一、使用Jacob转换Word,Excel为HTML
癑ACOB一个Java-COM中间件.通过这个组件你可以在Java应用程序中调用COM组件和Win32 libraries。”
紫认略豃acob包,JDK1.5以上需要使用Jacob1.9版本(JDK1.6尚未测试),与先前的Jacob1.7差别不大
、将压缩包解压后,Jacob.jar添加到Libraries中;
、将Jacob.dll放至“WINDOWS\SYSTEM32”下面。
需要注意的是:
【使用IDE启动Web服务器时,系统读取不到Jacob.dll,例如用MyEclipse启动Tomcat,就需要将dll文件copy到MyEclipse安装目录的“jre\bin”下面。
一般系统没有加载到Jacob.dll文件时,报错信息为:“java.lang.UnsatisfiedLinkError: no jacob in java.library.path”】
新建类:
public class JacobUtil
{
public static final int WORD_HTML = 8;
public static final int WORD_TXT = 7;
public static final int EXCEL_HTML = 44;
/**
* WORD转HTML
* @param docfile WORD文件全路径
* @param htmlfile 转换后HTML存放路径
*/
public static void wordToHtml(String docfile, String htmlfile)
{
ActiveXComponent app = new ActiveXComponent("Word.Application"); // 启动word
try
{
app.setProperty("Visible", new Variant(false));
Dispatch docs = app.getProperty("Documents").toDispatch();
Dispatch doc = Dispatch.invoke(
docs,
"Open",
Dispatch.Method,
new Object[] { docfile, new Variant(false),
new Variant(true) }, new int[1]).toDispatch();
Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {
htmlfile, new Variant(WORD_HTML) }, new int[1]);
Variant f = new Variant(false);
Dispatch.call(doc, "Close", f);
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
app.invoke("Quit", new Variant[] {});
}
}
/**
* EXCEL转HTML
* @param xlsfile EXCEL文件全路径
* @param htmlfile 转换后HTML存放路径
*/
public static void excelToHtml(String xlsfile, String htmlfile)
{
ActiveXComponent app = new ActiveXComponent("Excel.Application"); // 启动word
try
{
app.setProperty("Visible", new Variant(false));
Dispatch excels = app.getProperty("Workbooks").toDispatch();
Dispatch excel = Dispatch.invoke(
excels,
"Open",
Dispatch.Method,
new Object[] { xlsfile, new Variant(false),
new Variant(true) }, new int[1]).toDispatch();
Dispatch.invoke(excel, "SaveAs", Dispatch.Method, new Object[] {
htmlfile, new Variant(EXCEL_HTML) }, new int[1]);
Variant f = new Variant(false);
Dispatch.call(excel, "Close", f);
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
app.invoke("Quit", new Variant[] {});
}
}
}
public class JacobUtil
{
public static final int WORD_HTML = 8;
public static final int WORD_TXT = 7;
public static final int EXCEL_HTML = 44;
/**
* WORD转HTML
* @param docfile WORD文件全路径
. * @param htmlfile 转换后HTML存放路径
. */
. public static void wordToHtml(String docfile, String htmlfile)
. {
. ActiveXComponent app = new ActiveXComponent("Word.Application"); // 启动word
. try
. {
. app.setProperty("Visible", new Variant(false));
. Dispatch docs = app.getProperty("Documents").toDispatch();
. Dispatch doc = Dispatch.invoke(
. docs,
. "Open",
. Dispatch.Method,
. new Object[] { docfile, new Variant(false),
. new Variant(true) }, new int[1]).toDispatch();
. Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {
. htmlfile, new Variant(WORD_HTML) }, new int[1]);
. Variant f = new Variant(false);
. Dispatch.call(doc, "Close", f);
. }
. catch (Exception e)
. {
. e.printStackTrace();
. }
. finally
. {
. app.invoke("Quit", new Variant[] {});
. }
. }
. /**
. * EXCEL转HTML
. * @param xlsfile EXCEL文件全路径
. * @param htmlfile 转换后HTML存放路径
. */
. public static void excelToHtml(String xlsfile, String htmlfile)
. {
. ActiveXComponent app = new ActiveXComponent("Excel.Application"); // 启动word
. try
. {
. app.setProperty("Visible", new Variant(false));
