[Kotlin + Spring] Maven configuration

Posted at 2019.05.26 11:55 | Posted in Java+/Trouble Shooting

Problem

Kotlin 1.3 이상을 사용하면서 스프링 부트 메인 클래스는 open 키워드를 넣어줘야 하는 가벼운(?) 이슈가 있었었다...

이번에는 spring-data + Mongodb를 공부하면서 다시 이 이슈가 등장하였다.

Kotlin + Spring 하면서 코틀린의 class 가 final로 되는 부분과 스프링에서 빈을 처리하기위해 클래스를 까발리는(?) 부분에서 문제가 생긴다. final class 는 조작이 안되기 때문에!?

Installation Vue.js (Eclipse)

Posted at 2018.05.24 21:32 | Posted in Study/Vue.js

Introduction


Eclipse 에서 Vue.js 개발 환경을 구축해보자.




Preparation


이클립스는 JavaScript and Web Developers 패키지로 받았다.




npm을 어디서든사용할 수 있도록 nodejs를 받아서 Path 환경 변수에 등록하자.





Install CodeMix Plugin


Eclipse Marketplace(Help - Eclipse Marketplace...)에서 vue를 검색하면 플러그인이 나온다. (하나만 있는듯? -_-)


With CodeMix, unlock a wide array of technologies from Visual Studio Code and add-on extensions built for Code OSS directly inside your Eclipse IDE.


- First class JavaScript coding & debugging

- Vastly improved HTML and CSS editing

- New languages including TypeScript, PHP and Python

- New frameworks from React and Vue.js to Angular

- New UX patterns like the Quick Open shortcuts

- As-you-type content assist




라이선스.. 네네...




설치 후 재시작 해준다.




재시작 하면 CodeMix 에 대한 설명+설정이 나온다.







Create Vue project


File - New - Project




프로젝트 이름 입력 후 Finish




아래와 같은 구조로 프로젝트가 만들어진다.




프로젝트에서 마우스 오른쪽 버튼 - Run As - npm Install 클릭.




프로젝트에 필요한 모듈들을 설치하게 된다.

> node lib/post_install.js


> node-sass@4.9.0 postinstall D:\dev\workspace\vue.js\node_modules\node-sass
> node scripts/build.js

Binary found at D:\dev\workspace\vue.js\node_modules\node-sass\vendor\win32-x64-57\binding.node
Testing binary
Binary is fine
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

added 891 packages in 151.496s

D:\dev\workspace\vue.js>exit


node_modules 라는 디렉터리가 생성되고 하위에 필요한 모듈들이 들어있다. (이 디렉터리는 VCS에 포함시키지 말자!)




package.json - dev 에서 마우스 오른쪽 버튼. Run As - npm Script




아래와 같이 Console이 나오게 된다.


Microsoft Windows [Version 10.0.16299.309]
(c) 2017 Microsoft Corporation. All rights reserved.

D:\dev\workspace\vue.js>npm run-script dev

> vue-hello-world@1.0.0 dev D:\dev\workspace\vue.js
> cross-env NODE_ENV=development webpack-dev-server --open --hot

Project is running at http://localhost:8080/
webpack output is served from /dist/
404s will fallback to /index.html



브라우저가 자동으로 실행되고 아래와 같이 나온다면 성공!

Installation Vue.js (WebStorm + Vue CLI)

Posted at 2018.05.21 13:22 | Posted in Study/Vue.js

Introduction


WebStorm + Vue CLI를 이용해서 Vue.js 개발 환경을 구축해보자.


Vue.js는 단일 페이지 응용 프로그램을 빠르게 스캐폴딩하기 위한 공식 CLI를 제공합니다. 현대적인 프론트엔드 워크플로우를 위해 잘 구성된 빌드 설정을 제공합니다. 핫 리로드, lint-on-save 및 프로덕션 준비가 된 빌드로 시작하고 실행하는데 몇 분 밖에 걸리지 않습니다.


