Freemarker导出带图片的word

1.新建一doc文档

 

2.另存为XML文档用编辑器打开可以看到标签<pkg:binaryData>中间有很多BASE64编码后图片的数据，删掉直接用 ${img} 替换(中间不能有空格)。

 

 

 

3.将后缀改为ftl

4.Java代码实现将图片的值处理成base64；

package servlet;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map;

import org.junit.Test;

import com.sun.org.apache.bcel.internal.generic.NEW;

import freemarker.core.ParseException;
import freemarker.template.Configuration;
import freemarker.template.MalformedTemplateNameException;
import freemarker.template.Template;
import freemarker.template.TemplateException;
import freemarker.template.TemplateNotFoundException;
import sun.misc.BASE64Encoder;

public class FreemarkerExportWordPicture {

    @Test
    public  void test1() throws Exception {
        Map<String,Object> dataMap = new HashMap<String,Object>();  
        Configuration configuration = new Configuration();
        configuration.setClassForTemplateLoading(this.getClass(),""); 
        File outFile = new File("F:/test4.doc");  
        dataMap.put("img", getImageStr());
         //以utf-8的编码读取ftl文件  
         Template t =  configuration.getTemplate("test4.ftl","utf-8");  
         Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"),10240);  
         t.process(dataMap, out);  
         out.close();
    }
    
    
    //下面这段代码对图片进行base64编码
    private String getImageStr() throws Exception {
        String imgFile = "C:/Users/liqiang/Desktop/kdmt.jpg";
        InputStream inputStream = null;
        byte []data=null;
        inputStream = new FileInputStream(imgFile);
        data = new byte[inputStream.available()];
        inputStream.read(data);
        inputStream .close();
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(data);
        
    }
}

 

4.测试
