springboot访问静态资源遇到的坑及解决

package com.example.demo.config;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Component
public class WebConfig implements WebMvcConfigurer {
/*
     * 添加静态资源文件，外部可以直接访问地址
     *
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }
}

spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/
static/,classpath:/public/ # Locations of static resources.

filterRuleMap.put("/static/**", "anon");

// 图片js文件等过滤配置
filterRuleMap.put("/css/**", "anon");
filterRuleMap.put("/js/**", "anon");
filterRuleMap.put("/img/**", "anon");
filterRuleMap.put("/pages/**", "anon");
// 首页过滤配置
filterRuleMap.put("/index.html", "anon");
filterRuleMap.put("/", "anon");

filterRuleMap.put("/myfiles/**", "anon");
// 首页过滤配置
filterRuleMap.put("/index.html", "anon");
filterRuleMap.put("/", "anon");
