Java JaxB验证事件定位器-错误的对象引用

我只是想问以下问题：

我也有类似的问题，所以我尝试了这些解决方案，但我发现了一些奇怪的问题：

客户验证

package com.oner.jaxb.test;
import javax.xml.bind.ValidationEvent;
import javax.xml.bind.ValidationEventHandler;
public class CustomerValidator implements ValidationEventHandler {

    @Override
    public boolean handleEvent(ValidationEvent event) {
        System.out.println(event.getMessage());
        System.out.println(event.getLocator().getObject());
        return true;
    }
}

客户

package com.oner.jaxb.test.entities;

import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customers {

    private List<Customer> customers = 
            new ArrayList<Customer>();

    @XmlElement(name="customer")
    public List<Customer> getCustomers() {
        return customers;
    }

    @Override
    public String toString() {
        return "Customers [customers=" + customers + "]";
    }

}

jabxtest

package com.oner.jaxb.test;

import java.io.File;

import javax.xml.XMLConstants;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;

public class JaxbTest {

    public static void main(String[] args) {

        Customers customers = new Customers();

        Customer customer1 = new Customer();
        customer1.setName("123456");
        customer1.getPhoneNumbers().add(new PhoneNumber());
        customer1.getPhoneNumbers().add(new PhoneNumber());
        customer1.getPhoneNumbers().add(new PhoneNumber());

        customers.getCustomers().add(customer1);

        Customer customer2 = new Customer();
        customer2.setName("234");

        customers.getCustomers().add(customer2);

        try {

            SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 
            Schema schema = sf.newSchema(new File("resources/customer.xsd"));

            JAXBContext jc = JAXBContext.newInstance(Customers.class);
            Marshaller marshaller = jc.createMarshaller();
            marshaller.setSchema(schema);
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

            CustomerValidator customerValidator = new CustomerValidator();
            marshaller.setEventHandler(customerValidator);

            marshaller.marshal(customers, new DefaultHandler());


        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

customer.xsd

            <xs:maxLength value="5"/>
        </xs:restriction>
    </xs:simpleType>

</xs:schema> 

使用Java1.7

cvc-maxLength-valid: Value '123456' with length = '6' is not facet-valid with respect to maxLength '5' for type 'stringMaxSize5'.
Customer [name=123456, phoneNumbers=[PhoneNumber [], PhoneNumber [], PhoneNumber []]]
cvc-type.3.1.3: The value '123456' of element 'name' is not valid.
Customer [name=123456, phoneNumbers=[PhoneNumber [], PhoneNumber [], PhoneNumber []]]
cvc-complex-type.2.4.d: Invalid content was found starting with element 'phone-number'. No child element is expected at this point.
PhoneNumber []
cvc-complex-type.2.4.d: Invalid content was found starting with element 'customer'. No child element is expected at this point.
Customer [name=234, phoneNumbers=[]]
cvc-complex-type.2.4.b: The content of element 'customer' is not complete. One of '{phone-number}' is expected.
Customers [customers=[Customer [name=123456, phoneNumbers=[PhoneNumber [], PhoneNumber [], PhoneNumber []]], Customer [name=234, phoneNumbers=[]]]]

我的问题和期望：

我看到first Customer对象有两个错误，都是关于名称字段长度的，但为什么我会有两个验证错误

第二个客户出现了“此时不需要子元素”错误，但应该是第一个客户，该客户有3个PhoneNumber元素，最多2个

对于Customers元素，可能会出现“其中一个{phone number}”错误，这可能是可以接受的，但对于seconds Customer元素，我也会出现此错误，它没有PhoneNumber元素，其中min.是1

Java 7因第二个客户上缺少PhoneNumber而引发错误，这很好，但它找到的honeNumber对象就是该客户。我也希望看到客户元素

有人能告诉我发生了什么事吗？ValidationEventLocator工作正常还是我对JaxB期望过高

谢谢

经过一番挖掘，我发现了一个有趣的插件krasa jaxb tools，它添加了JSR-303注释，相当于XSD Schame验证规则。示例似乎很有希望：

我认为您对JAXB的期望太高了。模式和模式派生类之间有很好的距离。有时候，你的模型会被扭曲，以至于你几乎认不出来。我不会依赖模式验证来推断对象结构中的错误。不过，这是一个很好的问题。好吧，这就是我目前正在做的事情，但不知何故，我希望像javax.validation一样使用JaxB验证，但这似乎是不可能的。我想我最好的选择是使用javax.validation注释对这些字段进行注释并对其进行验证。但这也意味着双重工作+每次模式规则更改时，我也需要将其应用于验证规则。如果这有帮助（不确定），您可以使用我的

jaxb2注释插件

，它可以向模式派生类添加任意注释。@lexicore，我发现了另一个有趣的插件，krasa jaxb tools，它添加了JSR-303注释，相当于XSD Schame验证规则。有趣。请考虑就此问题提出答案。
