한참 전에 공부한답시고 엄청 지저분하지만 돌아가는, 그런 소스로 짠 적이 있었다.
이번엔 좀 더 확실히 더 많은 기능을 넣고, 에러도 잘 나지 않는 그런 프로그램을 구현해보려고 만들었다.
예전엔 3일이나 걸려서 만들었던 프로그램이지만 다시 만드니 2시간이면 기능, 대부분의 GUI까지 구현이 끝나는 것을 볼 수 있었다.
크롤러 특성상 사이트 의존성이 매우 강하기 때문에 이 크롤러는 zerochan,net 의 이미지만을 긁어올 수 있다.
다음이 소스이다.

크롤러 클래스를 만들어서 넣어 두었다.
총 4개의 Thread를 만들어서 크롤링을 하며, 우선적으로 페이지들을 돌며 이미지들의 주소를 받아오고,
이 주소에 각각 Thread를 할당하여 다운받아오는 방식이다.
다음은 GUI 인터페이스이다.

사실상 이거 짜는게 제일 오래 걸렸다.
크게 어려운 건 없었지만 노가다라고 해야 하나, 역시 코딩은 열심히 두들기는게 답이었다.
다음은 시연 영상이다.
(혹시라도 문제가 된다면 삭제하도록 하겠습니다)
