spring-boot上传文件,临时文件地址无效

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location [/tmp/tomcat.2737591724424319502.8062/work/Tomcat/localhost/ROOT] is not valid
临时文件地址无效

解决办法： 

1.重启服务。

2.增加启动参数-Djava.io.tmpdir=自定义目录

3.注入配置:

    @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();
    }
