struts的声明式异常处理demo

这时候就要用到声明式异常处理了 类似于web.xml中的error-page配置 声明式异常处理 声明式异常处理要用到两个标签exception-mapping和result 先放上刚刚解决方案的代码 notFound exception-mapping的result,先检查当前action内的result是否有匹配的(如果是就直接检查),如果匹配上了,就执行result的内容,像正常的action返回result那样 在这里,就是返回了notFound 的result,然后找到global-results里有一个叫做notFound的result,然后执行重定向notFoundnotFound是一个action 注意,如果result返回了一个action

    官方路由:对于大多数单页面应用,都推荐使用官方支持的vue-router库,可能在使用vue-router的时候,我们并不了解其原理,官网也提供的一个完整的例子如下:const NotFound = { , data: { currentRoute: window.location.pathname }, computed: { ViewComponent () { return routes || NotFound Vue from vueimport routes from .routesimport About from .viewsAboutimport Home from .viewsHomeimport NotFound this.currentRoute) return h(Home) } else if (this.currentRoute == about) { return h(About) } } else { return h(NotFound

    react 同构初步(4)

    现在把Index的匹配去掉,增加404NotFound组件: App.jsimport NotFound from .containerNotFound;export default 404页面: containerNotFound.jsimport React from react; function NotFound(props){ return 404 你来到了没有知识的星球.. } export default NotFound;然后在header组件中加上一条404路由:404刷新,看到了404的请求:? () { return ( Sorry, can’t find that. );} function App() { return ( );} 你可以传递一个全局的context对象给你创建的notfoundNotfound中定义一个Status组件用来给staticContext赋值:import React from react;import { Route } from react-router-dom
