新建一个类

• 继承WebMvcConfigurationSupport，对静态资源目录说明

package com.mobai.color.controller;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }
}

引用方式(使用了thymeleaf模板引擎)

<link rel="stylesheet" type="text/css" th:href="@{/static/css/bootstrap.min.css}"/>
<link rel="stylesheet" type="text/css" th:href="@{/static/font-awesome/css/font-awesome.min.css}"/>
<link rel="stylesheet" type="text/css" th:href="@{/static/css/style.css}"/>
