Springboot如何加载静态图片

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class ShowImage extends WebMvcConfigurerAdapter {
 
    /**
     * 注入图片存放路径
     */
    @Value("${upload.path.prefix}")
    private String prefix;
    @Value("${upload.path.res}")
    private String uploadPath;
 
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
           //注：使用此种方法进行路径配置时，“file:D:/OTA/” 为正确路径地址 “file:D:/OTA”为错误路径地址，需以反斜杠结尾才可正确加载
        registry.addResourceHandler("/images/**").addResourceLocations("file:" + prefix + "/");
        super.addResourceHandlers(registry);
    }
}

upload:
  path:
    prefix: d:/app/share/data
    res: /upload/resource/
