[英]ErrorPageFilter - Forwarding to error page from request [/mypath] due to exception [java.lang.NullPointerException]
我正在開發由maven構建的SpringBoot REST API應用程序，該應用程序可以在上周運行，但是現在出了點問題。
我可以毫無問題地構建應用程序，然后也可以啟動它。 但是，當我調用一個端點時，總是得到一個指向某些內部類的glassfish和apache的空指針。
這是我得到的錯誤：

有人遇到過同樣的問題嗎？ 如果我能找出問題出在哪里，我會感到非常高興。
好吧，問題在於以前我使用了hibernate.validator包中的@NotBlank驗證批注，然后將其更改為javax.validator包，這引起了問題。 所以我需要從import javax.validation.constraints.NotBlank;改回來import javax.validation.constraints.NotBlank; import org.hibernate.validator.constraints.NotBlank; 在任何使用此驗證的地方。
