springboot图片预览

在Spring Boot中实现图片预览可以通过配置静态资源的映射路径来实现。首先，在项目中创建一个配置类，例如`WebAppConfigurer`，并且让它实现`WebMvcConfigurer`接口。然后，在`addResourceHandlers`方法中，配置资源的虚拟路径和本地路径。比如，如果你想要访问`/upload/avatar/aaa.png`这个路径，程序会在`E:\\upload\\avatar\\`目录下查找`aaa.png`文件。最后，你可以使用这个地址在浏览器上进行图片预览。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
