本文系云原生应用最佳实践杭州站活动演讲稿整理。杭州站活动邀请了 Apache APISIX 项目 VP 温铭、又拍云平台开发部高级工程师莫红波、蚂蚁金服技术专家王发康、有赞中间件开发工程师张超,分享云原生落地应用的经. Tips:(1) @RequestPart('picture') : 当注册表单提交的时候,p icture 属性将会给定一个 byte 数组,这个数组中包含了请求中对应 part 的数据(通过 @RequestPart 指定)。 如果用户提交表单的时候没有选择文件,那么这个数组会是空(而不是 null )。 所以说我们甚至可以用byte数组接收Multipart请求而不用.
There was no test server using the test environment for some time.
Then I want to use the test environment yesterday to upload the files. There was no problem before, but it can’t be used suddenly today. Open the log file and it is found that the error is reported as the above error. Is missing file.
But generally no one cleans up the files on the server.??????
Later, according to the multi-party search, the reason was found. It turns out that the files in TMP directory that have not been used in 10 days will be automatically cleared under Linux. When springboot is started, a Tomcat. * file directory will be generated under / tmp directory for the file stream operation of “Java. Io. TMPDIR”. Because no one operates during the holiday, the Linux system will automatically delete the temporary files, resulting in the upload error
