此篇文章内容仅限于 描述springboot与 thy 自定义标签的说明，所以你在看之前，请先会使用springboot和thymeleaf！！
之前写过一篇是springMVC与thymeleaf 的自定义标签（属于自定义方言的属性一块，类似thy的th:if和th:text等）文章，如果你想了解，以下是地址：
这篇例子可以实现你的分页标签实现等功能，不会讲一堆的废话和底层的原理（自行百度），属于快速上手教程，请认真看以下内容！
PS: 请允许我将thymeleaf简称thy，springboot简称sb
依然直奔主题，sb本身是自带thy的，而且使用方式也很简单，直接配置application.properties 这个文件就可以了，当然你不配也是可以的。但是，需要配置自定义方言的话，就需要自己把配置重新写出来，看下面代码：
说明：RiskDialect是我自己的自定义标签，而且从这个配置可以简单看出，spring视图的配置通过注解的方式将thymeleaf配置进去了

@Configuration
public class TemplateEngineConfig{
@Bean
public ContentNegotiatingViewResolver getViewResolver(){
ServletContextTemplateResolver templateResolver=new ServletContextTemplateResolver();
templateResolver.setPrefix("/WEB-INF/views/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode("HTML5");
templateResolver.setCacheable(false);
templateResolver.setCharacterEncoding("UTF-8");
Set<IDialect> additionalDialects=new LinkedHashSet<IDialect>();
//自定义方言
additionalDialects.add(new RiskDialect());
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setAdditionalDialects(additionalDialects);
templateEngine.setTemplateResolver(templateResolver);
ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();
thymeleafViewResolver.setTemplateEngine(templateEngine);
thymeleafViewResolver.setCharacterEncoding("UTF-8");
thymeleafViewResolver.setOrder(1);
List<ViewResolver> viewResolvers= new ArrayList<>();
viewResolvers.add(thymeleafViewResolver);
ContentNegotiatingViewResolver viewResolver = new ContentNegotiatingViewResolver();
viewResolver.setViewResolvers(viewResolvers);
return viewResolver;
}
}

接下来看RiskDialect实现：
说明：SanstitvEncryptProcessor这个类是 thymeleaf处理器，用来处理定义方言逻辑的

html使用方式：
risk:sanstitv 是我自定义用的标签
