SpringBoot2 配置thymeleaf

作者: kason_zhang | 来源:发表于2018-11-03 12:27 被阅读1次

SpringBoot中开发web时使用thymeleaf作为前端

1 配置

properties文件修改为:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <!--引入themeleaf-->
        <thymeleaf.version> 3.0.2.RELEASE </thymeleaf.version>
        <thymeleaf-layout-dialect.version> 2.1.1 </thymeleaf-layout-dialect.version>
    </properties>

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <!-- Thymeleaf方言支持SpringSecurity 依赖-->

然后reources中的application.properties文件加入thymeleaf的配置:

# thymeleaf
spring.thymeleaf.cache=false
spring.thymeleaf.mode=HTML5

2 提供html

在templates里面编写一个index.html文件

3 编写一个Controller, 跳转到index.html

package com.kason.kasonpro.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by zhangkai12 on 2018/6/19.
 */
@Controller
public class HomeController {

    @GetMapping("/")
    public String index() {
        return "index";
    }
    @RequestMapping("/test")
    public String test(){
        return "index";
    }
}

启动SpringBoot, 输入localhost:8080 发现可以正常加载html页面

4 使用thymeleaf模块传参

html页面的修改:

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
Hello

<h2 th:text="${name}"></h2>
</body>
</html>

相对于上个, 此处的更改有两处:
1, xmlns:th="http://www.thymeleaf.org (加入这个才能使用themeleaf的语法)
2, <h2 th:text="${name}"></h2> (具体语法使用)

controller处的更改:

 @RequestMapping("/test")
    public String test(Model model){
        model.addAttribute("name","test-Model-submit-param");
        return "index";
    }

方法中传入了Model参数, 此Model类会封装属性, 传给html页面, 此处是增加了一个name属性,其值是test-Model-submit-param

更改上面两处之后, 运行, 输入http://localhost:8080/test, 显示如下:

5 thymeleaf 模板使用

官网地址:https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html

if语句, 判断是否为空 th:if

<div th:if="${singleuser} != null ">
    <h3 th:text="${singleuser.name}">333</h3>
</div>

循环
html修改:

<div th:if="not ${#lists.isEmpty(list)}">
    <div th:each="user: ${list}">
        <p th:text="'名字: ' + ${user.name}"></p>
        <p th:text="'年龄: ' + ${user.age}"></p>
    </div>
</div>

controller代码修改:

@GetMapping("userList")
    public String userList(Model model) {
        List<User> userList = new ArrayList<>();
        userList.add(new User("smith", 18));
        userList.add(new User("kate", 20));
        userList.add(new User("kason", 26));
        model.addAttribute("list", userList);
        return "index";
    }

结果:
