1、简介
thymleaf是一个基于html的页面模板，springboot极力推荐使用它，代替jsp。
API地址：https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html#introducing-thymeleaf
2、使用
1）添加依赖
<!--thymleaf--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
2）在templates下添加一个html，将文档声明为thymleaf文档：
<html xmlns:th="http://www.thymeleaf.org">
3）写一个控制器
package com.biniu.controller; import org.apache.catalina.servlet4preview.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; /** * @author lay * @date 2018/4/15. * @time 12:53 */ @Controller public class IndexController { @RequestMapping(value = {"", "index"}) public String index(HttpServletRequest request, Model model) { // 属性 model.addAttribute("properties", "properties value"); // 对象 Map<String, Object> person = new HashMap<>(); person.put("name", "lay"); model.addAttribute("person", person); // 列表 List<Map<String, Object>> persons = new ArrayList<>(); persons.add(person); persons.add(person); persons.add(person); model.addAttribute("persons", persons); // request request.setAttribute("requestAttribute", "requestValue"); // session request.getSession().setAttribute("sessionAttribute", "sessionValue"); return "index"; } }
4）thymleaf基本功能使用示例
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>welcome</title> <!--引入资源--> <link rel="stylesheet" th:href="@{/css/index.css}"/> </head> <body> 属性: <div th:text="${properties}"></div> <hr/> 对象: <div th:text="${person.name}"></div> <hr/> if: <div th:if="${1 <= 2}">if true</div> <hr/> switch-case: <div th:switch="1"> <div th:case="1">case 1</div> <div th:case="2">case 1</div> <div th:case="3">case 1</div> <div th:case="4">case 1</div> </div> <hr/> 遍历: <div th:each="item, stat: ${persons}"> <span th:text="${item.name}"></span>: <span th:text="${stat.index}"></span> </div> <hr/> 跳转: <a th:href="@{http://www.baidu.com}">百度</a> <hr/> 图片: <img th:src="@{https://ss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=708140547,444241267&fm=27&gp=0.jpg}" alt="" style="display: block; 100px;height: 100px;"> <hr/> request取值: <div th:text="${requestAttribute}"></div> <hr/> session取值: <div th:text="${session.sessionAttribute}"></div> <hr/> </body> </html>
