**这是因为springboot项目自动删除了临时文件**

## 解决方案： ##

1.  重启项目（生产不建议）
2.  在propertites文件中配置： `spring.http.multipart.location=` 临时文件路径
3.  配置临时文件位置

@Configuration
    public class MultipartConfig { 
    
        @Bean
        MultipartConfigElement multipartConfigElement() { 
            MultipartConfigFactory factory = new MultipartConfigFactory();
            factory.setLocation("/");  //这个路径可以随便写
            return factory.createMultipartConfig();
        }
    }

**以上这三种解决方式均可，依情况而定**
