私はJobOfferを収集し、手動でそれらに適用することができます私の友達のアプリで書いています。POSTを介してInputStreamからアップロードファイル中のSpringブート、RestTemplate例外
たとえば、私はこのページからCSRFトークンを取得していますClick原因私はファイルをアップロードするためにCSRFが必要です。
しかし、とき、私はエラーになっています)restTemplate.exchangeを(実行しようとしている: 「によって引き起こさ:java.lang.ClassCastExceptionがを:org.springframework.core.io.ByteArrayResourceはjava.langのにキャストすることはできません.String "ここで
は私のクラスである:ここでは
