如何使用 JPA 驗證器驗證 AWS ARN

[英]How to validate a AWS ARN using JPA validator

問題描述

如何使用 JPA 驗證器和 Hibernate 作為提供者來驗證 AWS ARN。 我們是否應該使用正則表達式模式

例如，我們希望確保它以arn:aws:iam開頭，用於以下角色

arn:aws:iam::344492858010:role/ABC_role
arn:aws:iam::355433858011:role/DEF_role

使用@Pattern注釋並編寫一個僅匹配有效 ARN 的正則表達式。 另請參閱https://docs.jboss.org/hibernate/beanvalidation/spec/2.0/api/javax/validation/constraints/Pattern.ZFC35FDC70D5FC69D269883A82