. Dispatch excels = app.getProperty("Workbooks").toDispatch();
. Dispatch excel = Dispatch.invoke(

. Dispatch.invoke(excel, "SaveAs", Dispatch.Method, new Object[] {

. Variant f = new Variant(false);
. Dispatch.call(excel, "Close", f);
. }
. catch (Exception e)
. {
. e.printStackTrace();
. }
. finally
. {
. app.invoke("Quit", new Variant[] {});
. }
. }
.}
.当时我在找转换控件时,发现网易也转载了一偏关于Jacob使用帮助,但其中出现了比较严重的错误:String htmlfile = "C:\\AA";
.只指定到了文件夹一级,正确写法是String htmlfile = "C:\\AA\\xxx.html";
.到此WORD/EXCEL转换HTML就已经差不多了,相信大家应该很清楚了:)
.二、使用XPDF将PDF转换为HTML
.1、下载xpdf最新版本,地址:http://www.foolabs.com/xpdf/download.html
.我下载的是xpdf-3.02pl2-win32.zip
.2、下载中文支持包
.我下载的是xpdf-chinese-simplified.tar.gz
.3、下载pdftohtml支持包
.地址:http://sourceforge.net/projects/pdftohtml/
.我下载的是:pdftohtml-0.39-win32.tar.gz
.4、解压调试
.1) 先将xpdf-3.02pl2-win32.zip解压,解压后的内容可根据需要进行删减,如果只需要转换为txt格式,其他的exe文件可以删除,只保留pdftotext.exe,以此类推;
.2) 然后将xpdf-chinese-simplified.tar.gz解压到刚才xpdf-3.02pl2-win32.zip的解压目录;
.3) 将pdftohtml-0.39-win32.tar.gz解压,pdftohtml.exe解压到xpdf-3.02pl2-win32.zip的解压目录;
.4) 目录结构:
. +---[X:\xpdf]
. |-------各种转换用到的exe文件
. |
. |-------xpdfrc
. |
. +------[X:\xpdf\xpdf-chinese-simplified]
. |
. |
. +-------很多转换时需要用到的字符文件
.xpdfrc:此文件是用来声明转换字符集对应路径的文件
.5) 修改xpdfrc文件(文件原名为sample-xpdfrc)
.修改文件内容为:
.#----- begin Chinese Simplified support package
.cidToUnicode Adobe-GB1 xpdf-chinese-simplified\Adobe-GB1.cidToUnicode
.unicodeMap ISO-2022-CN xpdf-chinese-simplified\ISO-2022-CN.unicodeMap
.unicodeMap EUC-CN xpdf-chinese-simplified\EUC-CN.unicodeMap
.unicodeMap GBK xpdf-chinese-simplified\GBK.unicodeMap
.cMapDir Adobe-GB1 xpdf-chinese-simplified\CMap
.toUnicodeDir xpdf-chinese-simplified\CMap
.fontDir C:\WINDOWS\Fonts
.displayCIDFontTT Adobe-GB1 C:\WINDOWS\Fonts\simhei.ttf
.#----- end Chinese Simplified support package
.
.#----- begin Chinese Simplified support package
.cidToUnicode Adobe-GB1 xpdf-chinese-simplified\Adobe-GB1.cidToUnicode
.unicodeMap ISO-2022-CN xpdf-chinese-simplified\ISO-2022-CN.unicodeMap
.unicodeMap EUC-CN xpdf-chinese-simplified\EUC-CN.unicodeMap
.unicodeMap GBK xpdf-chinese-simplified\GBK.unicodeMap
.cMapDir Adobe-GB1 xpdf-chinese-simplified\CMap
.toUnicodeDir xpdf-chinese-simplified\CMap
.fontDir C:\WINDOWS\Fonts
.displayCIDFontTT Adobe-GB1 C:\WINDOWS\Fonts\simhei.ttf
.#----- end Chinese Simplified support package
.
.6) 创建bat文件pdftohtml.bat(放置的路径不能包含空格)
.内容为:
.@echo off
.set folderPath=%1
.set filePath=%2
.cd /d %folderPath%
.pdftohtml -enc GBK %filePath%
.exit
.@echo off
.set folderPath=%1
.set filePath=%2
.cd /d %folderPath%
.pdftohtml -enc GBK %filePath%
.exit
.
.7) 创建类
.
.public class ConvertPdf
.{
.private static String INPUT_PATH;
.private static String PROJECT_PATH;
.
.public static void convertToHtml(String file, String project)
. {
. INPUT_PATH = file;
. PROJECT_PATH = project;
.if(checkContentType()==0)
. {
. toHtml();
. }
. }
.
.private static int checkContentType()
. {
. String type = INPUT_PATH.substring(INPUT_PATH.lastIndexOf(".") + 1, INPUT_PATH.length())
. .toLowerCase();
.if (type.equals("pdf"))
.return 0;
.else
.return 9;
. }
.
.private static void toHtml()
. {
.if(new File(INPUT_PATH).isFile())
. {
.try
. {
. String cmd = "cmd /c start X:\\pdftohtml.bat \"" + PROJECT_PATH + "\" \"" + INPUT_PATH + "\"";
. Runtime.getRuntime().exec(cmd);
. }
.catch (IOException e)
. {
. e.printStackTrace();
. }
. }
. }
.
.}
.
