此篇文章內(nèi)容僅限于 描述springboot與 thy 自定義標(biāo)簽的說(shuō)明，所以你在看之前，請(qǐng)先會(huì)使用springboot和thymeleaf！！
之前寫過(guò)一篇是springMVC與thymeleaf 的自定義標(biāo)簽（屬于自定義方言的屬性一塊，類似thy的th:if和th:text等）文章，如果你想了解，以下是地址：
點(diǎn)擊>>Thymeleaf3.0自定義標(biāo)簽屬性
這篇例子可以實(shí)現(xiàn)你的分頁(yè)標(biāo)簽實(shí)現(xiàn)等功能，不會(huì)講一堆的廢話和底層的原理（自行百度），屬于快速上手教程，請(qǐng)認(rèn)真看以下內(nèi)容！
PS: 請(qǐng)?jiān)试S我將thymeleaf簡(jiǎn)稱thy，springboot簡(jiǎn)稱sb
依然直奔主題，sb本身是自帶thy的，而且使用方式也很簡(jiǎn)單，直接配置application.properties 這個(gè)文件就可以了，當(dāng)然你不配也是可以的。但是，需要配置自定義方言的話，就需要自己把配置重新寫出來(lái)，看下面代碼：
說(shuō)明：RiskDialect是我自己的自定義標(biāo)簽，而且從這個(gè)配置可以簡(jiǎn)單看出，spring視圖的配置通過(guò)注解的方式將thymeleaf配置進(jìn)去了

@Configurationpublic 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>(); //自定義方言 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; }} |
接下來(lái)看RiskDialect實(shí)現(xiàn)：
說(shuō)明：SanstitvEncryptProcessor這個(gè)類是 thymeleaf處理器，用來(lái)處理定義方言邏輯的

html使用方式：
risk:sanstitv 是我自定義用的標(biāo)簽
