1.引入jar包

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
</dependency>

2.建立配置類

package com.common.config;

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.WebMvcConfigurer;

/**
 * @BelongsProject: demo
 * @Author: DanBrown
 * @CreateTime: 2020-03-28 14:33
 * @description: TODO
 */
@Configuration
public class WebConfig implements WebMvcConfigurer {
  @Value("${upload.path}")
  private String uploadPath;

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    // /home/file/**為前端URL訪問路徑 後面 file:xxxx為本地磁碟對映
    registry.addResourceHandler("/home/file/**").addResourceLocations("file:C:" + uploadPath);
  }
}

3. 訪問

http://localhost:8080/home/file/820123.png
