【中文标题】如何在 Spring Boot 中修复“嵌套异常是 java.lang.ArrayIndexOutOfBoundsException：索引 2 超出长度 2 的范围” - postgresql 项目【英文标题】：How to fix "nested exception is java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2" in a Spring Boot - postgresql Project 【发布时间】：2019-10-29 08:44:58 【问题描述】：我有一个带有 PostgreSQL 的 Spring Boot 项目，当我尝试从 UserController 执行 findAll() 方法时出现错误。您可以看到我的用户类和我返回的错误，它与查询有关，但我找不到它。我还使用了扩展 JpaRepository 的 UserRepository 我可以执行 findById 方法，但我在 findAll() 中遇到了这个问题。

【问题讨论】：
异常发生在 EnumJavaTypeDescriptor.fromOrdinal。所以我的猜测是你在数据库列中的 role_id 值是 2，但是 UserType 枚举中只有两个值（因此它们的序号是 0 和 1）。 @JBNizet ，我用我的枚举类和 2 个表编辑我的问题，但我无法理解冲突。如果你发现了什么，请你看看并告诉我！ UserType 有两个值：ADMIN 和 USER。 ADMIN 的序号为 0，而 USER 的序号为 1。因此，如果您的行在 user_type 列中包含 2，则它是 UserType 枚举的无效序号。 docs.oracle.com/javase/8/docs/api/java/lang/Enum.html#ordinal-- @JBNizet 非常感谢！！！ @JBNizet 请发布您的 cmets 作为答案。我真的厌倦了阅读评论中答案的未回答问题 【参考方案1】：异常发生在EnumJavaTypeDescriptor.fromOrdinal。所以我的猜测是你在数据库列中的 role_id 值是 2。
