一、引入场景
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
二、SpringBoot 自动配置原理中的 thymeleaf 的自动配置规则
只要我们把 HTM L页面放在 classpath:/templates/，thymeleaf 就能自动渲染；
@ConfigurationProperties(prefix = "spring.thymeleaf") public class ThymeleafProperties { private static final Charset DEFAULT_ENCODING = Charset.forName("UTF‐8"); private static final MimeType DEFAULT_CONTENT_TYPE = MimeType.valueOf("text/html"); //前缀 public static final String DEFAULT_PREFIX = "classpath:/templates/"; //后缀 public static final String DEFAULT_SUFFIX = ".html";
三、thymeleaf 语法
1、导入thymeleaf的名称空间（导入该名称空间后，就会有 thymeleaf 语法提示了）
<html lang="en" xmlns:th="http://www.thymeleaf.org">
2、helloworld
java 代码 @Controller public class HelloController { @RequestMapping("/success") public String success(Model model){ model.addAttribute("msg", "你好"); return "success"; } } html 代码 <!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <!--th:text 将div里面的文本内容设置为 ${msg}--> <div th:text="${msg}"></div> </body> </html>