처음 CLI 를 접하기 전에 사전 지식을 필요로 하니 당장 Vue.js 만 공부하려면 순수 HTML, CSS, Javascript 로 구성해서 학습하는 것도 괜찮을 것 같다. (난 사전 지식 없는데 왜 이걸로 하고 있지... ㅠㅠ)


CLI는 Node.js 및 관련 빌드 도구에 대한 사전 지식을 필요로 합니다. Vue 또는 프런트엔드 빌드 도구를 처음 사용하는 경우 CLI를 사용하기 전에 빌드 도구없이 가이드를 읽어 보시기 바랍니다.




Preparation


Node.js가 필요하다. 다운로드 받은 후 환경변수 PATH 등록 해두자.



vue-cli 를 설치한다.


D:\>npm install --global vue-cli
npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
D:\develoment\tools\node-v8.11.2-win-x64\vue-list -> D:\develoment\tools\node-v8.11.2-win-x64\node_modules\vue-cli\bin\vue-list
D:\develoment\tools\node-v8.11.2-win-x64\vue -> D:\develoment\tools\node-v8.11.2-win-x64\node_modules\vue-cli\bin\vue
D:\develoment\tools\node-v8.11.2-win-x64\vue-init -> D:\develoment\tools\node-v8.11.2-win-x64\node_modules\vue-cli\bin\vue-init
+ vue-cli@2.9.3
added 258 packages in 27.115s




Create Vue.js Project


WebStorm 실행 후 프로젝트를 새로 생성한다.




Location: 프로젝트의 디렉터리

Node interpreter : node.exe 파일의 위치

vue-cli or @vue/cli: vue-cli 모듈의 위치. 위에서 vue-cli 를 설치 했으면 자동으로 인식 된다.

Project template: 만들어질 프로젝트 기본 템플릿 6가지

  • browserify : hot-reload, linting 및 단위 테스팅 등 대부분의 기능을 갖춘 Browserify + vueify 설정.
  • browserify-simple : 단순히 Browserify와 vueify만 포함. 빠르게 프로토타입을 만들 때 사용한다.
  • pwa : ot-reload, linting, 테스트 및 CSS 추출 기능을 갖춘 대부분의 기능을 갖추고 있는 Webpack + PWA 템플릿.
  • simple : 가장 단순하게 한 HTML 파일에 Vue 설정을 담고 있다.
  • webpack : hot-reload, linting, 테스트 및 CSS 추출 기능을 갖춘 대부분의 기능을 갖추고 있는 Webpack + vue-loader 설정.
  • webpack-simple : 단순히 Webpack과 vue-loader만 포함한다. 빠르게 프로토타입을 만들 때 사용한다.




프로젝트 이름...




프로젝트 설명...




작성자 이름...




Vue build

  • Runtime + Compiler : 일반 적인 대부분 사용자에게 권한다.
  • Runtime-only : 약 6KB 안되는 용량. 하지만 템플릿(.vue)만 사용할 수 있다.

개발 중에는 최소화 버전을 사용하지 마십시오. 일반적인 실수에 대한 모든 훌륭한 경고를 놓치게됩니다!


현재는 개발(공부) 용도이기 때문에 Runtime + Compiler 선택...




해시(#) URL이나 HTML5 History 등을 이용하여 SPA에서 페이지 네비게이션 기능을 vue.js에서 사용하고 싶을 때 쓰는 vue-router 모듈을 설치할 것인지 여부이다.




자바스크립트 코딩 스타일과 에러를 체크하는 ESLint를 사용할 지 여부.




ESLint 를 사용한다면 어떤 코딩 스타일 세팅(preset)을 사용할지 선택하는 단계이다.




단위 테스트를 사용할 지 여부.




어떤 테스트기(test runner)를 사용할 지 선택한다.




Nightwatch를 이용하여 e2e(End-to-End) 테스트를 할 수 있도록 설정할 것인지 여부.




프로젝트가 생성된 후에 NPM 을 사용할 것인지 물어본다...




이제 프로젝트가 만들어졌다.


IDE 우측 하단의 알람을 보면 종속 모듈을 설치해야 한다고 한다. Run 'npm install' 을 클릭 하거나 Terminal 에서 직접 커맨드를 입력해서 설치하면 된다.



Terminal 에서 직접 npm install 했을 때 내용은 대충... 아래와 같다.
