Java uploads data in batches, and the results of development environment and production environment are different.

  java, question

Boss asked me to write a batch upload such a function, and then upload the data to Prepaid Refill

I have no problem in the test environment, but the top-up record uploaded to the server is gone.

Then I exported the database under the formal environment and put it on my database to run without any problem.

Moreover, there is no problem with 40 pieces of data uploaded in batch in the official database, and there is no problem with how many pieces are tested.

I’m thinking about whether it is a system configuration problem, please advise. . .

Whether the reading and writing permissions of the folder in the formal environment are not set, to ensure that the directory where the uploaded data is located is writable, linux command: the directory name uploaded by chmod 777.
