java生成docx_JAVA通过模板生成DOCX文档

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

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

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 p = new HashMap();

List students = new ArrayList();

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();

}

}
