在Spring MVC中不使用@Valid验证POJO

Question

我需要使用注释@Valid作为方法的参数来验证POJO，不带。

我在这一点上陷入困​​境：

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set<ConstraintViolation<Menu>> constraintViolations=validator.validate(menu);
    //Menu is my Pojo

    if (!constraintViolations.isEmpty()) {
        Iterator itr = constraintViolations.iterator();
        while(itr.hasNext()){
            Object o = itr.next();
        }               
    }

它似乎有效，因为内部＆＃34; itr＆＃34;我有这样的东西::

oConstraintViolationImpl{interpolatedMessage='size must be between 3 and 50', propertyPath=titolo, rootBeanClass=class com.springgestioneerrori.model.Menu, messageTemplate='{javax.validation.constraints.Size.message}'}

现在，我的问题是：如何添加＆＃34; itr＆＃34;值BindingResult ???可能我应该投一些东西......不知何故......

谢谢

Answer 1

@Test
public void testBindingResult(BindingResult result,Set<ConstraintViolation<String>> violations){
    for (  ConstraintViolation<String> constraintViolation : violations) {
        ObjectError error=new ObjectError("object",constraintViolation.getMessage());
        result.addError(error);
    }
}

你应该创建ObjectError here类型的对象是该类的spring文档，你应该将它添加到绑定结果。
