Java 用Freemarker完美导出word文档（带图片）

第一步：制作word模板

 第二步：格式转换,将word另存为xml

 第三步:找到图片base64，删除base64替换成占位符${image},只修改图片的,其余的不用动

 第四步:加入依赖

 
            org.freemarker
            freemarker
            2.3.20
        

第五步:代码实现:

package com.wxz;


import freemarker.template.Configuration;
import freemarker.template.Template;
import sun.misc.BASE64Encoder;

import java.io.*;
import java.util.HashMap;
import java.util.Map;

public class TestWord {
	public static void genWord(){
		try {
			Map dataMap = new HashMap();
			dataMap.put("name", "二哈");
			dataMap.put("sex", "女");
			dataMap.put("birth", "1995-12-12");
			dataMap.put("age", "27");
			dataMap.put("address", "湖北省襄阳市保康县");
			dataMap.put("image", getImgFileToBase64("D:\\image\\dog.png"));
			Configuration configuration = new Configuration();
			configuration.setDefaultEncoding("utf-8");
			//.xml 模板文件所在目录
			configuration.setDirectoryForTemplateLoading(new File("D:\\模板"));
			// 输出文档路径及名称
			File outFile = new File("D:\\test.doc");
			//以utf-8的编码读取模板文件
			Template t =  configuration.getTemplate("test.xml","utf-8");
			Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"),10240);
			t.process(dataMap, out);
			out.close();
			System.out.println("生成成功");
		}catch (Exception e){
			e.printStackTrace();
			System.out.println("生成失败");
		}
	}

	public static String getImgFileToBase64(String imgFile) {
		//将图片文件转化为字节数组字符串，并对其进行Base64编码处理
		InputStream inputStream = null;
		byte[] buffer = null;
		//读取图片字节数组
		try {
			inputStream = new FileInputStream(imgFile);
			int count = 0;
			while (count == 0) {
				count = inputStream.available();
			}
			buffer = new byte[count];
			inputStream.read(buffer);
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if (inputStream != null) {
				try {
					// 关闭inputStream流
					inputStream.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
		// 对字节数组Base64编码
		return new BASE64Encoder().encode(buffer);
	}

	public static void main(String[] args) {
		genWord();
	}

}

第六步:测试
