版权过滤器

摘要: 版权过滤器

</td> </tr> <tr> <td height="35" valign="top" class="ArticleTeitle"> 一般我们都会在网页（仅指*.jsp和servlet）尾部加上版权标志，大都采用添加include指令 <%@ include file="tail.jsp" %>或
标记，其实用过滤器是不是更好？

<table width="669" border="0"> <tr> <td width="395"> package example;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class CopyrightFilter implements Filter{
private FilterConfig config;
String year;

public void init(FilterConfig config) throws ServletException{
this.config=config;
year=config.getInitParameter("date");
} </td> <td width="264"> </td> </tr> </table>
public void doFilter(ServletRequest req,ServletResponse resp,FilterChain chain) throws IOException,ServletException{
chain.doFilter(req,resp);
PrintWriter out=resp.getWriter();
out.println("
版权所有：java学习室"+year+"");
out.flush();
}

public void destroy(){}

}
最后要在web.xml中添加：

CopyrightFilter

example.CopyrightFilter

date

2004.9

CopyrightFilter

function TempSave(ElementID) { CommentsPersistDiv.setAttribute("CommentContent",document.getElementById(ElementID).value); CommentsPersistDiv.save("CommentXMLStore"); } function Restore(ElementID) { CommentsPersistDiv.load("CommentXMLStore"); document.getElementById(ElementID).value=CommentsPersistDiv.getAttribute("CommentContent"); } </td> </tr> <tr>
