Spring Boot 使用 Thymeleaf模板

Thymeleaf

Thymeleaf是一个XML/XHTML/HTML5模板引擎,可用于Web与非Web环境中的应用开发。它是一个开源的Java库,基于Apache License 2.0许可,由Daniel Fernández创建,该作者还是Java加密库Jasypt的作者。

首先在pom.xml文件中增加对Thymeleaf的依赖

<!-- 增加Thymeleaf的模板使用 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>


增加application.yml配置

spring:
thymeleaf:
# Enable template caching.
cache: true
# Check that the templates location exists.
check-template-location: true
# Content-Type value.
content-type: text/html
# Enable MVC Thymeleaf view resolution.
enabled: true
# Template encoding.
encoding: UTF-8
# Comma-separated list of view names that should be excluded from resolution.
#excluded-view-names:
# Template mode to be applied to templates. See also StandardTemplateModeHandlers.
mode: HTML5
# Prefix that gets prepended to view names when building a URL.
prefix: classpath:/templates/thymeleaf/
# Suffix that gets appended to view names when building a URL.
suffix: .html
# Order of the template resolver in the chain.
#template-resolver-order:
# Comma-separated list of view names that can be resolved.
#view-names:


配置prefix时一定要注意 classpath:/templates/thymeleaf/ 最后的这个/一定要加, 否则解析的时候会模板不存在,解析不了的情况



编写Controller.java文件

package com.imooc.controller;

import com.imooc.properties.GirlProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
* 因为使用了Thymeleaf模板,所以不能使用RestController
* Created by ZhouBJ on 2017/9/29.
*/
@Controller
public class HelloController {

/**
* 使用Thymeleaf模板
* @param modelMap
* @return
*/
@RequestMapping(value="/hello/index", method = RequestMethod.GET)
public String helloIndex( ModelMap modelMap){
// 加入一个属性,用来在模板中读取 - 此处的值将会覆盖模板页面本身已经存在的值
modelMap.addAttribute( "title", "标题-测试页面" );
modelMap.addAttribute( "host", "demo.baomidou.com:8080" );
// return模板文件的名称,对应src/main/resources/templates/index.html
return "index";
}
}


修改index.html

<!DOCTYPE html>
<html xmlns:th="http://www.w3.org/1999/xhtml">
<head lang="en">
<meta charset="UTF-8" />
<title th:text="${title}">Hello,测试页</title>
</head>
<body>
<h1 th:text="${host}">Hello World</h1>
</body>
</html>
