poi 生成word打不开，求大神帮忙

///////////////////测试导出word
public void testWrite() throws Exception {

try {
String templatePath = "D:\innerPlatform\addition\format\temp.doc";

InputStream is = new FileInputStream(templatePath);

HWPFDocument doc = new HWPFDocument(is);

Range range = doc.getRange();

//把range范围内的${reportDate}替换为当前的日期

range.replaceText("${reportDate}", new SimpleDateFormat("yyyy-MM-dd").format(new Date()));

range.replaceText("${appleAmt}", "100.00");

range.replaceText("${bananaAmt}", "200.00");

range.replaceText("${totalAmt}", "300.00");

OutputStream os = new FileOutputStream("D:\word\writexx.doc");

//把doc输出到输出流中

doc.write(os);

this.closeStream(os);

this.closeStream(is);

    } catch (Exception e) {
        e.printStackTrace();
    }

   } 


   /** 
    * 关闭输入流 
    * @param is 
    */  
   private void closeStream(InputStream is) {  
      if (is != null) {  
         try {  
            is.close();  
         } catch (IOException e) {  
            e.printStackTrace();  
         }  
      }  
   }  

   /** 
    * 关闭输出流 
    * @param os 
    */  
   private void closeStream(OutputStream os) {  
      if (os != null) {  
         try {  
            os.close();  
         } catch (IOException e) {  
            e.printStackTrace();  
         }  
      }  
   }  

打不开是点都点不动还是打开乱码？

请问解决了吗
