Thymeleaf定义和引用模板及include和replace的区别

一、定义模板

可通过th:fragment定义模板片段和id定义模板片段

th:fragment的值为模板片段的名称

One通过th:fragmen定义模板片段；

Two通过id定义模板片段；

Three和four为了引用时，显示include和replace的区别；

Five模板片段传参。

myfrag.html

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<body>
    <div th:fragment="One">
        This is One!
    </div>
    <div id="Two">
        This is Two!
    </div>
    <div th:fragment="Three" style="background: deepskyblue">
        This is Three!
    </div>
    <div th:fragment="Four" style="background: deepskyblue">
        This is Four!
    </div>
    <div th:fragment="Five(onevar,twovar)">
        <p th:text="${onevar} + ' - - - - - ' + ${twovar}"></p>
    </div>
    <div th:fragment="Six">
        This is Six!
    </div>
    <div th:fragment="Seven">
        This is Seven!
    </div>
</body>
</html>

二、引用模板

用th:include或th:replace引入模板

其值为"模板名称::片段"

index.html

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
</head>
<body>
    <div th:include="myfrag::One"></div>
    <div th:include="myfrag::#Two"></div>
    <div th:include="myfrag::Three" style="background: red"></div>
    <div th:replace="myfrag::Four" style="background: red"></div>
    <div th:include="myfrag::Five ('ThisOne','ThisTwo')"></div>
    <div th:include="myfrag::Six" style="background: red"></div>
    <div th:replace="myfrag::Seven" style="background: red"></div>
</body>
</html>

三、include和replace的区别

include是本div包含引入div的内容

replace是本div替换引入div

定义模板如：

<div th:fragment="frag1" id="frag1" >
	frag1
</div>
<div th:fragment="frag2" id="frag2">
	frag2
</div>

引入模板如：

<div th:include="myfrag::frag1" id="inc"></div>
<div th:replace="myfrag::frag2" id="rep"></div>

相当于：

<div id="inc">frag1</div>
<div id="frag2">frag2</div>

四、传参
