一个网站转向的JavaBean

以下是java源码ReturnTo.java

package com.lzpc.common;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
/*
自动转向javabean
*/
public class ReturnTo extends HttpServlet
{
private String Msg;
private String Rurl;
private boolean isA;
public void setMsg(String inMsg)
{
this.Msg=inMsg;
}
public void setRurl(String inRurl)
{
this.Rurl=inRurl;
}
public void setIsA(boolean inisA)
{
this.isA=inisA;
}
public String getMsg()
{
return this.Msg;
}
public String getRurl()
{
return this.Rurl;
}
public boolean getIsA()
{
return this.isA;
}
public void go(HttpServletResponse response)
throws IOException, ServletException
{
PrintWriter out = response.getWriter();
out.print("<script language='javascript'>");
if (this.isA)
{
out.print("alert('"+ Msg + "!');");
}
out.print("location.href='"+Rurl+"';");
out.print("</script>");
}
}

应用test.jsp

<%@ page contentType="text/html;charset=GBK"%>
<jsp:useBean id="we" scope="page" class="com.lzpc.common.ReturnTo" />
<%
String Msg="网站正在转向中,请稍等";
String Url="http://www.lzpc.net/";
we.setMsg(Msg);
we.setRurl(Url);
we.setIsA(true);
we.go(response);
%>

注释说明:

1:保存文件位置

ReturnTo.java ===>tomcat5.8/webapps/ROOT/WEB-INF/classes/com/lzpc/common

test.jsp 放到tomcat5.8/webapps/ROOT下,

2,写了这个Bean在运用网站转向时就不用写这么多的javascript代码:)

3,在tomcat5.8 + jdk1.5 + winXP 下测试通过.
