바. jsp 에서 정적파일 사용하기 (js, css, image)
- 정적파일은 src/main/resources/static 폴더에 저장해야 된다.
a. static 폴더 작성
src/main/resources/
ㄴstatic
ㄴjs
ㄴtest.js
ㄴcss
ㄴtest.css
ㄴimages
ㄴthymeleaf.png
b. jsp 사용
<head>
...
<link rel="stylesheet" href="css/test.css">
<script src="js/test.css"></script>
</head>
<body>
...
<img src="images/thymeleaf.png" width="100" height="100">
</body>
