一，添加pom.xml文件依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>2.4.1</version>
</dependency>
二，如下两个文件代码
index.html引用模板文件,PS:(layout:decorate="testlayout/layout",这个必须注意，模板文件的地址)
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorate="~{testlayout/layout}"> <head lang="en"> <title>Search</title> </head> <body> <div class="row" layout:fragment="content"> <h4 class="indigo-text center">中间部分e</h4> </div> </body> </html>
模板文件
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no" /> <title>Insert title here</title> </head> <body> <div> <div th:replace="/testlayout/test::nav"></div> </div> <section layout:fragment="content"> <p>Page content goes here</p> </section> <div> 尾部 </div> </body> </html>
test.html导航文件代码，PS:<div th:replace="/testlayout/test::nav"></div>注意这个地址，不能写错，我的文件都是在testlayout这个文件目录下的
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <body> <div th:fragment="nav"> <nav> <ul class="columnbar"> <li><a href="/#">首页</a></li> <li><a href="/#">首页</a></li> <li><a href="/#">首页</a></li> <li><a href="/#">首页</a></li> <li><a href="/#">首页</a></li> </ul> </nav> </div> </body> </html>
