Question

我有一个带有javax.validation验证注释的Spring Boot（JPA / Hibernate）应用程序，当我对实体执行事务时，我会收到这些神秘的例外：

有没有办法自定义这种异常（通过Spring或Hibernate），例如添加对象的标识符？我怎么知道验证失败的对象是哪种（想象一下数百个元素的更新）？

您可以在bean验证注释中设置验证消息：

@Column(name = "name")
@NotNull(message = "{name.NotNull.message}")
@Size(min = 3, max = 9999, message = "{name.Size.message}")
private String name;

设置消息，在资源中创建ValidationMessages.properties，存储错误语句，例如：

name.NotNull.message=Name should not be null

如何向JPA验证例外
