具体报错：  
Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location \[/tmp/tomcat.8776548170270869740.8099/work/Tomcat/localhost/ROOT\] is not valid  
org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location

在运行springboot时 ，长时间运行后报错 the temporary uplaod location \*\*\* is not valid 查过资料后发现是centos对‘/temp’下文件自动清理的原因。 在springboot项目启动后 系统会在‘/temp’目录下创建几个目录 用于上传文件。因此清理过‘/temp’下文件后无法上传

解决方法： 1 重启服务；

2 改变临时文件的存储路径

@Configuration
        public class MultipartConfig{
            /**
            *文件临时上传路径
            */
          @Bean
          MultipartConfigElement multipartConfigElement() {
             MultipartConfigFactory factory = new MultipartConfigFactory();
             String location  = System.getProperty("user.dir") +"/data/tmp";
             File tmpFile   =new File (location);
               if(!tmpFile.exists()){
                tmpFile.mkdirs();
                 }
             Factory.setLocation(location);
             return factory.createMultipartConfig();
         }    
    }
