結果補的速度還是跟不上倒數的日期

這裡開始要練習調整angular的routes中文是寫"路由"->按鈕可以跳頁0.0

也會加入 SpringBoot REST方法@Query:

從增加path開始~

import {Routes, RouterModule} from '@angular/router';

const rotutes:Routes =[
  {path:'category/:id',component: ProductListComponent},
]

複製{path:'category/:id',component: ProductListComponent},語法

加上 {path:'',redirectTo:'prouducts',pathMatch:'full'},
是為了符合所有的語法

import { ProductService } from './services/product.service';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { ProductListComponent } from './components/product-list/product-list.component';
import { HttpClientModule } from '@angular/common/http';


import {Routes, RouterModule} from '@angular/router';

const rotutes:Routes =[
  {path:'category/:id',component: ProductListComponent},
  {path:'category',component: ProductListComponent},
  {path:'prouducts',component: ProductListComponent},

  {path:'',redirectTo:'prouducts',pathMatch:'full'},
  {path:'**',redirectTo:'prouducts',pathMatch:'full'},


]

@NgModule({
  declarations: [
    AppComponent,
    ProductListComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [ProductService],
  bootstrap: [AppComponent]
})
export class AppModule { }

import路由RouterModule.forRoot(rotutes),

import { ProductService } from './services/product.service';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { ProductListComponent } from './components/product-list/product-list.component';
import { HttpClientModule } from '@angular/common/http';


import {Routes, RouterModule} from '@angular/router';

const rotutes:Routes =[
  {path:'category/:id',component: ProductListComponent},
  {path:'category',component: ProductListComponent},
  {path:'prouducts',component: ProductListComponent},

  {path:'',redirectTo:'prouducts',pathMatch:'full'},
  {path:'**',redirectTo:'prouducts',pathMatch:'full'},


]

@NgModule({
  declarations: [
    AppComponent,
    ProductListComponent
  ],
  imports: [
    RouterModule.forRoot(rotutes),

    BrowserModule,
    HttpClientModule
  ],
  providers: [ProductService],
  bootstrap: [AppComponent]
})
export class AppModule { }

到app.component.html這個檔案

來編寫側邊欄-"路由"部分<router-outlet></router-outlet>

刪掉

剩下的程式碼:

<div class="page-wrapper">

  <!-- MENU SIDEBAR-->
  <aside class="menu-sidebar d-none d-lg-block">

      <a href="#">

    <div class="menu-sidebar-content js-scrollbar1">

    <li><a href="#">About Us</a></li>
    <li><a href="#">Contact Us</a></li>
    <li><a href="#">Help</a></li>
  </ul>
</footer>

也刪掉

<li>
            <a href="#">Mouse Pads</a>
          </li>
          <li>
            <a href="#">Luggage Tags</a>
          </li>

把Books的href="#"作變更

 <a routerLink="/category/1" routerLinkActive="active-link">Books</a>

有路由的連結
到product-list.component.ts這個檔案

延續昨天的閒聊

等我更新之後這裡的內容就會刪掉了喔
Apache NetBeans IDE 10.0安裝

用右鍵notepad++打開來看
手動加入netbeans_jdkhome="C:\Program Files\Java\jdk-11.0.8"

桌面建立捷徑

桌面點2下選NO-因為JDK我們已經選好了

新增專案-

選Download

選NEXT

打V和Install

在原來的地方新打入10

圈起來的地方新增

2020.9.24時還不能用來寫JAVA EE

結果

DEAR ALL 我們明天見
