使用Spring Boot的addResourceHandlers方法，可将请求路径映射到本地文件，实现本地资源的便捷访问。

package com.gmy.mybatis.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 WebMvcConfig implements WebMvcConfigurer {

    // 将请求路径映射到本地路径，例如，访问图片、视频和音频等
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // 图片
        registry.addResourceHandler("/test/picture/**").addResourceLocations("file:E:/pictures/");
        // 音频
        registry.addResourceHandler("/test/music/**").addResourceLocations("file:E:/musics/");
        // 视频
        registry.addResourceHandler("/test/video/**").addResourceLocations("file:E:/videos/");
    }
}
