Question

我的Spring MVC应用程序包含一堆* .css，*。js和* .png文件，目前放在 src / main / java / resources / 中目录。我阅读了Spring Docs和一些关于如何使用ResourceHandlerRegistry类为我的模板加载这些文件的教程，但它并不适用于我。

我的WebConfig（扩展了WebMvcConfigurerAdapter）：

Answer 1

将文件从src / main / java / resources移动到src / main / resources 并删除＆＃34; / resources＆＃34;部分在spring配置中，例如

 <spring:url value="/css/style.css" var="css"/>

Maven会将文件放在classpass根目录下的resources目录中，而不是放在类路径根目录下的/ resources文件夹中。

JSP，导入css，js，图像
