若是你並不瞭解SpringBoot的靜態頁面,請看個人Thymeleaf第一篇:html
這是 Thymeleaf(一) 的連接 : aaatao66.github.io/2019/05/26/…java
使用本身的圖標:git
在靜態資源文件夾放一個 favicon.ico 的圖標,springboot底層會自動調用這個爲咱們的圖標github
我找了個小叮噹的圖標web
效果:spring
在你的 yml/properties下添加:express
spring.resources.static-locations=classpath:/hello/,classpath:/carson/

定義以後,原來默認的就不能夠使用了springboot
SpringBoot推薦使用thymeleaf,由於語法簡單,功能強大, 不推薦使用jsp,默認也不支持jspbash
<!-- 引入 thymeleaf 模板引擎-->

新版本的Spring Boot會自動設置好版本,若是你是1.x的Spring Boot,可能要本身更改版本了session
源碼:
@ConfigurationProperties(
prefix = "spring.thymeleaf"
)
public class ThymeleafProperties {
private static final Charset DEFAULT_ENCODING;
public static final String DEFAULT_PREFIX = "classpath:/templates/";
public static final String DEFAULT_SUFFIX = ".html";
private boolean checkTemplate = true;
private boolean checkTemplateLocation = true;
// 下面是先後綴,也就是說只要放在 prefix 目錄下,就能夠被渲染了
private String prefix = "classpath:/templates/";
private String suffix = ".html";

小總結:
<div th:text="${hello}"></div>
<div th:utext="${hello}"></div>
複製代碼
th:text : 轉義特殊字符,因此頁面顯示 <h1>你好</h1>
th:utext: 不轉義特殊字符, 頁面直接顯示 h1標籤 大標題 你好
th:each: 寫在 h4 標籤上,每次遍歷都會產生一個新的 h4標籤:
zhangsan lisi wangwu
