SpringBoot访问图片等静态资源

重写addResourceHandlers()后，\upload\ 下的静态资源可以访问了

package com.sd.xm003.config;
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 PathConfig extends WebMvcConfigurerAdapter{
 
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/upload/**").addResourceLocations("classpath:/upload/");
        super.addResourceHandlers(registry);
    }
 
}
