1.静态资源位置
resources>static:>public
在templates目录下只能通过controller跳转==(需要thymeleaf模板引擎的支持)==
2.springboot自带彩蛋
(1).网页图标
<img src="C:\Users\肖云龙\AppData\Roaming\Typora\typora-user-images\image-20220420165323092.png" alt="image-20220420165323092" style="zoom: 50%;" />
(2).banner
3.Thymeleaf
thymeleaf视图解析器中redirect/forward好像没了
(1).相关的html文件中头部
xmlns:th="http://www.thymeleaf.org"
<!--所有的html元素都可以被thymeleaf替换接管： th:元素名-->
相关语法
(2).我们可以使用任意的 th:attr 来替换Html中原生属性的值!
(3).我们能写哪些表达式呢？
Simple expressions:（表达式语法）
Variable Expressions: ${...}：获取变量值；OGNL；
1）、获取对象的属性、调用方法
2）、使用内置的基本对象：#18
#ctx : the context object.
#vars: the context variables.
#locale : the context locale.
#request : (only in Web Contexts) the HttpServletRequest object.
#response : (only in Web Contexts) the HttpServletResponse object.
#session : (only in Web Contexts) the HttpSession object.
#servletContext : (only in Web Contexts) the ServletContext object.
3）、内置的一些工具对象：
#execInfo : information about the template being processed.
#uris : methods for escaping parts of URLs/URIs
#conversions : methods for executing the configured conversion service (if any).
#dates : methods for java.util.Date objects: formatting, component extraction, etc.
#calendars : analogous to #dates , but for java.util.Calendar objects.
#numbers : methods for formatting numeric objects.
#strings : methods for String objects: contains, startsWith, prepending/appending, etc.
#objects : methods for objects in general.
#bools : methods for boolean evaluation.
#arrays : methods for arrays.
#lists : methods for lists.
#sets : methods for sets.
#maps : methods for maps.
#aggregates : methods for creating aggregates on arrays or collections.
