问题 文件上传有临时目录 这个目录在centos的情况下,会会被系统自动删除,导致文件上传出现问题
解决方式 指定文件上传的临时目录
配置如下

package com.***.core.config;

import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.multipart.MultipartResolver;

import javax.servlet.MultipartConfigElement;

    /**
     * @author imsjw
     * @Date Created in 13:47 2018/7/14
     */
    @Configuration
    public class FileUploadConfig {

        @Bean
        public MultipartConfigElement multipartConfigElement() {
            MultipartConfigFactory factory = new MultipartConfigFactory();
            factory.setLocation("/home/tmp");
            factory.setMaxFileSize(5*1024+"Mb");
            factory.setMaxRequestSize(5*1024+"Mb");
            return factory.createMultipartConfig();
        }

}
