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;
/**
* 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 static void main(String[] args) {
excelToHtml(
"D:\\work\\apache-tomcat-6.0.36\\webapps\\ReportSystem\\upload\\1374758916167.xls",
"D:\\work\\apache-tomcat-6.0.36\\webapps\\ReportSystem\\upload\\1374758916167.html");
}
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");
}
}
