本文介绍如何在Spring Boot项目中集成Thymeleaf模板引擎，包括添加依赖、配置属性、创建控制器方法及视图展示等步骤，并解决常见错误。

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>
