实现doc,ppt,txt等格式文件向可以在flexPaper中预览的翻页动画swf的格式转换,一般需要先把doc,ppt,txt等格式的文件先转换为pdf,然后再由pdf转换为swf才能实现在flexpaper中进行预览,实现类似百度豆丁的预览效果,其转换过程需要电脑安装 openoffice,swfTools软件,通过java代码:实现文档格式的转换,下面我将我在一个分布式项目中的一个文档预览部分的思路与大家共享:
1.安装openoffice,swfTools软件,配置好java代码的运行环境。
2.启动openOffice服务:
①、进入openoffice安装目录
cd opeonofiice的安装路径/program
②、启动端口监听
soffice -headless -accept="socket,host=127.0.0.1,port=8080;urp;" -nofirststartwizard
③、查看启动是否成功,存在8080端口即启动成功 netstat -an
3.在eclipse端运行以下java代码,实现文档的格式转换,并保存到
JodDemo.java:
public class JodDemo {
public static int convertPDF2SWF(String sourcePath, String destPath, String fileName) throws IOException {
//目标路径不存在则建立目标路径
File dest = new File(destPath);
if (!dest.exists()) dest.mkdirs();
//源文件不存在则返回
File source = new File(sourcePath);
if (!source.exists()) return 0;
//调用pdf2swf命令进行转换
String command = "D:\\SWFTools\\pdf2swf.exe" + " -o \"" + destPath + "\\" + fileName + "\" -s languagedir=D:\\xpdf\\xpdf-chinese-simplified -s flashversion=9 \"" + sourcePath + "\"";
Process pro = Runtime.getRuntime().exec(command);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(pro.getInputStream()));
while (bufferedReader.readLine() != null);
try {
pro.waitFor();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return pro.exitValue();
}
public static void main(String []args) throws IOException {
String a = "世界各地国庆节";
String sourcePath = "d:\\"+a+".pdf";
String destPath = "d:\\swf\\";
String fileName = a+".swf";
JodDemo.convertPDF2SWF(sourcePath, destPath, fileName);
}
}
Office2Pdf.java
public class Office2Pdf {
public static void main(String[] args) throws Exception {
String a = "世界各地国庆节";
off2Pdf(a);
}
public static void off2Pdf(String fileName) {
File inputFile = new File("d:/" + fileName + ".ppt");
File outputFile = new File("d:/" + fileName + ".pdf");
// connect to an OpenOffice.org instance running on port 8100
OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
try {
connection.connect();
} catch (ConnectException e) {
e.printStackTrace();
}
// convert
DocumentConverter converter = new OpenOfficeDocumentConverter(
connection);
converter.convert(inputFile, outputFile);
connection.disconnect();
}
}
Pdf2Swf.java
public class Pdf2Swf {
//实现由pdf格式到swf格式的转换
public int convertPDF2SWF(String sourcePath, String destPath,
String fileName) throws IOException {
// 目标路径不存在则建立目标路径
File dest = new File(destPath);
if (!dest.exists()) {
dest.mkdirs();
}
// 源文件不存在则返回
File source = new File(sourcePath);
if (!source.exists()) {
return 0;
}
String[] envp = new String[1];
envp[0] = "PATH=D:\\SWFTools\\";
String command = "pdf2swf -z -s flashversion=9 \"" + sourcePath
+ "\" -o \"" + destPath + fileName + "\"";
Process pro = Runtime.getRuntime().exec(command, envp);
// System.out.println(command);
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(pro.getInputStream()));
while (bufferedReader.readLine() != null) {
String text = bufferedReader.readLine();
System.out.println(text);
}
try {
pro.waitFor();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// 然后在套播放器
command = "swfcombine -z -X 720 -Y 540 \"D:/SWFTools/swfs/rfxview.swf\" viewport=\""
+ destPath + fileName + "\" -o \"" + destPath + fileName + "\"";
pro = Runtime.getRuntime().exec(command, envp);
System.out.println(command);
bufferedReader = new BufferedReader(new InputStreamReader(pro
.getInputStream()));
while (bufferedReader.readLine() != null) {
String text = bufferedReader.readLine();
System.out.println(text);
}
try {
pro.waitFor();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return pro.exitValue();
}
public static void main(String[] args) {
String sourcePath = "d:/document.pdf";
String destPath = "d:/";
String fileName = "document.swf";
try {
System.out.println(new Pdf2Swf().convertPDF2SWF(sourcePath,
destPath, fileName));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
代码已经在MyEclipse上运行测试无误,可以实现将本地文件实现格式转换,
4.注意:注意代码中加载各个软件的本地路径要正确,防止加载不到软件而报错
在代码运行前要启动openoffice服务,否则不能完成文件格式的转换
