网上介绍的方法都挺好，网上一搜也一大把，我用的是制作模板的那个方法，还挺好用的，现在分享一下。

先找一个教程，制作一个模板，然后就是测试：

代码它来了，

public class WordTest {  
      
    private Configuration configuration = null;  
      
    public WordTest(){  
        configuration = new Configuration();  
        configuration.setDefaultEncoding("UTF-8");  
    }  
      
    public static void main(String[] args) {  
        WordTest test = new WordTest();  
        test.createWord();  
    }  
      
    public void createWord(){  
        Map<String,Object> dataMap=new HashMap<String,Object>();  
        getData(dataMap);  
        configuration.setClassForTemplateLoading(this.getClass(), "");//模板文件所在路径
        Template t=null;  
        try {  
            t = configuration.getTemplate("测试.ftl"); //获取模板文件
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
        File outFile = new File("D:/outFile"+Math.random()*10000+".doc"); //导出文件
        Writer out = null;  
        try {  
            out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));  
        } catch (FileNotFoundException e1) {  
            e1.printStackTrace();  
        }  
           
        try {  
            t.process(dataMap, out); //将填充数据填入模板文件并输出到目标文件 
        } catch (TemplateException e) {  
            e.printStackTrace();  
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
    }  
  
    private void getData(Map<String, Object> dataMap) {  
        dataMap.put("title", "标题");  
        dataMap.put("nian", "2016");  
        dataMap.put("yue", "3");  
        dataMap.put("ri", "6");   
        dataMap.put("shenheren", "lc");  
          
        List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();  
        for (int i = 0; i < 10; i++) {  
            Map<String,Object> map = new HashMap<String,Object>();  
            map.put("xuehao", i);  
            map.put("neirong", "内容"+i);  
            list.add(map);  
        }  
          
          
        dataMap.put("list", list);  
    }  
}

成了。

还可以直接输出到浏览器。

只需要添加

response.setContentType("application/x-msdownload;");
response.addHeader("Content-Disposition", "attachment;filename="+ URLEncoder.encode("文件名", "UTF-8") + ".doc");

然后其中的createWord()方法就成了下面这个代码：

 public void createWord(HttpServletResponse resp){  
        Map<String,Object> dataMap=new HashMap<String,Object>();  
        getData(dataMap);  
        configuration.setClassForTemplateLoading(this.getClass(), "");//模板文件所在路径
        Template t=null;  
        try {  
            t = configuration.getTemplate("测试.ftl"); //获取模板文件
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
        //File outFile = new File("D:/outFile"+Math.random()*10000+".doc"); //导出文件
        Writer out = null; 
        response.setContentType("application/vnd.ms-excel");  
        response.addHeader("Content-Disposition", "attachment;filename="+ URLEncoder.encode("文件名", "UTF-8") + ".doc"); 
        try {  
            //out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile)));  
              out = new BufferedWriter(new OutputStreamWriter(response.getOutputStream()));  
        } catch (FileNotFoundException e1) {  
            e1.printStackTrace();  
        }  
           
        try {  
            t.process(dataMap, out); //将填充数据填入模板文件并输出到目标文件 
        } catch (TemplateException e) {  
            e.printStackTrace();  
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
    }
