SprintBoot上传文件报错解决办法

问题描述

上传文件报错

java.io.IOException: The temporary upload location [/tmp/tomcat.4836362739890928439.2000/work/Tomcat/localhost/base] is not valid

问题分析

上传文件存放临时目录找不到致使错误

解决方案

参考https://blog.csdn.net/zdyueguanyun/article/details/79271300 初始化SpringBoot的Bean：MultipartConfigElement。指定上传临时目录路径

@Configuration
public class CommonConfiguration implements Serializable {
// Spring Boot上传须要指定一个临时文件目录,不然上传会报错
[@Bean](https://my.oschina.net/bean)
public MultipartConfigElement multipartConfigElement() {
		MultipartConfigFactory factory = new MultipartConfigFactory();
		String dirName = "springboot-upload-temp";
		String localTempFileDir = System.getProperty("user.home") + File.separator + dirName;
		File dir = new File(localTempFileDir);
		if (!dir.exists()) {
			dir.mkdirs();
		}
		factory.setLocation(localTempFileDir);
		return factory.createMultipartConfig();
	}
}
