此篇文章內容僅限于 描述springboot與 thy 自定義標簽的說明，所以你在看之前，請先會使用springboot和thymeleaf！！
之前寫過一篇是springMVC與thymeleaf 的自定義標簽（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：
這篇例子可以實現你的分頁標簽實現等功能，不會講一堆的廢話和底層的原理（自行百度），屬于快速上手教程，請認真看以下內容！
PS: 請允許我將thymeleaf簡稱thy，springboot簡稱sb
依然直奔主題，sb本身是自帶thy的，而且使用方式也很簡單，直接配置application.properties 這個文件就可以了，當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，看下面代碼：
說明：RiskDialect是我自己的自定義標簽，而且從這個配置可以簡單看出，spring視圖的配置通過注解的方式將thymeleaf配置進去了

接下來看RiskDialect實現：
說明：SanstitvEncryptProcessor這個類是 thymeleaf處理器，用來處理定義方言邏輯的

html使用方式：
risk:sanstitv 是我自定義用的標簽

以上這篇SpringBoot使用Thymeleaf自定義標簽的實例代碼就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持服務器之家。
