這篇文章主要介紹了java 使用POI合并兩個(gè)word文檔的操作，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

java POI合并兩個(gè)word文檔

有需要的可以將主函數(shù)中寫死的地方改為一個(gè)List

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
 
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlOptions;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTBody; 
public class MergeDoc {
    public static void main (String[] args) throws Exception {
        InputStream in1 = null;
        InputStream in2 = null;
        OPCPackage src1Package = null;
        OPCPackage src2Package = null;
 
        OutputStream dest = new FileOutputStream("dest.docx");
        try {
            in1 = new FileInputStream("/Users/liuyahui/test.docx");
            in2 = new FileInputStream("/Users/liuyahui/test1.docx");
            src1Package = OPCPackage.open(in1);
            src2Package = OPCPackage.open(in2);
        } catch (Exception e) {
            e.printStackTrace();
        }
 
        XWPFDocument src1Document = new XWPFDocument(src1Package);
        CTBody src1Body = src1Document.getDocument().getBody();
        XWPFParagraph p = src1Document.createParagraph();
        //設(shè)置分頁符
        p.setPageBreak(true);
        XWPFDocument src2Document = new XWPFDocument(src2Package);
        CTBody src2Body = src2Document.getDocument().getBody();
        appendBody(src1Body, src2Body);
        src1Document.write(dest); 
    }
 
    private static void appendBody(CTBody src, CTBody append) throws Exception {
        XmlOptions optionsOuter = new XmlOptions();
        optionsOuter.setSaveOuter();
        String appendString = append.xmlText(optionsOuter);
        String srcString = src.xmlText();
        String prefix = srcString.substring(0,srcString.indexOf(">")+1);
        String mainPart = srcString.substring(srcString.indexOf(">")+1,srcString.lastIndexOf("<"));
        String sufix = srcString.substring( srcString.lastIndexOf("<") );
        String addPart = appendString.substring(appendString.indexOf(">") + 1, appendString.lastIndexOf("<"));
        CTBody makeBody = CTBody.Factory.parse(prefix+mainPart+addPart+sufix);
        src.set(makeBody);
    } 
}

poi生成word --XWPFDocument 合并

 //兩個(gè)對(duì)象進(jìn)行追加
    public  XWPFDocument mergeWord(XWPFDocument document,XWPFDocument doucDocument2) throws Exception {
      XWPFDocument src1Document =document ;
      XWPFParagraph p = src1Document.createParagraph();
      //設(shè)置分頁符
      p.setPageBreak(true);
      CTBody src1Body = src1Document.getDocument().getBody();
      XWPFDocument src2Document = doucDocument2;
      CTBody src2Body = src2Document.getDocument().getBody();
//      XWPFParagraph p2 = src2Document.createParagraph(); 
      XmlOptions optionsOuter = new XmlOptions();
      optionsOuter.setSaveOuter();
      String appendString = src2Body.xmlText(optionsOuter);
      String srcString = src1Body.xmlText();
      String prefix = srcString.substring(0,srcString.indexOf(">")+1);
      String mainPart = srcString.substring(srcString.indexOf(">")+1,srcString.lastIndexOf("<"));
      String sufix = srcString.substring( srcString.lastIndexOf("<") );
      String addPart = appendString.substring(appendString.indexOf(">") + 1, appendString.lastIndexOf("<"));
      CTBody makeBody = CTBody.Factory.parse(prefix+mainPart+addPart+sufix);
      src1Body.set(makeBody);
      return src1Document;
  }

無限合并

  XWPFDocument xmd=list.get(0); //默認(rèn)獲取第一個(gè)作為模板
        for (int i=0;i<list.size()-1;i++) {
         xmd=mergeWord(xmd,list.get(i+1)); //相繼合并
  }

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
