推荐答案

The JSR 303 default message interpolation algorithm allows you to customize messages by supplying a resource bundle named ValidationMessages. Create a ValidationMessages.properties file in the classpath containing:

javax.validation.constraints.NotNull.message=CUSTOM NOT NULL MESSAGE
javax.validation.constraints.Size.message=CUSTOM SIZE MESSAGE

这会更改@Size约束的默认消息，因此您应该使用@Size约束，而不是特定于Hibernate的@Length约束.

This changes the default message for the @Size constraint, so you should use the @Size constraint instead of the Hibernate-specific @Length constraint.

您可以更改特定约束实例的消息，而不是更改所有约束的默认消息.在约束上设置message属性:

Instead of changing the default message for all constraints, you can change the message for a specific constraint instance. Set the message attribute on the constraint:

@NotNull(message = "{email.notnull}")
private String email;

并将消息添加到ValidationMessages.properties文件:

email.notnull=E-mail address is required
