如何在 Spring 引導中修復“嵌套異常是 java.lang.ArrayIndexOutOfBoundsException：索引 2 超出長度 2 的范圍” - ZE4728F444B24839E3F80ADF3829BCBA

Question

我有一個帶有 PostgreSQL 的 Spring 引導項目，當我嘗試從 UserController 執行 findAll() 方法時出現錯誤。 您可以看到我的用戶 Class 和我返回的錯誤，它與查詢有關，但我找不到它。 我還使用了擴展 JpaRepository 的 UserRepository 我可以執行 findById 方法，但我在 findAll() 中遇到了這個問題。

package com.application.vehicleRepairShop.domain;


@Entity

@Table(name = "users", schema = "vehicleproject")

枚舉

public enum UserType {

}

SQL 表

CREATE TABLE vehicleproject."roles" (

Answer 1

異常發生在EnumJavaTypeDescriptor.fromOrdinal 。 所以我的猜測是您在database列中的role_id值為2。

但是UserType枚舉中只有兩個值：ADMIN和USER。 ADMIN的序數為0，而USER的序數為1。因此，如果您的行在user_type列中包含2，則它對於UserType枚舉是無效的序數。

Answer 2

請檢查您的數據庫值應該是 0,1
