spring-boot-autoconfigure-1.5.1.RELEASE.jar!/org/springframework/boot/autoconfigure/web
上述jar的web包下，編寫了自動配置Web項的邏輯
下面列舉常用的幾個類
ServerPropertiesAutoConfiguration和ServerProperties，自動配置內嵌Servlet容器
HttpEncodingAutoConfiguration和HttpEncodingProperties，自動配置http編碼，默認utf-8
MultipartAutoConfiguration和MultipartProperties，自動配置文件上傳
JacksonHttpMessageConvertersConfiguration，自動配置MappingJackson2HttpMessageConverterConfiguration與MappingJackson2XmlHttpMessageConverterConfiguration
WebMvcAutoConfiguration和WebMvcProperties，自動配置Spring MVC
Spring Boot推薦使用Thymeleaf作為模板引擎，其提供了完美的Spring MVC支持、
內嵌Tomcat、Jetty無法執行jar形式的jsp；Undertow不支持JSP
- Thymeleaf頁面基本樣式
<!DOCTYPE html><html xmlns:th="http://www.thymeleaf.org"><head><meta charset="UTF-8"><title>首頁</title><link th:href="@{bootstrap/css/bootstrap.min.css}" rel="stylesheet"/><link th:href="@{bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet"/><script th:src="@{jquery-1.10.2.min.js}" type="text/javascript"></script><script th:src="@{bootstrap/js/bootstrap.min.js}"></script></head><body>Hello World</body></html>
xmlns:th="http://www.thymeleaf.org" 引入Thymeleaf命名空間，將靜態頁面轉化成動態頁面。需要動態處理的元素將使用 th: 作為前綴
@{bootstrap/js/bootstrap.min.js} 引入Web靜態資源
- 訪問model中元素屬性
<div class="panel panel-primary"><div class="panel-heading"><h3 class="panel-title">訪問model</h3></div><div class="panel-body"><span th:text="${singlePerson.name}"></span></div></div>
訪問model中singlePerson的name屬性。這里需要為text屬性添加th:前綴
- 迭代元素
- <ul class="list-group">
<li class="list-group-item" th:each="person:${people}"><span th:text="${person.name}"></span><span th:text="${person.age}"></span><button class="btn" th:onclick="'getName(\'' + ${person.name} + '\');'">獲得名字</button></li></ul>
th:each做循環迭代person作為迭代元素，${person}訪問model中元素
- 空判斷
<div th:if="${not #lists.isEmpty(people)}"></div>
判斷person是否為空，Thymeleaf支持>、<、>=、<=、==、!=、SpEL表達式
- JavaScript中訪問model中元素
<script th:inline="javascript">var single = [[${singlePerson}]];console.log(single.name+"/"+single.age)function getName(name){console.log(name);}</script>
使用[[${modelName}]]獲取model中的元素值
- Thymeleaf與Spring MVC集成
pom
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>
引入默認靜態文件
靜態文件包括 腳本、樣式、圖片，默認在src/main/resources/static下
編寫Thymeleaf模板
默認位置在 templates
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>測試頁面</title>
<link th:href="@{bootstrap/css/bootstrap.min.css}" rel="stylesheet"/>
<link th:href="@{bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet"/>
<script th:src="@{jquery-1.10.2.min.js}" type="text/javascript"></script>
<script th:src="@{bootstrap/js/bootstrap.min.js}"></script>
</head>
<body>
Hello World<br/>
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">訪問model</h3>
</div>
<div class="panel-body">
<!--/*@thymesVar id="singlePerson" type=""*/-->
<span th:text="${singlePerson.name}"></span>
</div>
</div>
<div th:if="${not #lists.isEmpty(people)}">
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">列表</h3>
</div>
<div class="panel-body">
<ul class="list-group">
<li class="list-group-item" th:each="person:${people}">
<span th:text="${person.name}"></span>
<span th:text="${person.age}"></span>
<button class="btn" th:onclick="'getName(\'' + ${person.name} + '\');'">獲得名字</button>
</li>
</ul>
</div>
</div>
</div>
<script th:inline="javascript">
var single = [[${singlePerson}]];
console.log(single.name + "/" + single.age);
function getName(name) {
console.log(name);
}
</script>
</body>
