HibernateValidator约束为嵌套对象结构内部的字段映射

Question

我下面有来自第三方jar的java外部类，我想针对该类进行bean验证。

**Product.java:**

private String id;
private Boolean active;
private Price price

**Price.java**

private String discountPrice;
private String originalPrice;

下面是相同的休眠验证器

private Validator createMiraklOfferDataValidator() {
        HibernateValidatorConfiguration hibernateValidatorConfiguration = Validation
            .byProvider( HibernateValidator.class )
            .configure();
        ConstraintMapping constraintMapping = hibernateValidatorConfiguration.createConstraintMapping();
        constraintMapping
            .type( Product.class )
            .field("id")
                .constraint(new NotNullDef().message("id should not be null"))

            .field("active")
                .constraint(new NotNullDef())


            .type( Price.class )
                .field("originalPrice")
                    .constraint(new NotNullDef().message("originalPrice should not be null"))

                .field("discountPrice")
                    .constraint(new NotNullDef().message("discountPrice should not be null"))


        Validator validator = hibernateValidatorConfiguration.addMapping(constraintMapping)
            .buildValidatorFactory()
            .getValidator();
        return validator;
    }

对于Price的嵌套类，验证未按预期进行，非常感谢您的帮助。

我认为您的用例已包含在验证程序文档中：https://docs.jboss.org/hibernate/validator/6.0/reference/en-US/html_single/#example-nested-container-element-constraints
