推荐答案

此方法将替换整个文档中的表格、标题和段落中的所有选定文本.

This methods will replace all selected text, in tables, headers and paragraph, in the entire document.

public XWPFDocument replacePOI(XWPFDocument doc, String placeHolder, String replaceText){
    // REPLACE ALL HEADERS
    for (XWPFHeader header : doc.getHeaderList()) 
        replaceAllBodyElements(header.getBodyElements(), placeHolder, replaceText);
    // REPLACE BODY
    replaceAllBodyElements(doc.getBodyElements(), placeHolder, replaceText);
    return doc;
}

private void replaceAllBodyElements(List<IBodyElement> bodyElements, String placeHolder, String replaceText){
    for (IBodyElement bodyElement : bodyElements) {
        if (bodyElement.getElementType().compareTo(BodyElementType.PARAGRAPH) == 0)
            replaceParagraph((XWPFParagraph) bodyElement, placeHolder, replaceText);
        if (bodyElement.getElementType().compareTo(BodyElementType.TABLE) == 0)
            replaceTable((XWPFTable) bodyElement, placeHolder, replaceText);
    }
}

private void replaceTable(XWPFTable table, String placeHolder, String replaceText) {
    for (XWPFTableRow row : table.getRows()) {
        for (XWPFTableCell cell : row.getTableCells()) {
            for (IBodyElement bodyElement : cell.getBodyElements()) {
                if (bodyElement.getElementType().compareTo(BodyElementType.PARAGRAPH) == 0) {
                    replaceParagraph((XWPFParagraph) bodyElement, placeHolder, replaceText);
                }
                if (bodyElement.getElementType().compareTo(BodyElementType.TABLE) == 0) {
                    replaceTable((XWPFTable) bodyElement, placeHolder, replaceText);
                }
            }
        }
    }  
}

private void replaceParagraph(XWPFParagraph paragraph, String placeHolder, String replaceText) {
    for (XWPFRun r : paragraph.getRuns()) {
        String text = r.getText(r.getTextPosition());
        if (text != null && text.contains(placeHolder)) {
            text = text.replace(placeHolder, replaceText);
            r.setText(text, 0);
        }
    }
}
