利用jacob转PDF，poi生成Word(注：仅支持windows平台，需要jacob-1.14.3-x64.dll文件，存放在C:\Windows\System32路径下)
一、步骤：
1.导入所需Jar包 2.生成Word文档 3.转为PDF文件
二、所需Jar包，如图：
三、生成Word文件代码：
// 返回Docx中需要替换的特殊字符，没有重复项
// 推荐传入正则表达式参数"\\$\\{[^{}]+\\}"
public ArrayList<String> getReplaceElementsInWord(String filePath, String regex) {
String[] p = filePath.split("\\.");
if (p.length > 0) {// 判断文件有无扩展名
// 比较文件扩展名
if (p[p.length - 1].equalsIgnoreCase("doc")) {
ArrayList<String> al = new ArrayList<>();
File file = new File(filePath);
HWPFDocument document = null;
try {
InputStream is = new FileInputStream(file);
document = new HWPFDocument(is);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Range range = document.getRange();
String rangeText = range.text();
CharSequence cs = rangeText.subSequence(0, rangeText.length());
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(cs);
int startPosition = 0;
while (matcher.find(startPosition)) {
if (!al.contains(matcher.group())) {
al.add(matcher.group());
}
startPosition = matcher.end();
}
return al;
} else if (p[p.length - 1].equalsIgnoreCase("docx")) {
ArrayList<String> al = new ArrayList<>();
XWPFDocument document = null;
try {
document = new XWPFDocument(POIXMLDocument.openPackage(filePath));
} catch (IOException e) {
e.printStackTrace();
}
// 遍历段落
Iterator<XWPFParagraph> itPara = document.getParagraphsIterator();
while (itPara.hasNext()) {
XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
String paragraphString = paragraph.getText();
CharSequence cs = paragraphString.subSequence(0, paragraphString.length());
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(cs);
int startPosition = 0;
while (matcher.find(startPosition)) {
if (!al.contains(matcher.group())) {
al.add(matcher.group());
}
startPosition = matcher.end();
}
}
// 遍历表
Iterator<XWPFTable> itTable = document.getTablesIterator();
while (itTable.hasNext()) {
XWPFTable table = (XWPFTable) itTable.next();
int rcount = table.getNumberOfRows();
for (int i = 0; i < rcount; i++) {
XWPFTableRow row = table.getRow(i);
List<XWPFTableCell> cells = row.getTableCells();
for (XWPFTableCell cell : cells) {
String cellText = "";
cellText = cell.getText();
CharSequence cs = cellText.subSequence(0, cellText.length());
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(cs);
int startPosition = 0;
while (matcher.find(startPosition)) {
if (!al.contains(matcher.group())) {
al.add(matcher.group());
}
startPosition = matcher.end();
}
}
}
}
return al;
} else {
return null;
}
} else {
return null;
}
}
// 替换word中需要替换的特殊字符
public static boolean replaceAndGenerateWord(String srcPath, String destPath, Map<String, String> map) {
String[] sp = srcPath.split("\\.");
String[] dp = destPath.split("\\.");
if ((sp.length > 0) && (dp.length > 0)) {// 判断文件有无扩展名
// 比较文件扩展名
if (sp[sp.length - 1].equalsIgnoreCase("docx")) {
try {
XWPFDocument document = new XWPFDocument(POIXMLDocument.openPackage(srcPath));
// 替换段落中的指定文字
Iterator<XWPFParagraph> itPara = document.getParagraphsIterator();
while (itPara.hasNext()) {
XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
List<XWPFRun> runs = paragraph.getRuns();
for (int i = 0; i < runs.size(); i++) {
String onegaString = runs.get(i).getText(runs.get(i).getTextPosition());
for (Map.Entry<String, String> entry : map.entrySet()) {
onegaString = onegaString.replace(entry.getKey(), entry.getValue());
}
runs.get(i).setText(onegaString, 0);
}
}
// 替换表格中的指定文字
Iterator<XWPFTable> itTable = document.getTablesIterator();
while (itTable.hasNext()) {
XWPFTable table = (XWPFTable) itTable.next();
int remount = table.getNumberOfRows();
for (int i = 0; i < remount; i++) {
XWPFTableRow row = table.getRow(i);
List<XWPFTableCell> cells = row.getTableCells();
for (XWPFTableCell cell : cells) {
String cellTextString = cell.getText();
for (Map.Entry<String, String> e : map.entrySet()) {
if (cellTextString.contains(e.getKey()))
cellTextString = cellTextString.replace(e.getKey(), e.getValue());
}
cell.removeParagraph(0);
cell.setText(cellTextString);
}
}
}
FileOutputStream outStream = null;
outStream = new FileOutputStream(destPath);
document.write(outStream);
outStream.close();
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
// doc只能生成doc，如果生成docx会出错
} else if ((sp[sp.length - 1].equalsIgnoreCase("doc")) && (dp[dp.length - 1].equalsIgnoreCase("doc"))) {
HWPFDocument document = null;
try {
document = new HWPFDocument(new FileInputStream(srcPath));
Range range = document.getRange();
for (Map.Entry<String, String> entry : map.entrySet()) {
range.replaceText(entry.getKey(), entry.getValue());
}
FileOutputStream outStream = new FileOutputStream(destPath);
document.write(outStream);
outStream.close();
return true;
} catch (FileNotFoundException e) {
e.printStackTrace();
return false;
} catch (IOException e) {
e.printStackTrace();
return false;
}
} else {
return false;
}
} else {
return false;
}
}
四、Word转PDF代码：
public static void wordToPdf(String fromAddress, String toAddress) {
ActiveXComponent ax = null;
try {
long startTime = System.currentTimeMillis();
ax = new ActiveXComponent("Word.Application");
//设置打开word文档不可见
ax.setProperty("Visible", false);
//获取Word文档中所有内容
Dispatch docs = ax.getProperty("Documents").toDispatch();
//打开word文档，并设置word为不可编辑和不需确认
Dispatch doc = Dispatch.call(docs,
"Open",
fromAddress,// FileName
false,// ConfirmConversions
true // ReadOnly
).toDispatch();
File tofile = new File(toAddress);
if (tofile.exists()) {
tofile.delete();
}
//word文件另存为pdf文件
Dispatch.call(doc,//
"SaveAs", //
toAddress, // FileName
wdFormatPDF);
//关闭word文档
Dispatch.call(doc, "Close", false);
long endTime = System.currentTimeMillis();
System.out.println("转化完成,总共耗时" + (endTime - startTime) + "ms。");
} catch (Exception e) {
System.out.println("========Error:文档转换失败：" + e.getMessage());
} finally {
if (ax != null)
ax.invoke("Quit", new Variant[]{});
}
}
