将后台数据传到前台JSON应用

先看看源代码：

_page=voucher4TestCSharp.queryForPagePDF(admdivcode,styeay, 
        		vtcode,star_voucherno,curPage, pageSize);
        	
        if(_page!=null){
        	list = _page.getResultList();
        }
        listMap = new ArrayList<Map<String,String>>();
        
     	for(VoucherDTO_PDF newVoucherDTO_PDF:list){
     		Map<String,String> map = null;
     		map = BeanUtils.describe(newVoucherDTO_PDF);
     		
     		String voucher_no=newVoucherDTO_PDF.getVoucher_no();
     		String quhua_code=newVoucherDTO_PDF.getAdmdivcode();
     		String vt_code=newVoucherDTO_PDF.getVt_code();
     	    String styear=newVoucherDTO_PDF.getStyear();
     	    
     		map.put("download", "<a href=javascript:download('"+voucher_no+"','"+quhua_code+"','"+vt_code+"','"+styear+"')>下凭证载</a>");
      		listMap.add(map);
     	}

		Map<String,List<Map<String,String>>> resultMap = new HashMap<String,List<Map<String,String>>>();
		resultMap.put("data", listMap);
		
		JSONObject jo = JSONObject.fromObject(resultMap);
		jo.put("recordCount", _page.getTotalRows());
		this.actionWrite(jo.toString());
		return null;_page=voucher4TestCSharp.queryForP
