    // 路径映射配置
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {

        // 将网页地址栏中的 /order/**  映射到  工程类路径下的 /order/ 中，以访问resources/order中的资源
        registry.addResourceHandler("/order/**").addResourceLocations("classpath:/order/");
        // 磁盘目录
        String path = "E:\\xxx\\xxx\\";   
        // 将网页地址栏中的 /image/**  映射到  磁盘的某个目录下，以访问磁盘资源 
        registry.addResourceHandler("/image/**").addResourceLocations("file:" + path);
     
    }
