Я работаю над Spring batch and SCDF
примером. В этом примере я читаю файл CSV
и загружаю все данные в MySQL
. Я смог успешно загрузить данные в MySQL DB, но пользовательский интерфейс не показывает мне START_TIME
и END_TIME
, даже db не содержит записей.
Я загрузил свой код здесь: https://github.com/JavaNeed/spring-cloud-dataflow-example1.git
