java使用POI操作XWPFDocument 生成Word实战(一)
注:我使用的word 2016
功能简介:
(1)使用jsoup解析html得到我用来生成word的文本(这个你们可以忽略)
(2)生成word、设置页边距、设置页脚(页码),设置页码(文本)
一、解析html
Document doc = Jsoup.parseBodyFragment(contents); Element body = doc.body(); Elements es = body.getAllElements();
二、循环Elements获取我需要的html标签
boolean tag = false; for (Element e : es) { //跳过第一个(默认会把整个对象当做第一个) if(!tag) { tag = true; continue; } //创建段落:生成word(核心) createXWPFParagraph(docxDocument,e); }
三、生成段落
/** * 构建段落 * @param docxDocument * @param e */ public static void createXWPFParagraph(XWPFDocument docxDocument, Element e){ XWPFParagraph paragraph = docxDocument.createParagraph(); XWPFRun run = paragraph.createRun(); run.setText(e.text()); run.setTextPosition(35);//设置行间距 if(e.tagName().equals("titlename")){ paragraph.setAlignment(ParagraphAlignment.CENTER);//对齐方式 run.setBold(true);//加粗 run.setColor("000000");//设置颜色--十六进制 run.setFontFamily("宋体");//字体 run.setFontSize(24);//字体大小 }else if(e.tagName().equals("h1")){ addCustomHeadingStyle(docxDocument, "标题 1", 1); paragraph.setStyle("标题 1"); run.setBold(true); run.setColor("000000"); run.setFontFamily("宋体"); run.setFontSize(20); }else if(e.tagName().equals("h2")){ addCustomHeadingStyle(docxDocument, "标题 2", 2); paragraph.setStyle("标题 2"); run.setBold(true); run.setColor("000000"); run.setFontFamily("宋体"); run.setFontSize(18); }else if(e.tagName().equals("h3")){ addCustomHeadingStyle(docxDocument, "标题 3", 3); paragraph.setStyle("标题 3"); run.setBold(true); run.setColor("000000"); run.setFontFamily("宋体"); run.setFontSize(16); }else if(e.tagName().equals("p")){ //内容 paragraph.setAlignment(ParagraphAlignment.BOTH);//对齐方式 paragraph.setIndentationFirstLine(WordUtil.ONE_UNIT);//首行缩进:567==1厘米 run.setBold(false); run.setColor("001A35"); run.setFontFamily("宋体"); run.setFontSize(14); //run.addCarriageReturn();//回车键 }else if(e.tagName().equals("break")){ paragraph.setPageBreak(true);//段前分页(ctrl+enter) } }
四、设置页边距
/** * 设置页边距 (word中1厘米约等于567) * @param document * @param left * @param top * @param right * @param bottom */ public static void setDocumentMargin(XWPFDocument document, String left,String top, String right, String bottom) { CTSectPr sectPr = document.getDocument().getBody().addNewSectPr(); CTPageMar ctpagemar = sectPr.addNewPgMar(); if (StringUtils.isNotBlank(left)) { ctpagemar.setLeft(new BigInteger(left)); } if (StringUtils.isNotBlank(top)) { ctpagemar.setTop(new BigInteger(top)); } if (StringUtils.isNotBlank(right)) { ctpagemar.setRight(new BigInteger(right)); } if (StringUtils.isNotBlank(bottom)) { ctpagemar.setBottom(new BigInteger(bottom)); } }
五、创建页眉
/** * 创建默认页眉 * * @param docx XWPFDocument文档对象 * @param text 页眉文本 * @return 返回文档帮助类对象,可用于方法链调用 * @throws XmlException XML异常 * @throws IOException IO异常 * @throws InvalidFormatException 非法格式异常 * @throws FileNotFoundException 找不到文件异常 */ public static void createDefaultHeader(final XWPFDocument docx, final String text){ CTP ctp = CTP.Factory.newInstance(); XWPFParagraph paragraph = new XWPFParagraph(ctp, docx); ctp.addNewR().addNewT().setStringValue(text); ctp.addNewR().addNewT().setSpace(SpaceAttribute.Space.PRESERVE); CTSectPr sectPr = docx.getDocument().getBody().isSetSectPr() ? docx.getDocument().getBody().getSectPr() : docx.getDocument().getBody().addNewSectPr(); XWPFHeaderFooterPolicy policy = new XWPFHeaderFooterPolicy(docx, sectPr); XWPFHeader header = policy.createHeader(STHdrFtr.DEFAULT, new XWPFParagraph[] { paragraph }); header.setXWPFDocument(docx); }}
