在Servlet中有一段代码如下
publicvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
request.setAttribute("name",newInteger(100));
response.sendRedirect("show.jsp");
}
在show.jsp中
<%=request.getAttribute("name")%>
页面结果为
publicvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
request.setAttribute("name",newInteger(100));
response.sendRedirect("show.jsp");
}
在show.jsp中
<%=request.getAttribute("name")%>
页面结果为
