Java读取根据HTML模板生成HTML页面

首先，我们需要一个html模板：

  1. <html>
  2. <head>
  3. <title>###title###</title>
  4. <meta http-equiv="Content-Type" content="text/html; charset=gbk">
  5. </head>
  6.  
  7. <body>
  8. <table width="500" border="0" align="center" cellpadding="0" cellspacing="2">
  9. <tr>
  10. <td align="center">###title###</td>
  11. </tr>
  12. <tr>
  13. <td align="center">###author### </td>
  14. </tr>
  15. <tr>
  16. <td>###content###</td>
  17. </tr>
  18. <tr>
  19. <td>###html###</td>
  20. </tr>
  21.  
  22. </table>
  23. </body>
  24. </html>

其次：我们编写java代码实现模板读取，页面生成：

  1. import javax.servlet.http.HttpServletRequest;
  2. import java.util.List;
  3. import java.util.ArrayList;
  4. import java.util.Date;
  5. import java.net.URL;
  6. import java.net.URLConnection;
  7. import java.io.*;
