SpringBoot访问外部文件

1 新增配置类

package com.pibigstar.common.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import com.pibigstar.common.Constant;

@Configuration
public class WebConfig implements WebMvcConfigurer{

    /**
     * 访问外部文件配置，访问D盘下文件
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //配置server虚拟路径，handler为jsp中访问的目录，locations为files相对应的本地路径     
        registry.addResourceHandler("/files/**").addResourceLocations("file:///D:upload/");  
    }
}

2 访问

我们将test.jpg文件上传到D盘的upload文件夹后，那么在页面端访问则通过：localhost:8080/files/test.jpg
