1.引入依赖
<!--thymeleaf视图引擎-->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>html中要声明约束，这样就可以使用themelraf视图引擎了
<html lang="en" xmlns:th="http://www.thymeleaf.org">
2.样例
html:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<!--链接、引用需要用@{}，下面演示引入js和css-->
<!--<link rel="stylesheet" th:href="@{index.css}">-->
<!--<script type="text/javascript" th:src="@{index.js}"></script>-->
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
超链接
<div><a th:href="@{https://www.baidu.com/}">点击跳转百度！</a></div>
1.普通字符
<div th:text="${name}"></div>
2.JavaBean对象
<table bgcolor="#ffe4c4" border="1"><tr><td>介绍</td><td th:text="${user.name}"></td></tr><tr><td>年龄</td><td th:text="${user['age']}"></td></tr><tr><td>性别</td><td th:text="${user.getAge()}"></td></tr>
</table>
3.list集合
<table bgcolor="#ffe4c4" border="1"><tr th:each="item:${list}"><td th:text="${item.name}"></td><td th:text="${item.age}"></td><td th:text="${item.sex}"></td></tr>
</table>
4.map
<table bgcolor="#ffe4c4" border="1"><tr th:each="item:${map}"><td th:text="${item.key}"></td><td th:text="${item.value.sex}"></td></tr>
</table>
5.*使用
<div th:object="${user}"><p>Name: <span th:text="*{name}"></span>.</p><p>Age: <span th:text="*{age}"></span>.</p><p>sex: <span th:text="*{sex}"></span>.</p>
</div>
6.#直接从配置文件读取
<table bgcolor="#ffe4c4" border="1"><tr><td>name</td><td th:text="#{perspn.name}"></td></tr><tr><td>年龄</td><td th:text="#{person.age}"></td></tr><tr><td>性别</td><td th:text="#{person.sex}"></td></tr>
</table>
</body>
</html>User实体类：
package com.qcby.thymeleaf_demo01.pojo;
public class User {public String name;public Integer age;public Character sex;public User(String name, Integer age, Character sex) {this.name = name;this.age = age;this.sex = sex;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}public Character getSex() {return sex;}public void setSex(Character sex) {this.sex = sex;}}
Comtroller:
import com.qcby.thymeleaf_demo01.pojo.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;@Controller
public class urlController {@GetMapping("demo")//页面的url地址public String demo(Model model)//对应函数{User user1=new User("hhh",15,'女');User user2=new User("xxx",18,'女');User user3=new User("qqq",19,'女');List<User> list=new ArrayList<>();list.add(user1);list.add(user2);list.add(user3);Map<String ,User> map=new HashMap<>();map.put("hhh",user1);map.put("xxx",user2);map.put("qqq",user3);//数据添加到model中model.addAttribute("name","nihao");//普通字符串model.addAttribute("user",user1);//javabeanmodel.addAttribute("list",list);//listmodel.addAttribute("map",map);//Mapreturn "success";}
}
在直接读取properties文件的内容时：要springboot的配置文件声明路径
application.properties:
#直接读取配置文件
spring.messages.basename=templates/temptemp.properties文件：
perspn.name=超级飞侠
person.age=15
person.sex=男
)
 质数)
