Springboot在Controller类上添加RequestMapping后静态资源找不到

package com.xzj.config;

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

@Configuration
public class MyMvcConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //所有访问/admin/的都要去指定的位置下找资源
        registry.addResourceHandler("/admin/**").addResourceLocations("classpath:/static/");
    }

}
