动态设置路由标题title；动态设置路由配置meta；独享的守卫beforeEnter

案例：同一个页面即使新增，又是编辑、详情页。导致路由配置里的title无法固定
通过路由的独享的守卫beforeEnter解决配置；同时beforeEnter一定程度上可以帮助处理vue3缓存问题

      {path: "methodApplicationFormOperate",name: "MethodApplicationFormOperate",meta: { title: "新增申请单", forceUseTitle: true },component: () => import("@/views/communicationManagement/methodApplicationForm/methodApplicationFormOperate.vue"),beforeEnter: (to, from, next) => {console.log('beforeEnter==', to, from, next);if (to.query.editType == "edit") {to.meta.title = "编辑申请单"to.matched[to.matched.length - 1].meta.title = "编辑申请单"} else if (to.query.editType == "add") {to.meta.title = "新增申请单"to.matched[to.matched.length - 1].meta.title = "新增申请单"} else {to.meta.title = "申请单详情"to.matched[to.matched.length - 1].meta.title = "申请单详情"}next()},},
