1. Thymeleaf 기본 표현

자세한 문법은 Thymeleaf 사이트의  튜토리얼을 참고하는게 좋습니다. 

• 기본 표현, 
• 조건문, 
• 반복문

세가지를 중점으로 보겠습니다.

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>
