如何向word文档写入数据
大致流程:
1.创建模板docx并取出document.xml
新建一个docx文档,放在D盘命名test_template.docx
2.用winrar打开test_template.docx,取出word/document.xml
把xml文件格式化一下看起来更清晰,并且把要替换的内容用freemarker的指令代替,最后将文件重命名为test.xml放在D盘下面
3.准备工作完毕,上代码了,这个类是把内容填充到xml
[java] view plain copy
- import java.io.File;
- import java.io.IOException;
- import java.io.Writer;
- import java.util.Map;
- import freemarker.template.Configuration;
- import freemarker.template.Template;
- import freemarker.template.TemplateException;
- public class XmlToExcel {
- private static XmlToExcel tplm = null;
- private Configuration cfg = null;
- private XmlToExcel() {
- cfg = new Configuration();
- try {
- // 注册tmlplate的load路径
- // cfg.setClassForTemplateLoading(this.getClass(), "/template/");
- cfg.setDirectoryForTemplateLoading(new File("D:/"));
- } catch (Exception e) {
- }
- }
- private static Template getTemplate(String name) throws IOException {
- if (tplm == null) {
- tplm = new XmlToExcel();
- }
- return tplm.cfg.getTemplate(name);
- }
- /**
- *
- * @param templatefile 模板文件
- * @param param 需要填充的内容
- * @param out 填充完成输出的文件
- * @throws IOException
- * @throws TemplateException
- */
- public static void process(String templatefile, Map param, Writer out) throws IOException, TemplateException {
- // 获取模板
- Template template = XmlToExcel.getTemplate(templatefile);
- template.setOutputEncoding("UTF-8");
- // 合并数据
- template.process(param, out);
- if (out != null) {
- out.close();
- }
- }
- }
4.这个类是把填充完毕的xml转成docx
[java] view plain copy
- import java.io.File;
- import java.io.FileInputStream;
- import java.io.FileOutputStream;
- import java.io.IOException;
- import java.io.InputStream;
- import java.util.Enumeration;
- import java.util.zip.ZipEntry;
- import java.util.zip.ZipException;
- import java.util.zip.ZipFile;
- import java.util.zip.ZipOutputStream;
- /**
- * 其实docx属于zip的一种,这里只需要操作word/document.xml中的数据,其他的数据不用动
- *
- * @author yigehui
- *
- */
- public class XmlToDocx {
- /**
- *
- * @param documentFile 动态生成数据的docunment.xml文件
- * @param docxTemplate docx的模板
- * @param toFileName 需要导出的文件路径
- * @throws ZipException
- * @throws IOException
- */
- public void outDocx(File documentFile, String docxTemplate, String toFilePath) throws ZipException, IOException {
- try {
- File docxFile = new File(docxTemplate);
- ZipFile zipFile = new ZipFile(docxFile);
- Enumeration<? extends ZipEntry> zipEntrys = zipFile.entries();
- ZipOutputStream zipout = new ZipOutputStream(new FileOutputStream(toFilePath));
- int len = -1;
- byte[] buffer = new byte[1024];
- while (zipEntrys.hasMoreElements()) {
- ZipEntry next = zipEntrys.nextElement();
- InputStream is = zipFile.getInputStream(next);
- // 把输入流的文件传到输出流中 如果是word/document.xml由我们输入
- zipout.putNextEntry(new ZipEntry(next.toString()));
- if ("word/document.xml".equals(next.toString())) {
- InputStream in = new FileInputStream(documentFile);
- while ((len = in.read(buffer)) != -1) {
- zipout.write(buffer, 0, len);
- }
- in.close();
- } else {
- while ((len = is.read(buffer)) != -1) {
- zipout.write(buffer, 0, len);
- }
- is.close();
- }
- }
- zipout.close();
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- }
5.main方法调用
[java] view plain copy
- public static void main(String[] args) throws IOException, TemplateException {
- try {
- // xml的文件名
- String xmlTemplate = "test.xml";
- // docx的路径和文件名
- String docxTemplate = "d:\\test_template.docx";
- // 填充完数据的临时xml
- String xmlTemp = "d:\\temp.xml";
- // 目标文件名
- String toFilePath = "d:\\test.docx";
- Writer w = new FileWriter(new File(xmlTemp));
- // 1.需要动态传入的数据
- Map<String, Object> p = new HashMap<String, Object>();
- List<String> students = new ArrayList<String>();
- students.add("张三");
- students.add("李四");
- students.add("王二");
- p.put("ddeptdept", "研发部门");
- p.put("ddatedate", "2016-12-15");
- p.put("dnamename", students);
- // 2.把map中的数据动态由freemarker传给xml
- XmlToExcel.process(xmlTemplate, p, w);
- // 3.把填充完成的xml写入到docx中
- XmlToDocx xtd = new XmlToDocx();
- xtd.outDocx(new File(xmlTemp), docxTemplate, toFilePath);
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
