額外篇：儲存html內容到資料庫，點選開啟連結

一、js傳送讀取html內容請求

var url = "...", data = {id:".."};
$.ajax({
          url: url,
          type : "post",
        data : data,
          dataType: "json",
          success: function(data, textStatus, jqXHR){
              //返回html內容結果，並顯示到當前頁面
          
                var htmlContent = data;
                window.document.body.innerHTML = "";
                //document.close();
                document.write(htmlContent);
                       
          },
          error : function(jqXHR, textStatus, errorThrown){
              alert(jqXHR + "," + textStatus + "," + errorThrown);
          }
    });
 

String sql = "...";
List<Map<String, Object>> lists =
        jdbcTemplate().query(sql, new RowMapper<Map<String,Object>>(){
            @Override
            public Map<String,Object> mapRow(ResultSet rs, int rowNum) throws SQLException {
                Map<String,Object> row = new HashMap<String,Object>();
                row.put("CONTENT", lobHandler.getBlobAsBinaryStream(rs, "CONTENT"));//欄位CONTENT是BLOB型別
                return row;
            }});
String htmlContent = null;           
InputStream inputStream = null;
try{
    inputStream = (InputStream) files.get(0).get("CONTENT");
    htmlContent = IOUtils.toString(inputStream);//IOUtils是commons-io.jar的一個類
}finally{
    if(inputStream != null) inputStream.close();
}

return htmlContent;
