springboot 项目打包部署后设置上传文件访问的绝对路径

#静态资源对外暴露的访问路径
file.staticAccessPath=/upload/**
#文件上传目录（注意Linux和Windows上的目录结构不同）
#file.uploadFolder=/home/upload/
file.uploadFolder=d://upload/

@Configuration
public class UploadFileConfig {

    @Value("${file.uploadFolder}")
    private String uploadFolder;

    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setLocation(uploadFolder);
        //文件最大
        factory.setMaxFileSize("5MB");
        // 设置总上传数据总大小
        factory.setMaxRequestSize("10MB");
        return factory.createMultipartConfig();
    }
}

@Configuration
public class UploadFilePathConfig extends WebMvcConfigurerAdapter {

    @Value("${file.staticAccessPath}")
    private String staticAccessPath;
    @Value("${file.uploadFolder}")
    private String uploadFolder;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler(staticAccessPath).addResourceLocations("file:" + uploadFolder);
    }
}
