springboot项目小总结
使用模板引擎 thyemlef 可以直接将 html文件进行导入
loginhtml文件 html中常用的表达式
<link href="asserts/css/signin.css" th:href="@{/asserts/css/signin.css}" rel="stylesheet">
<form class="form-signin" action="dashboard.html" th:action="@{/user/login}" method="post">
<img class="mb-4" src="asserts/img/bootstrap-solid.svg" th:src="@{asserts/img/bootstrap-solid.svg}" alt="" width="72" height="72">
<h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">Please sign in</h1>
<p style="color: red" th:text="${msg}" th:if="${not #strings.isEmpty(msg)}"></p>
<input type="password" name="password" class="form-control" th:placeholder="#{login.password}" placeholder="Password" required="">
<a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>
参数直接写在（）中
<input type="checkbox" value="remember-me"/> [[#{login.remember}]] 行内表达式

又因为html中页面中会有很多重复的代码此时可以抽取出来常用的操作有
可以将抽取的代码放在一个文件夹中
<!--引入上边栏目-->
<!--引入topbar-->
<div th:replace="commons/bar::topbar"></div>
<!--引入sidebar-->
<div th:replace="commons/bar::#sidebar(activeUri='main.html')"></div>
在哪删的就在哪引入
