resin下 response.sendRedirect("XXX"); 会报异常:java.lang.IllegalStateException: Can't sendRedirect() after data has committed to the client. 原因是在做登陆时用户名和密码判断后,做的页面跳转有问题,按照异常来理解,应该是服务器已经返回了状态200或者404或者其他的状态码,但是又执行了重定向的代码,返回302状态码.服务器同一次相应应该只返回一种状态,res…

java servlet 几种页面跳转的方法及传值   java web 页面之间传值有一下这几种方式1.form 表单传递参数2.url地址栏传递参数3.session4.cookie5.application 6.通过隐藏域传值 7.通过JavaBean进行传值 8. request.setAttribute("strRequest", strRequest); 9.response.setAttribute("name",name)来传至下一个页面 10.re…
一.Servlet:当然,在servlet中,一般跳转都发生在doGet, doPost等方法里面.1)  redirect 方式response.sendRedirect("success.jsp");页面的路径是相对路径.sendRedirect可以将页面跳转到任何页面,不一定局限于本web应用中,如:response.sendRedirect("http://www.ycul.com");跳转后浏览器地址栏变化.这种方式要传值出去的话,只能在url中带para…
背景:       自己经手的一个java项目要实现带参页面跳转和页面跳转,完成任务后,总结一下自己知道了的几种方式. 实现: 首先我们有两大种方式来实现页面跳转:1.JS(javascript):2.jsp跳转 我们先来说一下简单的js实现页面跳转:好几种,这里简单介绍3个 1.window.location.href="URL";        2.window.navigate("URL")        3.window.location.replace(&…

一直对Servlet页面跳转的几种方式理解的糊里糊涂的,今天在网上搜了一把,找到一遍比较好的,记下来,以后看看. Servlet页面跳转分两部分,一是发生在Servlet,一是在JSP,其实JSP也就是servlet,不过还是有点差异滴. Servlet: 当然,在servlet中,一般跳转都发生在doGet, doPost等方法里面. 1)  redirect 方式 response.sendRedirect("/a.jsp"); 页面的路径是相对路径.sendRedirect可以将…
一.调用方式 我们知道,在servlet中调用转发.重定向的语句如下: request.getRequestDispatcher("new.jsp").forward(request, response);   //转发到new.jsp response.sendRedirect("new.jsp");   //重定向到new.jsp 在jsp页面中你也会看到通过下面的方式实现转发: <jsp:forward page="apage.jsp"…

前言: 在使用solidity写智能合约的时候,会使用到revert和require来进行断言,比如: require(tokenOwner[tokenId] == 0x0,'this is not the first create'); 在上面的断言中,只有当你满足了tokenOwner[tokenId] == 0x0这个 条件,你才能继续往下执行,否则就会报错“this is not the first create”. 然后当我们使用remix这个编译器的时候,是能够在出错的时候得到rea…

HttpServletResponse重定向 1.HTTP协议规定了一种重定向的机制,重定向的运作流程如下 用户在浏览器输入特定的URL,请求访问服务端的某个组件. 服务端的组件返回一个状态码为302的响应结果.该响应结果的含义为:让浏览器在请求访问另一个Web组件.在响应结果中 提供了另一个组件的URL. 当浏览器端接收到这种响应结果后,再立即自动请求访问另一个Web组件 浏览器接收到来自另一个Web组件的响应结果 2. 在JAVA Servlet API中 用于重定向的HttpServlet…
