第一步:pom.xml加入依赖

　　　　　<!-- HTML templates-->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-thymeleaf</artifactId>

        </dependency>

如果出现错误 如下..

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'viewResolver' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration$Thymeleaf3Configuration$Thymeleaf3ViewResolverConfiguration': Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration$ThymeleafDefaultConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultTemplateResolver' defined in class path resource [org/springframework/boot/autoconfigure/thymeleaf/ThymeleafAutoConfiguration$Thymeleaf3Configuration$DefaultTemplateResolverConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver]: Factory method 'defaultTemplateResolver' threw exception; nested exception is java.lang.NoSuchMethodError: org.thymeleaf.templateresolver.TemplateResolver.checkNotInitialized()V
　　
我们应该修改 Properties配置

　　　　<properties>

        　　<thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>

        　　<thymeleaf-layout-dialect.version>2.1.1</thymeleaf-layout-dialect.version>

	</properties>

第二步: 修改yml文件

spring:

  thymeleaf:

      mode: HTML5

      encoding: utf-8

      content-type: text/html

      cache: false

第三步:修改Controller

    @GetMapping("/hello")

    String test(HttpServletRequest request) {

        //逻辑处理

        request.setAttribute("name", "java");

        return "/hello";

    }

第四步:修改html 放在resource/templates/hello.html

<!DOCTYPE html >

<html xmlns:th="http://www.thymeleaf.org">

<head>

    <title>Hello World!</title>

</head>

<body>

<span th:text="'Welcome to our application, ' + ${name} + '!'"></span>

</body>

</html>
