本文介绍如何在Spring Boot项目中集成Thymeleaf模板引擎，包括配置依赖、设置属性、创建Controller及Model，并展示如何在HTML页面中渲染数据。

前言

Spring-boot-starter-web集成了Tomcat以及Spring MVC，会自动配置相关东西，Thymeleaf是用的比较广泛的模板引擎

1.引入依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2.在一个名为application.propertiesde 的文件中配置Thymeleaf

server.port=8080
spring.thymeleaf.cache=false
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.check-template-location=true
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.mode=HTML5

3.文件结构

4.Controller

package com.dlp.Controller;

import com.dlp.model.Person;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by Administrator on 2017/9/6.
 */
@Controller
public class HelloController {

    @RequestMapping(value = "/index")
    public String index(Model  model)
    {
        Person single = new Person("hyj",21);
        List<Person> people = new ArrayList<Person>();
        Person p1 = new Person("dlp",21);
        Person p2 = new Person("tq",21);
        Person p3 = new Person("mk",21);
        people.add(p1);
        people.add(p2);
        people.add(p3);
        model.addAttribute("singlePerson",single);
        model.addAttribute("people",people);
        return "index";
    }
    }

这里使用@Controller而不用@RESTController是因为这里返回一个页面而不是一个值，如果只是使用@RestController注解Controller，则Controller中的方法无法返回jsp页面，配置的视图解析器InternalResourceViewResolver不起作用，返回的内容就是Return 里的内容。

5.Model类

package com.dlp.model;

/**
 * Created by Administrator on 2017/9/6.
 */
public class Person {
    private String name;
    private Integer age;
    public Person()  {
        super();
    }
    public Person(String name,Integer gae) {
        super();
        this.name=name;
        this.age=gae;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name=name;
    }
    public Integer getAge() {
        return age;
    }

    public Integer setAge(Integer age) {
        return age;
    }
}

6.index页面

<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" >
<head>
    <meta content="text/html;charset=UTF-8"/>

</head>
<body>
<div class="panel panel-primary">
   <div class="panel-heading">
       <h3 class="panel-title">访问model</h3>
   </div>
    <div class="panel-body">
        <span th:text="${singlePerson.name}"></span>
    </div>
</div>
<div th:if="${not #lists.isEmpty(people)}">
    <div class="panel panel-primary">
        <div class="panel-heading">
            <h3 class="panel-title">列表</h3>
        </div>
        <div class="panel-body">
            <ul class="list-group">
                <li class="list-group-item" th:each="person : ${people}">
                    <span th:text="${person.name}"></span>
                    <span th:text="${person.age}"></span>
                    <button class="btn" th:onlick="'getName(\''+${person.name}+'\');'">获得名字</button>
                </li>
            </ul>
        </div>
    </div>
</div>
<script th:src="@{/jquery/jquery-3.2.1.min.js}"></script>
<script th:src="@{/bootstrap/js/bootstrap.min.js}"></script>
<script th:inline="javascript">
    var single = [[${singlePerson}]];
    console.log(single.name+"/"+single.age);
    function getName(name) {
        console.log(name);
    }
</script>
</body>
</html>
