原因：javax.validation.ConstraintViolationException：类验证失败

Question

首先对我的语言感到抱歉，英语不是我的母语

\n\n

任何帮助将不胜感激

\n\n

我正在尝试使用 JPA 开发基本的 Spring Boot 应用程序。我已经完成了项目的大部分内容，并且项目还包括表单验证。每当我尝试添加新的 Person 时，它都运行良好，我可以获得正确的验证来自验证器的消息，我也可以毫无问题地更新此人，但每当我在更新表单中出错时，验证器都会导致此错误

\n\n

Answer 1

根据 App6Controller 中的共享代码片段，在方法 update 中，在更新操作验证错误期间未检查任何条件，因此在保存操作期间 hibernate 验证器会抛出错误。如果没有错误，进行更新操作。
