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

参考链接：重点设置临时目录的绝对路径 System.getProperty(“user.dir”) + “/data/tmp”;

解决办法： 启动类中加入配置临时文件目录

@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();
}

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();
factory.setLocation("/app/pttms/tmp");
return factory.createMultipartConfig();
}
