  • 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.*;
