java - spring 验证中的 jsr-303 在没有默认组的情况下验证

Question

是否可以在不指定组的情况下启用字段的默认验证？例如，我有 bean:

class User {    
  @NotEmpty
  private String name;

  @NotEmpty(groups = UserGroup.ShouldHaveSurName.class)
  private String surname;
}

我希望字段“name”在任何情况下都被验证——如果在 Controller 中没有为 @Validated 注释指定组，或者如果指定了“ShouldHaveSurName”组。我相信有这方面的配置，但找不到。

来自 JSR-303 specification :

3.4. Group and group sequence

A group defines a subset of constraints. Instead of validating all constraints for a given object graph, only a subset is validated. This subset is defined by the the group or groups targeted. Each constraint declaration defines the list of groups it belongs to. If no group is explicitly declared, a constraint belongs to the Default group.

所以在 Controller 中执行以下操作就足够了:

@Validated({UserGroup.ShouldHaveSurName.class, Default.class})
