POI Word 模板 文字 图片 替换

实验环境：POI3.7+Word2007

Word模板：

替换后效果：

代码：

1、入口文件

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
