Spring boot - Thymeleaf 기본 문법

2023. 5. 18. 17:08ㆍ카테고리 없음

1. Thymeleaf 기본 표현

자세한 문법은 Thymeleaf 사이트의 튜토리얼을 참고하는게 좋습니다.

기본 표현,
조건문,
반복문

Thymeleaf Document 참고

(https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html#standard-expression-syntax)

Simple expressions:
Literals
- Text literals: 'one text', 'Another one!',…
- Number literals: 0, 34, 3.0, 12.3,…
- Boolean literals: true, false
- Null literal: null
- Literal tokens: one, sometext, main,…
Text operations:
- String concatenation: +
- Literal substitutions: |The name is ${name}|
Arithmetic operations:
- Binary operators: +, -, *, /, %
- Minus sign (unary operator): -
Boolean operations:
- Binary operators: and , or
- Boolean negation (unary operator): ! , not
Comparisons and equality:
- Comparators: > , < , >= , <= ( gt , lt , ge , le )
- Equality operators: == , != ( eq , ne )
Conditional operators:
- If-then: (if) ? (then)
- If-then-else: (if) ? (then) : (else)
- Default: (value) ?: (defaultvalue)

2. 자주 사용하는 문법 및 표현식 예제

표현식 : th:[속성]="서버 전달 받은 값 또는 조건식"

Tag 안에 삽입되면 된다.

Thymeleaf 3.x 에서는 inline 표현식이 추가되어 html 태그없이 표현이 가능하다.

[[$user.name]]

TitleDescription

th:text	텍스트 내용 <span th:text="${user.name}"></span>
th:utext	html 내용 <div th:utext="${content}"></div>
th:value	element value값, checkbox, input 등 <input type="text" th:value="${title}" />
th:with	변수값 지정 <p th:with="authType = ${user.authType}+' Type'" th:text="${authType}"></p>
th:switch th:case	switch-case문 <div th:switch="${user.role}"> <p th:case="'admin'">User is an administrator <p th:case="#{roles.manager}">User is a manager </div>
th:if	조건문 <p th:if="${user.authType}=='web'" th:text="${user.authType}"></p>
th:unless	else 표현 <p th:unless="${user.authType}=='facebook'" th:text="'not '+ ${user.authType}"></p>
th:each	반복문 <p th:each="user : ${users}" th:text="${user.name}"></p>
