java 使用POI合并两个word文档

java poi合并两个word文档

有需要的可以将主函数中写死的地方改为一个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();
        //设置分页符
        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

 //两个对象进行追加
    public  xwpfdocument mergeword(xwpfdocument document,xwpfdocument doucdocument2) throws exception {
      xwpfdocument src1document =document ;
      xwpfparagraph p = src1document.createparagraph();
      //设置分页符
      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;
  }

无限合并

  xwpfdocument xmd=list.get(0); //默认获取第一个作为模板
        for (int i=0;i<list.size()-1;i++) {
         xmd=mergeword(xmd,list.get(i+1)); //相继合并
  }

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
