idea springboot 添加访问图片的虚拟路径

步骤：

1.继承WebMvcConfigurerAdapter

2.重写addResourceHandlers方法

3.加入要配置的虚拟路径registry.addResourceHandler(“/upload/image/**”).addResourceLocations(“file:G:/upload/image/”);

Demo如下：

/**
  * 在spring boot中加入相应配置的扫描
  */
@Configuration
public class ApplicationConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        /*
        * 说明：增加虚拟路径(经过本人测试：在此处配置的虚拟路径，用springboot内置的tomcat时有效，
        * 用外部的tomcat也有效;所以用到外部的tomcat时不需在tomcat/config下的相应文件配置虚拟路径了,阿里云linux也没问题)
        */
        registry.addResourceHandler("/upload/image/**").addResourceLocations("file:G:/upload/image/");
        registry.addResourceHandler("/upload/video/**").addResourceLocations("file:G:/upload/video/");

        //阿里云(映射路径去除盘符)
        //registry.addResourceHandler("/ueditor/image/**").addResourceLocations("/upload/image/");
        //registry.addResourceHandler("/ueditor/video/**").addResourceLocations("/upload/video/");
        super.addResourceHandlers(registry);
    }
}