六、创建页脚
/** * 创建默认的页脚(该页脚主要只居中显示页码) * * @param docx * XWPFDocument文档对象 * @return 返回文档帮助类对象,可用于方法链调用 * @throws XmlException * XML异常 * @throws IOException * IO异常 */ public static void createDefaultFooter(final XWPFDocument docx) { // TODO 设置页码起始值 CTP pageNo = CTP.Factory.newInstance(); XWPFParagraph footer = new XWPFParagraph(pageNo, docx); CTPPr begin = pageNo.addNewPPr(); begin.addNewPStyle().setVal(STYLE_FOOTER); begin.addNewJc().setVal(STJc.CENTER); pageNo.addNewR().addNewFldChar().setFldCharType(STFldCharType.BEGIN); pageNo.addNewR().addNewInstrText().setStringValue("PAGE \\* MERGEFORMAT"); pageNo.addNewR().addNewFldChar().setFldCharType(STFldCharType.SEPARATE); CTR end = pageNo.addNewR(); CTRPr endRPr = end.addNewRPr(); endRPr.addNewNoProof(); endRPr.addNewLang().setVal(LANG_ZH_CN); end.addNewFldChar().setFldCharType(STFldCharType.END); CTSectPr sectPr = docx.getDocument().getBody().isSetSectPr() ? docx.getDocument().getBody().getSectPr() : docx.getDocument().getBody().addNewSectPr(); XWPFHeaderFooterPolicy policy = new XWPFHeaderFooterPolicy(docx, sectPr); policy.createFooter(STHdrFtr.DEFAULT, new XWPFParagraph[] { footer }); }
七、自定义标题样式(这个在我另一篇word基础中也有提及)
/** * 增加自定义标题样式。这里用的是stackoverflow的源码 * * @param docxDocument 目标文档 * @param strStyleId 样式名称 * @param headingLevel 样式级别 */ private static void addCustomHeadingStyle(XWPFDocument docxDocument, String strStyleId, int headingLevel) { CTStyle ctStyle = CTStyle.Factory.newInstance(); ctStyle.setStyleId(strStyleId); CTString styleName = CTString.Factory.newInstance(); styleName.setVal(strStyleId); ctStyle.setName(styleName); CTDecimalNumber indentNumber = CTDecimalNumber.Factory.newInstance(); indentNumber.setVal(BigInteger.valueOf(headingLevel)); // lower number > style is more prominent in the formats bar ctStyle.setUiPriority(indentNumber); CTOnOff onoffnull = CTOnOff.Factory.newInstance(); ctStyle.setUnhideWhenUsed(onoffnull); // style shows up in the formats bar ctStyle.setQFormat(onoffnull); // style defines a heading of the given level CTPPr ppr = CTPPr.Factory.newInstance(); ppr.setOutlineLvl(indentNumber); ctStyle.setPPr(ppr); XWPFStyle style = new XWPFStyle(ctStyle); // is a null op if already defined XWPFStyles styles = docxDocument.createStyles(); style.setType(STStyleType.PARAGRAPH); styles.addStyle(style); }
八、设置页码大小及纸张方向
/** * 设置页面大小及纸张方向 landscape横向 * @param document * @param width * @param height * @param stValue */ public void setDocumentSize(XWPFDocument document, String width,String height, STPageOrientation.Enum stValue) { CTSectPr sectPr = document.getDocument().getBody().addNewSectPr(); CTPageSz pgsz = sectPr.isSetPgSz() ? sectPr.getPgSz() : sectPr.addNewPgSz(); pgsz.setH(new BigInteger(height)); pgsz.setW(new BigInteger(width)); pgsz.setOrient(stValue); }
九、效果展示
十、demo源码及生成的word文件(相应的jar包大家可以去阿里的maven仓库下载)
