JSP页面的关键在于

1 isErrorPage="true"

2 response.setStatus(HttpServletResponse.SC_OK);

building.jsp

 

 1 <% @ page language = " java "  contentType = " text/html; charset=GBK "  isErrorPage = " true "  pageEncoding = " GBK " %>
 2 <% response.setStatus(HttpServletResponse.SC_OK); %>
 3 <%
 4 /** */ /**
 5* 本页面是在客户查找的页面无法找到的情况下调用的
 6*/
 7 response.setStatus(HttpServletResponse.SC_OK);
 8 %>
 9 < body >
10 正在制作  < a href = " javascript:history.go(-1) " > 返回 </ a >
11 < br />
12 也可能页面连接更改了，请按 F5 键刷新整个页面看看，特别是菜单！
13 </ body >

 

error.jsp

 1 <% @ page language = " java "  contentType = " text/html; charset=GBK "  isErrorPage = " true "  pageEncoding = " GBK " %>
 2 <% @ page  import = " java.io.*,java.util.* " %>
 3 <% response.setStatus(HttpServletResponse.SC_OK); %>
 4 < body >
 5 程序发生了错误，有可能该页面正在调试或者是设计上的缺陷. < br />
 6 你可以选择 < br />   < a href =<%= request.getContextPath() + " /forum/new.jsp "   %>> 反馈 </ a >
 7 提醒我 或者 < br />< a href = " javascript:history.go(-1) " > 返回上一页 </ a >
