Which Approach Is Best for Processing a huge CSV file?
I searched the internet on how to processing huge csv file via Java
I found out
a. Spring Batch
b. Apache Nifi
c. Apache Mina
d. Kafka
Basically i want to insert millions of records after validation into DB.
Which one is preferable as finally the data is to be committed to the DB very quickly or fast...
Note: Hundreds or Thousands of users will do the similar operation at the same time and system should not crash
Thanks
Five Cases Of Encoding - Which One is Best Approach
I have a password which has plus value in the front and fails or missed out when it is sends as a request parameter. On reading/searching internet i observed we can solve the problem via the following
a. encode in front-end - (ex: https://stackoverflow.com/questions/53546691/preserving-plus-sign-in-urlencoded-http-post-request)
b. encode in back-end - (ex: extends ClientHttpRequestInterceptor and add functionality)
c. convert the password to base64url in front-end and pass and do the decode in the back-end
d. send the password in request body instead of request parameter
e. send the hash value instead of actual value as hash will not have any plus or special characters
Thanks
Text Over Image with Java Web Application
https://www.baeldung.com/java-add-text-to-image
https://www.geeksforgeeks.org/java-program-to-add-text-to-an-image-in-opencv/
I want to display an image in the web application where user can add text on the image.
Finally i need to save in DB, later user has to view the editable text and edit if required
How to achieve this in java web application - UI? back-end? DB (json or image or co-ordinates) ?
Does any opensource can be used in all the levels? Can someone suggest some comments/feedback
URL url = new URL(...); --> FAILS here when i try to download a https image - "javax.imageio.IIOException ... "Can't get input stream from URL!""
Note:
URL works from browser
URL works in standalone program
URL fails when used in java web application
Question:
- Is any special treatment required to access https image from web app?
- How does it works in standalone program but not via web app though the certs are not installed in local machine?
What is the correct/right approach and what is the underlying differences?
Thanks
Hello. Is there any guidance on using a Scala 2.13 newtype as a path segment parameter?
package object model {
@newtype case class FileId(raw: String)
}and the routes file contains
GET /files/:id controllers.HomeController.getFileContents(id: model.FileId)I wrote a custom binder but I get this error
[error] /play-scala-seed/conf/routes:8:1: class type required but model.FileId.Type found
[error] GET /files/:id controllers.HomeController.getFileContents(id: model.FileId)I have tried using zio-prelude too but I get a similar error. Has anyone else tried this?
