用 Freemarker 生成 word 文档(包含图片)

时间:2024-04-05 13:08:16

1. 用word写一个需要导出的word模板,然后存为xml格式。

2. 将xml中需要动态修改内容的地方,换成freemarker的标识符,例如:

<w:p wsp:rsidR="00D02906" wsp:rsidRDefault="00FA4C58" wsp:rsidP="00FA4C58">
<w:pPr>
<w:jc w:val="center"/>
<w:rPr>
<w:rFonts w:hint="fareast"/>
</w:rPr>
</w:pPr>
<w:r>
<w:t>${year}</w:t>
</w:r>
<w:r>
<w:rPr>
<wx:font wx:val="宋体"/>
</w:rPr>
<w:t>年度工作报告</w:t>
</w:r>
</w:p>

3. 用代码生成:

import freemarker.template.Configuration;
import freemarker.template.Template; import java.io.*;
import java.util.HashMap;
import java.util.Map; /**
* @Class name: CreateDoc
* <p/>
* Short description on the purpose of the program.
* @author : youfeng
* @modified : 8/29/11
*/
public class CreateDoc { private Configuration configuration = null; public CreateDoc() {
configuration = new Configuration();
configuration.setDefaultEncoding("utf-8");
} public void create() throws Exception {
Map<String, Object> map = new HashMap<String, Object>();
map.put("date", "2011");
map.put("modifyDate", "2011/8/29");
map.put("modifyUser", "Zhu You Feng"); configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
Template t = configuration.getTemplate("doc1.ftl");
File outFile = new File("D:/outFile.doc");
Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
t.process(map, out);
} public static void main(String[] args) throws Exception {
new CreateDoc().create(); }
}

添加图片

如果你需要在word中添加图片,那你就在第一步制作模板时,加入一张图片占位,然后打开xml文档,可以看到如下的一片base64编码后的代码:

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">iVBORw0…(很省略很省略)…CC</w:binData>

只要将base64的代码替换成例如:${image},如下:

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">${image}</w:binData>

这里要注意“>${image}<”这尖括号中间不能加任何其他的诸如空格,tab,换行等符号。

然后用代码生成:

import freemarker.template.Configuration;
import freemarker.template.Template;
import sun.misc.BASE64Encoder; import java.io.*;
import java.util.HashMap;
import java.util.Map; /**
* @Class name: CreateDoc
* @author: youfeng
* @modified: 8/29/11
*/
public class CreateDocWithImage { private Configuration configuration = null; public CreateDocWithImage() {
configuration = new Configuration();
configuration.setDefaultEncoding("utf-8");
} public void create() throws Exception {
Map<String, Object> map = new HashMap<String, Object>();
map.put("year", "2011");
map.put("person", "Zhu You Feng");
map.put("image", getImageStr()); configuration.setClassForTemplateLoading(this.getClass(), "/docTemplate/");
Template t = configuration.getTemplate("doc2.ftl");
File outFile = new File("D:/outFile.doc");
Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
t.process(map, out);
} private String getImageStr() {
String imgFile = "d:/test.jpg";
InputStream in = null;
byte[] data = null;
try {
in = new FileInputStream(imgFile);
data = new byte[in.available()];
in.read(data);
in.close();
} catch (IOException e) {
e.printStackTrace();
}
BASE64Encoder encoder = new BASE64Encoder();
return encoder.encode(data);
} public static void main(String[] args) throws Exception {
new CreateDocWithImage().create(); }
}

自定义载入模板

import freemarker.cache.TemplateLoader;

map.put("date", "2012");
map.put("modifyDate", "2011/8/29");
map.put("modifyUser", "Zhu You Feng");
new DocumentGenerator().createDoc("", "D:/outFile2.doc", map);
} public DocumentGenerator() {
configuration = new Configuration();
configuration.setDefaultEncoding("utf-8");
configuration.setClassicCompatible(true);
configuration.setTemplateLoader(new ByteArrayStreamTemplateLoader(new ByteArrayInputStream(
getBytesFromFile(new File("D:/ownProject/freemarkerToDoc/src/main/resources/docTemplate/doc1.ftl"))
)));
} /**
* @param fileName
* @param outFileName
* @param dataMap
*/
public void createDoc(String fileName, String outFileName, Map dataMap) {
Template t = null;
try {
t = configuration.getTemplate(fileName);
} catch (IOException e) {
e.printStackTrace();
}
File outFile = new File(outFileName);
Writer out = null;
try {
out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));
} catch (FileNotFoundException e1) {
e1.printStackTrace();
}
try {
t.process(dataMap, out);
} catch (TemplateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} public byte[] getBytesFromFile(File f) {
if (f == null) {
return null;
}
try {
FileInputStream stream = new FileInputStream(f);
ByteArrayOutputStream out = new ByteArrayOutputStream(1000);
byte[] b = new byte[1000];
int n;
while ((n = stream.read(b)) != -1)
out.write(b, 0, n);
stream.close();
out.close();
return out.toByteArray();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
} class ByteArrayStreamTemplateLoader implements TemplateLoader { InputStream in = null; public ByteArrayStreamTemplateLoader(ByteArrayInputStream inputStream) {
in = inputStream;
} public Object findTemplateSource(String name) throws IOException {
System.out.println("findTemplateSource");
return in;
} public long getLastModified(Object templateSource) {
return 0;
} public Reader getReader(Object templateSource, String encoding) throws IOException {
System.out.println("getReader");
return new InputStreamReader(in);
} public void closeTemplateSource(Object templateSource) throws IOException {
System.out.println("closeTemplateSource");
if (in != null) {
in.close();
}
}
