/*路由基本模型*/

/*定义路由const表示不可改变*/
const routers: Routes = [
 /*
  path：字符串，表示默认登入,
  path为路径 /login component:组件
  component：组件
  pathMatch：为字符串默认为前缀匹配 "prefix"; "full" 为完全匹配。
  redirectTo：指向为路径，既path
  outlet：字符串，路由目标，面对多个路由的情况
  children：Routes 子路由相关
  */
 { path: '', component: LoginComponent },
 // path:路径 /detail/1 :id代表参数相关
 { path: 'detail/:id', component: LoginComponent },
 // 懒加载子模块, 子模块需要配置路由设置启动子组件，如果这样设置了路由，需要在子模块中再定义路由
 { path: 'other', loadChildren:"./demo/demo.module#demoModule" },
 // 重定向，路径为** 表示不能识别的路径信息，重定向到相关路径下
 { path: '**', pathMatch: 'full', redirectTo: '' }

路由配置




{
 path: ...,
 canDeactivate: [DeacService],
  component: ...
}



模块中添加服务




providers: [
 DeactivateGuardService
]
