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

以上这篇SpringBoot使用Thymeleaf自定义标签的实例代码就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
