Jaxb2Marshaller模式验证似乎不起作用

我经历过Jaxb2Marshaller在进行解组时无法验证我对XSD的无效XML.我正在使用Spring 4.0.0.RELEASE和Java 7.

这是一个例子:

XSD文件:fruit.xsd

我使用Spring Tool Suite从这个XSD生成了JAXB POJO来com.testraptor.xml.jaxb打包.

我的XML文件无效:invalid.xml

如你所见,我打破了架构,因为在水果标签中有一个选择,我同时使用了香蕉和苹果.

我的Spring配置文件:app-config.xml

要测试的主要类:Main.java

package com.fruit.test;

import java.io.IOException;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;

import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;
import org.xml.sax.SAXException;

import com.fruit.xml.jaxb.Fruit;

public class Main {

    public static void main(String[] args) {
        ApplicationContext appContext = new ClassPathXmlApplicationContext(
                "app-context.xml");

        //--------------------------------SCHEMA VALIDATION IS OMITTED

        Jaxb2Marshaller jaxb2Unmarshaller = (Jaxb2Marshaller) appContext
                .getBean("marshaller");
        Resource schemaResource = appContext
                .getResource("classpath:fruit.xsd");
        jaxb2Unmarshaller.setSchema(schemaResource);

        Resource xml = appContext.getResource("classpath:invalid.xml");

        try {
            Fruit fruit = (Fruit) jaxb2Unmarshaller.unmarshal(new StreamSource(xml.getInputStream()));
            System.out.println("SCHEMA VALIDATION IS OMITTED:");
            System.out.println("Apple quantity is " + fruit.getApple().getQuantity());
            System.out.println("Banana quantity is " + fruit.getBanana().getQuantity());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //--------------------------------SCHEMA VALIDATION IS PASSED
        SchemaFactory sf = SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema;
        try {
            schema = sf.newSchema(schemaResource.getURL());
            JAXBContext context = JAXBContext.newInstance(Fruit.class);
            Unmarshaller unmarshaller = (Unmarshaller) context.createUnmarshaller(); 
            unmarshaller.setSchema(schema); 
            Fruit fruit2 = (Fruit) unmarshaller.unmarshal(xml.getInputStream());
            System.out.println("SCHEMA VALIDATION IS PASSED:");
            System.out.println("Apple quantity is " + fruit2.getApple().getQuantity());
            System.out.println("Banana quantity is " + fruit2.getBanana().getQuantity());
        } catch (SAXException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JAXBException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }

}

当我运行代码时,我得到以下结果:

INFO: Loading XML bean definitions from class path resource [app-context.xml]
dec. 26, 2013 9:33:22 DE org.springframework.oxm.jaxb.Jaxb2Marshaller createJaxbContextFromContextPath

 - with linked exception:
[org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 24; cvc-complex-type.2.4.d: Invalid content was found starting with element 'apple'. No child element is expected at this point.]
    at ...

正如您所看到的,当Unmarshaller可以验证时,Jaxb2Marshaller忘记验证我的无效XML文件.

任何人都可以告诉我我的代码可能有什么问题吗？
