官方文档入口：

1、首先需要引入thymeleaf的依赖（据官网文档，thymeleaf-spring3与thymeleaf-spring4用法基本一致）

        
     
      org.thymeleaf
         
     
      thymeleaf-spring4
         
     
      3.0.11.RELEASE
     
    

2、配置thymeleaf的模板解析器、模板引擎与视图解析器

官方文档以xml作为配置方法，因为不是很方便，此处使用java方式进行配置

import javax.servlet.ServletContext;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.web.context.ServletContextAware;import org.thymeleaf.spring4.SpringTemplateEngine;import org.thymeleaf.spring4.view.ThymeleafViewResolver;import org.thymeleaf.templateresolver.ServletContextTemplateResolver;@ComponentScan(basePackages="com.example.demo.controller")public class ServletConfig implements ServletContextAware {    private ServletContext servletContext;    @Override    public void setServletContext(ServletContext servletContext) {        this.servletContext = servletContext;    }    /* 加载thymeleaf模板 */    @Bean    public ServletContextTemplateResolver templateResolver() {        ServletContextTemplateResolver resolver = new ServletContextTemplateResolver(this.servletContext);        resolver.setPrefix("/WEB-INF/templates/");        resolver.setSuffix(".html");        resolver.setTemplateMode(TemplateMode.HTML);        resolver.setCharacterEncoding("UTF-8");        resolver.setCacheable(true);        return resolver;    }/* 模板引擎，渲染并返回结果 */    @Bean    public SpringTemplateEngine templateEngine() {        SpringTemplateEngine templateEngine = new SpringTemplateEngine();        templateEngine.setTemplateResolver(templateResolver());        templateEngine.setEnableSpringELCompiler(true);        return templateEngine;    }    /* 视图解析器 */    @Bean    public ThymeleafViewResolver viewResolver() {        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();        viewResolver.setTemplateEngine(templateEngine());        viewResolver.setCharacterEncoding("UTF-8");        return viewResolver;    }}

在配置模板解析器的时候，我选择的是实现ServletContextAware接口以获取ServletContext，并以此为参数创建ServletContextTemplateResolver。此处应该还可以用另一种方式进行配置：

public class WebConfig implements ApplicationContextAware{    private ApplicationContext applicationContext;    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException    {        this.applicationContext = applicationContext;    }    //加载 Thymeleaf 模板    @Bean    public SpringResourceTemplateResolver templateResolver()    {        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();        templateResolver.setApplicationContext(this.applicationContext);        templateResolver.setPrefix("/WEB-INF/templates/");        templateResolver.setSuffix(".html");        return templateResolver;    }}

3、测试：

@RequestMapping("/test")    public String test(Model model) throws IOException {        List
    
      userList = baseService.queryUsers();        model.addAttribute("userList", userList);        return "test";    }
    

4、此外，html页面常需要引入静态文件，为了饮用方便以及避免静态文件路径错误导致的异常，需要通过WebMvcConfigurer接口设置静态文件的根路径，避免路径错误导致的异常

@EnableWebMvcpublic class ServletConfig implements WebMvcConfigurer,ServletContextAware {    public void addResourceHandlers(ResourceHandlerRegistry registry) {        registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/templates/static/");    }}

注：需要在类上加入@EnableWebMvc注解表示启用java config，否则此方法不会生效。
