替换docx文件里面的 ${} 字符串
public class main { public static void main(string[] args) throws exception { string template = "c:\\users\\lzh\\desktop\\模板.docx"; string outsrc = "c:\\users\\lzh\\desktop\\简历.docx"; var is = new fileinputstream(template); var os = new fileoutputstream(outsrc); editdocx(os, is, xml -> { map<string,string> map = new hashmap<>(); map.put("${name}", "李**"); map.put("${sex}", "男"); map.put("${age}", "21"); pattern p = pattern.compile("(\\$\\{)([\\w]+)(\\})"); matcher m = p.matcher(xml); stringbuffer sb = new stringbuffer(); while (m.find()) { string group = m.group(); m.appendreplacement(sb, map.get(group)); } m.appendtail(sb); xml = sb.tostring(); return xml; }); } public static void editdocx(outputstream bos,inputstream is, process process){ zipinputstream zin = new zipinputstream(is); zipoutputstream zos = new zipoutputstream(bos); try { zipentry entry; while((entry = zin.getnextentry()) != null) { //把输入流的文件传到输出流中 如果是word/document.xml由我们输入 zos.putnextentry(new zipentry(entry.getname())); if("word/document.xml".equals(entry.getname())){ string xml = new bufferedreader(new inputstreamreader(zin)).lines().collect(collectors.joining(system.lineseparator())); xml = process.process(xml); bytearrayinputstream bytein = new bytearrayinputstream(xml.getbytes()); int c; while ((c = bytein.read()) != -1) { zos.write(c); } bytein.close(); }else { int c; while ((c = zin.read()) != -1) { zos.write(c); } } } } catch (ioexception e) { e.printstacktrace(); } finally { try { zos.close(); zin.closeentry(); zin.close(); } catch (ioexception e) { e.printstacktrace(); } } } } interface process { string process(string xml); }
