[SpringBoot2]Thymeleaf

引入starter

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

自动配置好了thymeleaf

@Configuration(proxyBeanMethods = false)
@EnableConfigurationProperties(ThymeleafProperties.class)
@ConditionalOnClass({ TemplateMode.class, SpringTemplateEngine.class })
@AutoConfigureAfter({ WebMvcAutoConfiguration.class, WebFluxAutoConfiguration.class })
public class ThymeleafAutoConfiguration { }

自动配好的策略
● 1、所有thymeleaf的配置值都在 ThymeleafProperties
● 2、配置好了 SpringTemplateEngine
● 3、配好了 ThymeleafViewResolver
● 4、我们只需要直接开发页面

	public static final String DEFAULT_PREFIX = "classpath:/templates/";public static final String DEFAULT_SUFFIX = ".html";  //xxx.html

名称空间

xmlns:th="http://www.thymeleaf.org"

测试：

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body>
<h1 th:text="${msg}">哈哈</h1>
<h2><a href="www.atguigu.com" th:href="${link}">去百度</a>  <br/><a href="www.atguigu.com" th:href="@{link}">去百度2</a>
</h2>
</body>
</html>

@Controller
public class ViewTestController {@GetMapping("/atguigu")public String atguigu(Model model){//model中的数据会被放在请求域中，相当于request.setAttribute("a",aa)model.addAttribute("msg","hello,world");model.addAttribute("link","http://www.baidu.com");return "success";}}
