docx4j操作word.docx

1、docx4j操作wordDocx4j操作word1.Docx4j介绍1.1.Docx4j介绍docx4j是一个用于创建和操作Microsoft Open XML (Word docx, Powerpoint pptx, 和 Excel xlsx)文件的Java类库。http:/www.docx4java.org/trac/docx4j 官方主页。2.Docx4j操作2.1.初始读取word WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage .load(WordChartDataRenderTest.class.get

2、ClassLoader().getResourceAsStream(tpl.docx);2.2.标签替换在操作word的时候，多数情况的下是通过标签进行替换相关的内容。标签在word中可以定义一个位置，或者标示一个段落内容。在一个模板中定义好标签，在插入-书签：然后定义好名称。在java的代码中对标签进行遍历，得到该名称，并替换成相关的内容。/ try List paragraphs = wordMLPackage.getMainDocumentPart().getContent(); RangeFinder rt = new RangeFinder(CTBookmark, CTMarkupR

3、ange); new TraversalUtil(paragraphs, rt); / 遍历所有的标签 for (CTBookmark bm : rt.getStarts() if (StringUtil.isEmpty(bm.getName() continue; ReportData obj = data.get(bm.getName(); if (obj = null | !(obj instanceof ReportData) if(bm.getName().indexOf(_) = 0) else logger.error(bookmark fill data, data is em

4、pty! + bm.getName(); continue; try List theList = null; ParaRPr rpr = null; if (bm.getParent() instanceof P) PPr pprTemp = (P) (bm.getParent().getPPr(); if (pprTemp = null) rpr = null; else rpr = (P) (bm.getParent().getPPr().getRPr(); theList = (ContentAccessor) (bm.getParent().getContent(); else co

5、ntinue; int rangeStart = -1; int rangeEnd = -1; int i = 0; for (Object ox : theList) Object listEntry = XmlUtils.unwrap(ox); if (listEntry.equals(bm) rangeStart = i + 1; else if (listEntry instanceof CTMarkupRange) if (CTMarkupRange) listEntry).getId().equals(bm.getId() rangeEnd = i - 1; break; i+;

6、if (rangeStart = 0) for (int j = rangeEnd; j = rangeStart; j-) theList.remove(j); org.docx4j.wml.R run = factory.createR(); org.docx4j.wml.Text t = factory.createText(); run.getContent().add(t); if (rpr != null) run.setRPr(paraRPr2RPr(rpr, factory); t.setValue(value); theList.add(rangeStart, run); c

7、atch (Exception cce) logger.error(cce.getMessage(), cce); throw cce; catch (Exception e) throw e; 找到相应的位置然后替换，相应的文本，需要注意的是替换相关的内容的格式。2.3.chart图表内容替换chart图的替换有两种方法，一种是word里面的插入的图表，这时在进行更改值的时候，需要更改图标的内容，然后再更新excel的相关内容。【没有找到更新一个自动更新另一个的方法。】public class BarChartTest public static void main(String args)

8、 throws Docx4JException WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage .load(WordChartDataRenderTest.class.getClassLoader().getResourceAsStream(tpl.docx); ChartData data = new ChartData(); ObjectFactory factory = new org.docx4j.wml.ObjectFactory(); List paragraphs = wordMLPackage.ge
