Thymeleaf配置

Thymeleaf配置主要包括以下几个方面：

1. 引入Thymeleaf依赖：在项目的pom.xml文件中添加Thymeleaf相关的依赖，例如：

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

2. 配置Thymeleaf模板引擎：在Spring Boot的application.properties文件中配置Thymeleaf模板引擎相关属性，例如：

# 配置Thymeleaf模板引擎
spring.thymeleaf.mode=HTML
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.cache=false

3. 配置Thymeleaf视图解析器：在Spring Boot的配置类中配置Thymeleaf视图解析器，例如：

@Configuration
public class ThymeleafConfig {

    @Autowired
    private ApplicationContext applicationContext;

    @Bean
    public SpringResourceTemplateResolver templateResolver() {
        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setApplicationContext(applicationContext);
        templateResolver.setPrefix("classpath:/templates/");
        templateResolver.setSuffix(".html");
        templateResolver.setTemplateMode(TemplateMode.HTML);
        return templateResolver;
    }

    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        return templateEngine;
    }

    @Bean
    public ViewResolver viewResolver() {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        viewResolver.setCharacterEncoding("UTF-8");
        return viewResolver;
    }
}

其中，templateResolver方法配置了Thymeleaf模板引擎的相关属性；templateEngine方法配置了模板引擎，并将模板解析器注入到模板引擎中；viewResolver方法配置了Thymeleaf视图解析器，并将模板引擎注入到视图解析器中。通过这些配置，就可以使用Thymeleaf模板引擎了。
