		InputStream is = new FileInputStream(this.upload);
		OutputStream os = new FileOutputStream(new File(strPath + File.separator + this.uploadFileName));
		
		try {

			int len;
			byte[] buffer = new byte[1024];
			while ((len=is.read(buffer)) > 0) {
				os.write(buffer,0,len);
			}
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if(is!=null){
				is.close();
			}
			if(os!=null){
				os.close();
			}
		}
		PrintWriter out = ServletActionContext.getResponse().getWriter();
		//返回给ckeditor
		out.write("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("+this.CKEditorFuncNum+", 'uploads/" + this.uploadFileName+"', '');</script>");
		return Action.NONE;
	}
}


因为要上传文件，所以要配置一下struts.multipart.saveDir
有两种方法：
在struts.xml配置文件里添加：
<constant name="struts.multipart.saveDir" value="d:\\temp"></constant>

或者
在src根目录添加struts.properties文件（如果还没有的话），
添加struts.multipart.saveDir = d:\\temp 一行内容


虽然比较简单，希望能给大家带来一定的帮助！
