java将常用办公文档转swf.docx

java调用flashpaper实现文档转换为swf1，使用线程挂起使java线程与外部程序进程保持同步2，利用文件大小，调度java线程，提高运行效率3，可以以队列的方式实现连续转换文件 4，转换后的swf可能与某些预览方式不兼容，最后作者贴出了jsp预览代码5，本文贴出了大部分的代码，旨在表达作者实现的思想，可能不能立即调试通过，请自行修改。6，QQ：136677364 非常欢迎和大家交流package com.liuzizhong.convert2swf;import java.io.File;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.Map;import java.util.logging.Logger;import mon.FormatUtil;import mon.ProjectConfig;/* * 文件转换swf格式支持 * * author LiuZizhong * version 2013-12-19 */public class Convert2SwfProcess private Logger logger;private ProcessBuilder proBuilder;private ProjectConfig config = ProjectConfig.getInstance();/* * 构造方法 */public Convert2SwfProcess()super();logger = Logger.getLogger(Convert2SwfProcess.class.getName();/初始化进程生成器initProcessBuilder();/* * 转换文件，参数都是绝对路径 * * param inFile 要转换的文件的绝对路径 * param outFolder 输出文件的绝对路径 * return * throws Convert2SwfException * throws UnSupportExtException */public String convertFile(File inFile, File outFolder) throws Convert2SwfException, UnSupportExtException if(!outFolder.isDirectory()throw new Convert2SwfException(输出文件路径不合法！+outFolder.getAbsolutePath();if(!inFile.isFile()throw new Convert2SwfException(待转换的文件路径不合法！+inFile.getAbsolutePath();/判断文件格式是否能转String arr = inFile.getName().split(.);String ext = arrarr.length-1;if(!FormatUtil.getInstance().isConvertFormat(ext)throw new UnSupportExtException(不支持+ext+类型的文件!+inFile.getAbsolutePath();/过大的文件可下载预览，转换没意义long fileLength = inFile.length();if(fileLength(1024*1204*config.getConvertMaxSize()throw new Convert2SwfException(文件大于+config.getConvertMaxSize()+M!+inFile.getAbsolutePath();/ 设置输出文件名称和路径String tmpOutFile = outFolder.getPath().concat(File.separator).concat(inFile.getName().replaceAll(.1.*$, .swf);/ 如果转换后的文件已经存在，(删除该文件重转,或者是抛出异常），（应该在数据库中控制已经转完的不再转)File outFile1 = new File(tmpOutFile);if(outFile1.exists()/outFile1.delete();throw new Convert2SwfException(swf文件已经存在!+tmpOutFile);/ 拼接要执行的命令（命令路径中有空格，使用list传递)List commandArray = new ArrayList();commandArray.add(config.getConvertCommand();commandArray.add(inFile.getPath();commandArray.add(-o);commandArray.add(tmpOutFile);/根据文件的大小设置等待时间long waitTime = config.getConvertBaseWaitTime()*1000;if(fileLength1024*1024)/小于1M 3秒+每兆1秒waitTime += inFile.length()/1000;else if(fileLength(start+1000*60*config.getConvertBreakTime()throw new Convert2SwfException(转换超时,强行终止!+inFile.getAbsolutePath();try Thread.sleep(100); catch (InterruptedException e) e.printStackTrace();/* * 将命令交给dos命令行处理，并让线程等待waitTime * * param pb ProcessBuilder对象 * param cmd 要执行的命令 * param waitTime 进程等待时间 * throws Convert2SwfException */private int executeCommand(ProcessBuilder pb, List cmd,long waitTime) throws Convert2SwfException int result;try Process pro = mand(cmd).start();result = pro.waitFor();pro.destroy();(正在转换.);Thread.sleep(waitTime);return result; catch (IOException e) throw new Convert2SwfException(执行命令： + cmd + 失败！ + e); catch (InterruptedException e) (Process.waitFor被中断! + e);return 500;/* * 初始化ProcessBuilder对象 */private void initProcessBuilder() / 创建ProcessBuilder对象，传入参数proBuilder = new ProcessBuilder();Map envMap = proBuilder.environment();envMap.clear();envMap.putAll(System.getenv();/proBuilder.directory(工作路径);proBuilder.redirectErrorStream(true);package mon;import java.util.ArrayList;import java.util.List;public class FormatUtil private List convertFormats = new ArrayList();private FormatUtil() convertFormats.add(doc);convertFormats.add(docx);convertFormats.add(xls);convertFormats.add(xlsx);convertFormats.add(ppt);convertFormats.add(pdf);convertFormats.add(txt);public boolean isConvertFormat(String extendName) return convertFormats.contains(extendName);public static FormatUtil fu = new FormatUtil();public static FormatUtil getInstance() return fu;package mon;import java.util.ResourceBundle;public class ProjectConfig private int uploadFileMaxSize;private int convertMaxSize = 50;private int convertBaseWaitTime = 3;private int convertBreakTime = 1;private String convertCommand;private ProjectConfig() ResourceBundle bundle = ResourceBundle.getBundle(config);uploadFileMaxSize = Integer.parseInt(0+bundle.getString(UploadFileMaxSize).replace( ,);convertCommand = bundle.getString(ConvertCommand);public int getUploadFileMaxSize()return uploadFileMaxSize;public int getConvertMaxSize()return convertMaxSize;public int getConvertBaseWaitTime()return convertBaseWaitTime;public int getConvertBreakTime()return convertBreakTime;public String getConvertCommand()return convertCommand;private static ProjectConfig config = new ProjectConfig();public static ProjectConfig getInstance() return config;下面是配置文件perties#FlashPaper command pathConvertCommand=C:ProgramFilesMacr
