例如要访问的本地路径是D盘下的PersonalHomePage目录的某个图片

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

/**
 * 资源映射路径
 */
@Configuration
public class MyWebAppConfigurer implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/PersonalHomePage/**").addResourceLocations("file:D:/PersonalHomePage/");
    }
}
