SpringBoot上传文件 解决路径访问需要重启项目

1. 配置资源处理器

@Configuration
public class ResourceConfig {

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
		//上传目录
        String path = System.getProperty("user.dir") + "/src/main/resources/static/uploadFile/2021/10/15/";
       // addResourceHandler 添加路由过滤规则  addResourceLocations 添加本地映射目录
       registry.addResourceHandler("/uploadFile/**").addResourceLocations("file:"+path);
    }
}
