Karaf 的 Moxy 错误

【问题标题】：Moxy error with KarafKaraf 的 Moxy 错误
【发布时间】：2012-10-08 05:00:33
【问题描述】：

我在 fuse ESB 下使用 MOXy（基于 karaf），我将 org.eclipse.persistence.jar 转换为一个包，我在 fuse ESB 下部署了这个包，我得到了这个错误

Error : "org.apache.cxf.interceptor.Fault: property "eclipselink-oxm-xml" is not supported"

当尝试创建 JAXBContextmy 代码的新实例时，我的代码尝试将 Java 模型转换为 XML，并且模型部署在 fuse ESB 下的单独包中，我在模型的同一包中添加了 jaxb.properties 文件

注意：从主类中的主方法运行时，相同的代码可以成功运行，没有问题。

以下是我的代码，错误发生在 第 6 行。

    Map<String, Source> metadataSourceMap = new HashMap<String, Source>();      
    InputStream is = getClass().getClassLoader().getResourceAsStream
            ("com/syngenta/mint/security/service/transformation/User.xml");             

    metadataSourceMap.put("com.syngenta.mint.security.model",new StreamSource(is));

    1. Map<String, Object> properties = new HashMap<String, Object>();
    2. properties.put(JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY,
            metadataSourceMap);
    3. properties.put("javax.xml.bind.context.factory",
                 "org.eclipse.persistence.jaxb.JAXBContextFactory");

    4. Class[] classes = new Class[1];
    5. classes[0] = User.class;

    6. JAXBContext jc = JAXBContext.newInstance(classes, properties);

有什么想法吗？

    【解决方案1】：

    您可以从以下位置下载我们预构建的 OSGi 包，而不是将 eclipselink.jar 转换为包：

    EclipseLink 2.4.1 捆绑包

    对于EclipseLink JAXB (MOXy)，您将需要以下捆绑包：

    • org.eclipse.persistence.moxy_2.4.1.v20121003-ad44345.jar
    • org.eclipse.persistence.core_2.4.1.v20121003-ad44345.jar
    • org.eclipse.persistence.asm_3.3.1.v201206041142.jar

    如果您使用 MOXy 的 JSON 绑定（请参阅：http://blog.bdoughan.com/2011/08/json-binding-with-eclipselink-moxy.html），您还需要以下捆绑包：

    • org.eclipse.persistence.antlr_3.2.0.v201206041011.jar

    更新 #1

    在 OSGi 环境中，您需要确保导入 MOXy 包或 org.eclipse.persistence.jaxb 包。

    我上面代码第 2 行的另一个问题，我发现 JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY 在 您在回答中提到的日食捆绑包，有没有 替换它？

    我们引入了新类，以便更轻松地查找 JAXBContext、Marshaller 和 Unmarshaller 上的属性。这些类称为JAXBContextProperties、MarshallerProperties 和UnmarshallerProperties，可以在org.eclipse.persistence.jaxb 包中找到。

    • 以下：JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY
    • 被替换为：JAXBContextProperties.OXM_METADATA_SOURCE

    更新 #2

    我没有使用过 Karaf，但下面是一个我可以在 Eclipse Equinox 中运行的 OSGi 示例：

    example/Activator.java

    我发现您需要使用上下文路径创建JAXBContext。这允许您传入ClassLoader。此类加载器需要了解 EclipseLink JAXB (MOXy) 实现。我还包含了一个指定 MOXy 的外部映射文档的示例。

    package example;

import java.util.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextProperties;
import org.osgi.framework.*;

public class Activator implements BundleActivator {

    private static BundleContext context;

    static BundleContext getContext() {
        return context;
    }

    public void start(BundleContext bundleContext) throws Exception {
        Activator.context = bundleContext;

        Map<String, Object> properties = new HashMap<String, Object>(1);
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE,
                "example/oxm.xml");
        JAXBContext jc = JAXBContext.newInstance("example",
                Customer.class.getClassLoader(), properties);

        Customer customer = new Customer();
        customer.setName("Jane Doe");

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(customer, System.out);
    }

    public void stop(BundleContext bundleContext) throws Exception {
        Activator.context = null;
    }

}

    example/jaxb.in​​dex

    从上下文路径创建JAXBContext 时，您需要在上下文路径中包含一个名为jaxb.index 的文件，并用回车分隔的短类名列表。

    Customer

    example/jaxb.properties

    要将 MOXy 指定为您的 JAXB 提供程序，您需要在与您的域模型相同的包中包含一个名为 jaxb.properties 的文件，其中包含以下条目：

    javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

    example/oxm.xml

    下面是一个示例 MOXy 映射文档。

    <?xml version="1.0" encoding="UTF-8"?>
<xml-bindings
    xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
    package-name="example">
    <java-types>
        <java-type name="Customer">
            <xml-root-element/>
             <java-attributes>
                <xml-element java-attribute="name" xml-path="personal-info/name/text()"/>
            </java-attributes>
        </java-type>
    </java-types>
</xml-bindings>

    META-INF/MANIFEST.MF

    以下是清单的示例。在这个例子中，我使用了包导入：

    Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Example
Bundle-SymbolicName: Example
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: example.Activator
Import-Package: org.osgi.framework;version="1.3.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Require-Bundle: org.eclipse.persistence.antlr,
 org.eclipse.persistence.asm,
 org.eclipse.persistence.core,
 org.eclipse.persistence.moxy,
 javax.xml.bind

    输出

    下面是运行Activator的输出：

    <?xml version="1.0" encoding="UTF-8"?>
<customer>
   <personal-info>
      <name>Jane Doe</name>
   </personal-info>
</customer>

    【讨论】：

    • 我使用了前三个包而不是将 eclipselink.jar 转换为包，我得到了同样的错误（org.apache.cxf.interceptor.Fault: property "eclipselink-oxm-xml" is not支持”），有什么想法吗？
    • @eman - 你使用了哪个版本的 EclipseLink 包？
    • 我使用以下包：org.eclipse.persistence.moxy_2.4.1.v20121003-ad44345.jar org.eclipse.persistence.core_2.4.1.v20121003-ad44345.jar org.eclipse.persistence。 asm_3.3.1.v201206041142.jar 我从这个链接下载了它们eclipse.org/downloads/download.php?file=/rt/eclipselink/…
    • 我的代码中的另一个问题在第 2 行，我发现 JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY 在您在回答中提到的 Eclipse 捆绑包中已弃用，是否有任何替代品？
    • 1. @Blaise - 我导入了 org.eclipse.persistence.jaxb 包，我得到了同样的错误，是否应该导入其他包？
    【解决方案2】：

    已通过替换这段代码解决了问题

    Map<String, Source> metadataSourceMap = new HashMap<String, Source>();      
InputStream is = getClass().getClassLoader().getResourceAsStream("com/syngenta/mint/security/service/transformation/User.xml");               metadataSourceMap.put("com.syngenta.mint.security.model",new StreamSource(is));
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY,metadataSourceMap);
        properties.put("javax.xml.bind.context.factory","org.eclipse.persistence.jaxb.JAXBContextFactory");

    有 

    InputStream is = getClass().getClassLoader().getResourceAsStream("com/syngenta/mint/security/service/transformation/User.xml");    
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, is);
