SpringBoot整合Hutool实现文件上传的使用示例

前言

我相信我们在日常开发中，难免会遇到对各种媒体文件的操作，由于业务需求的不同对文件操作的代码实现也大不相同

数据库设计

yaml配置我们的上传路径

# 文件上传配置
files:
  ip: localhost
  upload:
    location: file:F:/项目/SpringBoot+vue/tg-admin/server/files/
    path: /img/**

上传

maven配置

配置静态资源映射

    @Value("${files.upload.path}")
    private String filePath;
    @Value("${files.upload.location}")
    private String fileLocation;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //注册配置类，使用addResourceHandlers方法，将本地路径fileLocation映射到filePath路由上。
        registry.addResourceHandler(filePath).addResourceLocations(fileLocation);
        WebMvcConfigurer.super.addResourceHandlers(registry);
    }
