1. @{}: Hyperlink expression in thymeleaf
The examples are as follows:
<a th:href="@{/user/login}"></a>
<a th:src="@{/user/login}"/>2. #{}: Message expression or resource expression in thymeleaf
Generally used with th:text a little more, the value taken out by #{} replaces the value in the label, and the value corresponding to #{key}. If there is already a value in the middle of the label, the value retrieved by #{} will overwrite the value in the label
The examples are as follows:
<div th:text="#{user}"> </div>3. ${}: Variable expression, used to access the variables of the container context, such as domain variables: request domain, session domain
Think about it carefully, a bit of the meaning of the ${} function in jstl
The examples are as follows:
// 后端代码
session.setAttribute("list",list);
<--取域中的值-->
<div>[[${list}]]</div>4. *{}: The selection expression is the selected object, not the mapping of the entire environment
If there is no object, it is basically the same as the variable expression ${}
<p>Name: <span th: text=" *{firstName}" >Sebastian</span>. </p>
<p>Surname: <span th: text=" *{lastName}" >Pepper</span>. </p>
