Springboot 之引入Thymeleaf

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"/>
    <meta name="viewport" content="width=device-width,initial-scale=1"/>
    <link th:href="@{/bootstrap/css/bootstrap.min.css}" rel="stylesheet"/>
    <link th:href="@{/bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet"/>
</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>

xmlns:th="http://www.thymeleaf.org"命名空间，将镜头转化为动态的视图，需要进行动态处理的元素使用“th:”前缀；两个link引入bootstrap框架，通过@{}引入web静态资源（括号里面是资源路径）访问model中的数据通过${}访问，案例

7.运行
