如何使用 JPA 验证器验证 AWS ARN

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

问题描述

如何使用 JPA 验证器和 Hibernate 作为提供者来验证 AWS ARN。 我们是否应该使用正则表达式模式

例如，我们希望确保它以arn:aws:iam开头，用于以下角色

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

使用@Pattern注释并编写一个仅匹配有效 ARN 的正则表达式。 另请参阅https://docs.jboss.org/hibernate/beanvalidation/spec/2.0/api/javax/validation/constraints/Pattern.ZFC35FDC70D5FC69D269883A82
