Ich habe einen Frühling-Batch-Job geschrieben, der aus einer DB liest und dann auf eine CSV schreiben.Spring Batch ItemWriter Erstellen von Ausgabe zweimal
Der Job ist ziemlich einfach und es funktioniert, aber der ItemWriter sieht so aus, als ob er zweimal ausgeführt wird. d. h. ich lande mit zwei CSVs (genau das gleiche) anstelle von einem.
Kann mir jemand helfen, herauszufinden, warum bitte? Dies geschieht mit einer anderen jobExecution.id.
Anbringen Batch-Job und Konsolenausgabe von unten laufen ...
