springBoot 怎么实现内置tomcat配置虚拟目录

一、springboot 1.x配置

@Configurationpublic
public class MyWebMvcConfigurerAdapter extends WebMvcConfigurerAdapter {
      @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {        /**
             * 资源映射路径
             * addResourceHandler：访问映射路径
             * addResourceLocations：资源绝对路径
             */
            registry.addResourceHandler("/image/**").addResourceLocations("file:D:/temp/image/");
        }
    }

记得一定得加上file。file后加上本地磁盘地址文件夹

二、springboot 2.x配置

@Configurationpublic class MyWebAppConfigurer implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/image/**").addResourceLocations("file:D:/temp-rainy/");
    }
}

然后访问 localhost：8080/image/ 加上图片名。。就可以访问到了。。
