JAXB 解组单元测试在 Eclipse 中成功，但在 gradle 测试中失败并显示“JAXB 无法处理接口”

问题描述 投票：0回答：1

这是一个单元测试，当我在 Eclipse 中运行它时可以成功运行，但当我使用 gradle 命令行“gradle test”运行它时会失败。

package com.mycompany.user;

import static org.junit.Assert.assertEquals;

import org.junit.Test;

public class ImportUserTest {

    @Test
    public void testUnmarshall() throws Exception {
        ImportUser importUser = new ImportUser();
        UserList userList = importUser.unmarshall("src/test/resources/userList.xml");
        assertEquals("John Doe", userList.getUser().get(0).getFullName());
    }
}

ImportUser 类如下：

package com.mycompany.user;

import java.io.FileInputStream;
import java.io.FileNotFoundException;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.parsers.ParserConfigurationException;

import org.xml.sax.SAXException;

public class ImportUser {

    private static final String PACKAGE_CONTEXT = "com.mycompany.user";

    public UserList unmarshall(String inputFile) throws JAXBException, FileNotFoundException, ParserConfigurationException, SAXException {
        JAXBContext jc = JAXBContext.newInstance(PACKAGE_CONTEXT);
        Unmarshaller u = jc.createUnmarshaller();
        return (UserList) JAXBUtilities.safeUnmarshall(u, new FileInputStream(inputFile));
    }
}

这个JAXBUtilities类如下：

package com.mycompany.user;

import java.io.InputStream;
import java.io.Reader;

import javax.xml.XMLConstants;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.transform.Source;
import javax.xml.transform.sax.SAXSource;

import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class JAXBUtilities {

    private JAXBUtilities() {
    }

    public static Object safeUnmarshall(Unmarshaller u, InputStream in) throws ParserConfigurationException, SAXException, JAXBException {
        return safeUnmarshall(u, new InputSource(in));
    }

    public static Object safeUnmarshall(Unmarshaller u, Reader reader) throws ParserConfigurationException, SAXException, JAXBException {
        return safeUnmarshall(u, new InputSource(reader));
    }
    
    public static Object safeUnmarshall(Unmarshaller u, InputSource inputSource) throws ParserConfigurationException, SAXException, JAXBException {
        SAXParserFactory spf = SAXParserFactory.newInstance();
        spf.setValidating(true);
        spf.setNamespaceAware(true);
        spf.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
        spf.setFeature("http://xml.org/sax/features/validation", false);
        spf.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
        spf.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
        spf.setXIncludeAware(false);

        Source xmlSource = new SAXSource(spf.newSAXParser().getXMLReader(), inputSource);
        return u.unmarshal(xmlSource);
    }
}

XML 输入下方：

<userList>
  <user name="string">
    <fullName>John Doe</fullName>
    <description>BO user</description>
    <lastPropertyNum>3</lastPropertyNum>
    <loginIddleDays>3</loginIddleDays>
    <maxLoginAttempt>3</maxLoginAttempt>
    <maxTrades>3</maxTrades>
    <passwordCheckDigit>true</passwordCheckDigit>
    <passwordCheckSpecialChar>false</passwordCheckSpecialChar>
    <passwordMinLength>3</passwordMinLength>
    <passwordChangeDue>false</passwordChangeDue>
    <thresholdDays>3</thresholdDays>
    <updateUser>string</updateUser>
    <version>3</version>
    <processingOrg>ALL</processingOrg>
  </user>
</userList>

我从下面生成的类中删除了注释（由 JAXB 2.1.3 生成）：

据我了解，下面的错误表明 JAXB 运行时无法猜测接口的正确实现，因为它不知道在许多可能的接口之间应该使用哪一个。

在独立项目中的 Eclipse 中运行时出现的错误如下：

我在 

jaxb.properties
中有 
src/main/java/com/mycompany/user
，必须移至 
src/main/resources/com/mycompany/user
。 事实上，Gradle 会忽略 
src/main/java
中的属性，并且不会将它们复制到构建文件夹中。
