}

所有 /webjars/** ，都去 classpath:/META-INF/resources/webjars/ 找資源；

?webjars：以jar包的方式引入靜態(tài)資源；?

https://www.webjars.org/ 找到需要引入的資源文件 寫到pom中：?

<dependency>

   <groupId>org.webjars</groupId>

   <artifactId>jquery</artifactId>

   <version>3.3.1</version>

</dependency>

?自定義的靜態(tài)資源存放：ResourceProperties?

"/**" 訪問當前項目的任何資源，都去（靜態(tài)資源的文件夾）找；

?

{

"classpath:/META-INF/resources/", "classpath:/resources/",

"classpath:/static/", "classpath:/public/" };

"/"：當前項目的根路徑

自定義圖標

命名為favicon.ico，放在靜態(tài)文件夾下即可！

自定義靜態(tài)文件存放路徑：spring.resources.static-locations=classpath:/qmk
