java - JaxB 验证事件定位器 - 错误的对象引用

Question

我只是想问以下问题:
奥 git _a
奥 git _a

我遇到了类似的问题，所以我尝试了这些解决方案，但我发现了一些奇怪的东西:

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 + "]";
    }

}

客户

package com.oner.jaxb.test.entities;

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

import javax.xml.bind.annotation.XmlElement;

public class Customer {

    private String name;

    private List<PhoneNumber> phoneNumbers = 
        new ArrayList<PhoneNumber>();

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @XmlElement(name="phone-number")
    public List<PhoneNumber> getPhoneNumbers() {
        return phoneNumbers;
    }

    public void setPhoneNumbers(List<PhoneNumber> phoneNumbers) {
        this.phoneNumbers = phoneNumbers;
    }

    @Override
    public String toString() {
        return "Customer [name=" + name + ", phoneNumbers=" + phoneNumbers + "]";
    }

}

电话号码

package com.oner.jaxb.test.entities;

public class PhoneNumber {

    @Override
    public String toString() {
        return "PhoneNumber []";
    }

}

JabxbTest

package com.oner.jaxb.test;

import java.io.File;

import javax.xml.XMLConstants;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;

import org.xml.sax.helpers.DefaultHandler;

import com.oner.jaxb.test.entities.Customer;
import com.oner.jaxb.test.entities.Customers;
import com.oner.jaxb.test.entities.PhoneNumber;

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();
        }

    }

}

客户.xsd

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:element name="customers">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="customer"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="customer">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="name" type="stringMaxSize5"/>
                <xs:element ref="phone-number" maxOccurs="2"/>
             </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="phone-number">
        <xs:complexType>
            <xs:sequence/>
        </xs:complexType>
    </xs:element>

    <xs:simpleType name="stringMaxSize5">
        <xs:restriction base="xs:string">
            <xs:maxLength value="5"/>
        </xs:restriction>
    </xs:simpleType>

</xs:schema> 

现在，有趣的是。

当我使用 Java 1.6 运行示例时，得到以下结果

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 'customer'. No child element '{phone-number}' is expected at this point.
Customers [customers=[Customer [name=123456, phoneNumbers=[PhoneNumber [], PhoneNumber [], PhoneNumber []]], Customer [name=234, phoneNumbers=[]]]]
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=[]]]]

使用 Java 1.7

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=[]]]]

我的问题和我的期望:

1. 我看到第一个 Customer 对象出现 2 个错误，均与名称字段长度有关，但为什么我会出现 2 个验证错误？
2. 第二个客户会出现“此时不需要子元素”错误，但它应该是第一个，它有 3 个 PhoneNumber 元素，最多应为 3 个。 2
3. “Customers 元素出现“One of '{phone-number}' is Expected”错误，这可能是可以接受的，但我也预计此错误会持续几秒的 Customer 元素，该元素没有 PhoneNumber 元素，其中 min.是 1
4. Java 7 引发了第二个客户缺少 PhoneNumber 的错误，这很好，但它发现 honeNumber 对象是 Customer。我希望也能看到 Customer 元素。

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

谢谢

经过一番挖掘，我发现了一个有趣的插件，krasa-jaxb-tools，它添加了与 XSD Schame 验证规则等效的 JSR-303 注释。例子似乎很有希望:github repo
