Java-jacob-文件转HTML

Java-jacob-文件转HTML：

下载jacob的jar包，然后举个例子。

	public static final int WORD_HTML = 8;

	public static final int WORD_TXT = 7;

	public static final int EXCEL_HTML = 44;

	/**

	 *
	 * @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[] {});
		}
	}

	 */
	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();

Jacob把Word Excel PPT转成Html

首先，必须将jacob-1.15-M3-x86.dll这个文件（视版本而定，在32位xp系统中使用该文件，在64位系统中，如win7，就得使用该文件jacob-1.15-M3-x64.dll了）拷贝到C:\Program Files\Java\jdk1.6.0_04\jre\bin的目录下，然后将jacob.jar在添加到C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib的目录下，在项目中导入jacob.jar即可使用下面程序：

1.word转html

Word转起来还是比较容易的，不会出什么问题，转换之后进程自动关闭。

public class Word2Html {

public static void change(String filename, String htmlFilename) {

ActiveXComponent xl = new ActiveXComponent("Word.Application");

//打开一个word，不显示窗口

try {

Dispatch.put(xl, "Visible", new Variant(false));

Object workbooks = xl.getProperty("Documents").toDispatch();

Object workbook = Dispatch.call((Dispatch) workbooks, "Open",

filename).toDispatch();

Dispatch.invoke((Dispatch) workbook, "SaveAs", Dispatch.Method,

new Object[] { htmlFilename, new Variant(8) }, new int[1]);

Variant f = new Variant(false);

//Close关闭文件，不关闭窗口

Dispatch.call((Dispatch) workbooks, "Close", f);

} catch (Exception e) {

e.printStackTrace();

} finally {

// 调用office关闭方法，关闭窗口和word进程

xl.invoke("Quit", new Variant[] {});

xl = null;

}

}

public static void main(String[] args) {

Word2Html.change("d:/a.doc", "d:/a");

}

}

因为word转html之后，word进程自动关闭，所以在finally中不写关闭进程代码，但在excel和ppt转换后进程不会自动关闭，要加上关闭进程代码。

2.Excel转html

Excel最头疼的就是转换完之后，进程不会释放，而且每一次转换都会加一个进程，崩溃！！

无奈之下不得不在finally中杀掉excel进程。

public class Excel2Html {

public static void change(String filename, String htmlFilename) {

ActiveXComponent xl = new ActiveXComponent("Excel.Application");

try {

Dispatch.put(xl, "Visible", new Variant(false));

//打开一个Excel，不显示窗口

Object workbooks = xl.getProperty("workbooks").toDispatch();

Object workbook = Dispatch.call((Dispatch) workbooks, "Open",

filename).toDispatch();

Dispatch.invoke((Dispatch) workbook, "SaveAs", Dispatch.Method,

new Object[] { htmlFilename, new Variant(44) }, new int[1]);

Dispatch.call((Dispatch) workbooks, "Close");

} catch (Exception e) {

e.printStackTrace();

} finally {

xl.invoke("Quit", new Variant[] {});

xl = null;

Process process;

int pid = 0;

try {

process = Runtime.getRuntime().exec("tasklist");

Scanner in = new Scanner(process.getInputStream());

while (in.hasNextLine()) {

String p = in.nextLine();

// 打印所有进程

System.out.println(p);

if (p.contains("EXCEL.EXE")) {

StringBuffer buf = new StringBuffer();

for (int i = 0; i < p.length(); i++) {

char ch = p.charAt(i);

if (ch != ' ') {

buf.append(ch);

}

}

// 打印pid，根据pid关闭进程

System.out.println(buf.toString().split("Console")[0]

.substring("EXCEL.EXE".length()));

pid = Integer.parseInt(buf.toString().split("Console")[0]

.substring("EXCEL.EXE".length()));

Runtime.getRuntime().exec("tskill"+" "+pid);

}

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

public static void main(String[] args) {

Excel2Html.change("d:/b.xls", "d:/b");

}

}

3.PPT转html

PPT转html最头疼的就是new Variant(false)会报错，无奈只能设成true，然后在finally中杀掉powerpnt进程。

public class Ppt2Html {

public static void change(String filename, String htmlFilename) {

ActiveXComponent xl = new ActiveXComponent("Powerpoint.Application");

try {

Dispatch.put(xl, "Visible", new Variant(true));

//打开一个PPT，显示窗口，PPT的不显示就会报错，狂晕！

Object workbooks = xl.getProperty("Presentations").toDispatch();

Object workbook = Dispatch.call((Dispatch) workbooks, "Open",

filename).toDispatch();

Dispatch.invoke((Dispatch) workbook, "SaveAs", Dispatch.Method,

new Object[] { htmlFilename, new Variant(20) }, new int[1]);

//Variant f = new Variant(false);

//Dispatch.call((Dispatch) workbooks, "Close",f);

//PPT的加这两行会报错，干脆注释上，反正在下面也关闭进程

} catch (Exception e) {

e.printStackTrace();

} finally {

xl.invoke("Quit", new Variant[] {});

xl = null;

Process process;

int pid = 0;

try {

process = Runtime.getRuntime().exec("tasklist");

Scanner in = new Scanner(process.getInputStream());

while (in.hasNextLine()) {

String p = in.nextLine();

// 打印所有进程

System.out.println(p);

if (p.contains("POWERPNT.EXE")) {

StringBuffer buf = new StringBuffer();

for (int i = 0; i < p.length(); i++) {

char ch = p.charAt(i);

if (ch != ' ') {

buf.append(ch);

}

}

// 打印pid，根据pid关闭进程

System.out.println(buf.toString().split("Console")[0]

.substring("POWERPNT.EXE".length()));

pid = Integer

.parseInt(buf.toString().split("Console")[0]

.substring("POWERPNT.EXE".length()));

Runtime.getRuntime().exec("tskill" + " " + pid);

}

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

public static void main(String[] args) {

Ppt2Html.change("d:/c.ppt", "d:/c");

}

}
