解决方法

import com.qing.music.result.ResponseResultInterceptor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Autowired
    private ResponseResultInterceptor responseResultInterceptor;

    //统一返回值拦截
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(responseResultInterceptor).addPathPatterns("/**");
    }

    //解决  No mapping for GET /favicon.ico 访问静态资源图标
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
                .addResourceLocations("classpath:/static/")
                .addResourceLocations("classpath:/META-INF/resources/");
    }
