flexpaper仿百度文库实现在线阅读

准备工作

下载openoffice：

http://www.openoffice.org/download/index.html

下载swftools：

http://www.swftools.org/download.html 

只用到pdf2swf.exe

  以上安装文件要注意一点：安装目录避免带有空格

  用openoffice将office文档生成pdf

  /**

* office文档转pdf文件

* @param sourceFileoffice文档绝对路径

* @param destFilepdf文件绝对路径

* @return

*/

private int office2PDF(String sourceFile, String destFile) {

ResourceBundle rb = ResourceBundle.getBundle("OpenOfficeService");

String OpenOffice_HOME = rb.getString("OO_HOME");

String host_Str = rb.getString("oo_host");

String port_Str = rb.getString("oo_port");

try {

File inputFile = new File(sourceFile);

if (!inputFile.exists()) {

return -1; // 找不到源文件 

}

// 如果目标路径不存在, 则新建该路径  

File outputFile = new File(destFile);

if (!outputFile.getParentFile().exists()) {

outputFile.getParentFile().mkdirs();

}

// 启动OpenOffice的服务  

String command = OpenOffice_HOME

+ "/program/soffice.exe -headless -accept=\"socket,host="

+ host_Str + ",port=" + port_Str + ";urp;-nofirststartwizard &\"";

System.out.println("###\n" + command);

Process pro = Runtime.getRuntime().exec(command);

// 连接openoffice服务

OpenOfficeConnection connection = new SocketOpenOfficeConnection(

host_Str, Integer.parseInt(port_Str));

connection.connect();

// 转换 

DocumentConverter converter = new OpenOfficeDocumentConverter(

connection);

System.out.println("inputFile:" + inputFile);

System.out.println("outputFile:" + outputFile);

converter.convert(inputFile, outputFile);

// 关闭连接和服务

connection.disconnect();

pro.destroy();

return 0;

} catch (FileNotFoundException e) {

System.out.println("文件未找到！");

e.printStackTrace();

return -1;

} catch (ConnectException e) {

System.out.println("OpenOffice服务监听异常！");

e.printStackTrace();

boolean flag = true;

System.out.println("sourceFile------" + sourceFile);

File srcFile = new File(sourceFile);

if (!srcFile.exists()) {

return -1; // 找不到源文件 

}

System.out.println("<><><>" + srcFile.getName());

int fileLen = srcFile.getName().length();

String excPath = sourceFile.substring(0, sourceFile.length()-fileLen-1);

if(flag){

beginConvert(excPath,"",srcFile.getName());

flag = false;

}

} catch (IOException e) {

e.printStackTrace();

}

return 1;

}

  将pdf文件转换成swf文件

  private void convertPdf2Swf(String sourceFile, String outFile,

String toolFile) {

// -s languagedir=D:\\xpdf-chinese-simplified  用于处理pdf转换swf中文乱码问题

String command = toolFile + " \"" + sourceFile + "\" -o  \"" + outFile

+ "\" -s flashversion=9 -s languagedir=D:\\xpdf-chinese-simplified";

if("Linux".equals(props.getProperty("os.name"))){

command = "/usr/bin/pdf2swf" + " " + sourceFile + " -o  " + outFile

+ " -s flashversion=9 ";

}

System.out.println("<><><>" + command);

try {

Process process = Runtime.getRuntime().exec(command);

System.out.println("1--" + loadStream(process.getInputStream()));

System.err.println("2--" + loadStream(process.getErrorStream()));

System.out.println("3--" + loadStream(process.getInputStream()));

System.out.println("###--Msg: swf 转换成功");

} catch (Exception e) {

e.printStackTrace();

}

}

入口方法-通过此方法转换文件至swf格式

/**

* 入口方法-通过此方法转换文件至swf格式

* @param filePath上传文件所在文件夹的绝对路径

* @param dirPath文件夹名称

* @param fileName文件名称

* @return生成swf文件名

*/

public String beginConvert(String filePath, String dirName, String fileName) {

final String DOC = ".doc";

final String DOCX = ".docx";

final String XLS = ".xls";

final String XLSX = ".xlsx";

final String PDF = ".pdf";

final String SWF = ".swf";

final String TXT = ".txt";

final String ODT = ".odt";

final String PPT = ".ppt";

final String PPTX = ".pptx";

final String TOOL = "pdf2swf.exe";

String outFile = "";

String fileNameOnly = "";

String fileExt = "";

if (null != fileName && fileName.indexOf(".") > 0) {

int index = fileName.lastIndexOf(".");

fileNameOnly = fileName.substring(0, index);

fileExt = fileName.substring(index).toLowerCase();

}

String inputFile = filePath +File.separator+ fileName;

String outputFile = "";

String supportingFilePath = filePath +"(support)";

File file = new File(supportingFilePath);

if(!file.exists()){

file.mkdirs();

}

//如果是txt文档，先转为pdf文件

if(fileExt.equals(TXT)){

File docFile = new File(filePath +File.separator+ fileName);

File odtFile = new File(supportingFilePath +File.separator+fileNameOnly+ODT);

try {

FileUtil.copyFile(docFile, odtFile);

} catch (IOException e) {

e.printStackTrace();

}

inputFile = supportingFilePath +File.separator+fileNameOnly+ODT;

fileExt = ODT;

}

//如果是office文档，先转为odt文件

if (fileExt.equals(DOC) || fileExt.equals(DOCX) || fileExt.equals(XLS)

|| fileExt.equals(XLSX)|| fileExt.equals(ODT)|| fileExt.equals(PPT)

|| fileExt.equals(PPTX)) {

outputFile = supportingFilePath +File.separator+ fileNameOnly + PDF;

office2PDF(inputFile, outputFile);

inputFile = outputFile;

fileExt = PDF;

}

if (fileExt.equals(PDF)) {

String toolFile = propertyContext +"2/" + TOOL;

outputFile = supportingFilePath +File.separator+ fileNameOnly + SWF;

convertPdf2Swf(inputFile, outputFile, toolFile);

outFile = outputFile;

}

return outFile;

}

还有就是调用flexpaperviewer

var fp = new FlexPaperViewer(  

              'FlexPaperViewer',

              'viewerPlaceHolder', { config : {

              SwfFile :encodeURI('<%=basePath%>ueditor/jsp/<%=filePath%>'),

              Scale : 1,

              ZoomTransition : 'easeOut',

              ZoomTime : 0.5,

              ZoomInterval : 0.2,

              FitPageOnLoad : true,

              FitWidthOnLoad : true,

              PrintEnabled : false,

              FullScreenAsMaxWindow : true,

              ProgressiveLoading : true,

              MinZoomSize : 0.2,

              MaxZoomSize : 1,

              SearchMatchAll : true,

              InitViewMode : 'Portrait',

              PrintPaperAsBitmap : false,

              PrintToolsVisible : false,

              ViewModeToolsVisible : true,

              ZoomToolsVisible : false,

              NavToolsVisible : false,

              CursorToolsVisible : true,

              SearchToolsVisible : true,                        

              localeChain: 'zh_CN'

              }});
