POI Word 模板 文字 图片 替换_JAVA_编程开发_程序员俱乐部

实验环境：POI3.7+Word2007

Word模板：

替换后效果：

代码：

1、入口文件

class="java" name="code">public class Test {
	
	public static void main(String[] args) throws Exception {
		
		Map<String, Object> param = new HashMap<String, Object>();
		param.put("${name}", "huangqiqing");
		param.put("${zhuanye}", "信息管理与信息系统");
		param.put("${sex}", "男");
		param.put("${school_name}", "山东财经大学");
		param.put("${date}", new Date().toString());
		
		Map<String,Object> header = new HashMap<String, Object>();
		header.put("width", 100);
		header.put("height", 150);
		header.put("type", "jpg");
		header.put("content", WordUtil.inputStream2ByteArray(new FileInputStream("c:\\new.jpg"), true));
		param.put("${header}",header);
		
		Map<String,Object> twocode = new HashMap<String, Object>();
		twocode.put("width", 100);
		twocode.put("height", 100);
		twocode.put("type", "png");
		twocode.put("content", ZxingEncoderHandler.getTwoCodeByteArray("测试二维码,huangqiqing", 100,100));
		param.put("${twocode}",twocode);
		
		CustomXWPFDocument doc = WordUtil.generateWord(param, "c:\\1.docx");
		FileOutputStream fopts = new FileOutputStream("c:/2.docx");
		doc.write(fopts);
		fopts.close();
	}
}

2、封装的工具类WordUtil.java

3、重写的类 CustomXWPFDocument

package test1;
