I need upload a file by csv with 10000 lines data.
I used is Spring + Thymeleaf, as per request, I need upload a file by csv with 10000 lines data.Now there is a problem that the system is fine when the data within 8K lines, and as soon as the data over 9k lines, error report as below: ERROR [http-nio-8080-exec-1] org.springframework.boot.web.support.ErrorPageFilter  - Forwarding to error page from request [/upload] due to exception [Exception evaluating SpringEL expression: "session.screenList"] org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "session.screenList" . . . Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1007E:(pos 0): Property or field 'screenList' cannot be found on null
I already expanded my SPRING LIST to over 2W.(binder.setAutoGrowCollectionLimit(20000),) And setting maxparameter = -1 in tomcat.
There is some problems at THYMELEAF or system front, is any possible what is already over the limit? Pls advice, thank you!
PS:And when the data reach to 8000 lines, CCS can not be loading normally
