Karaf的Moxy误差

Question

我在fuse ESB下使用MOXy (基于karaf)，我将org.eclipse.persistence.jar转换成了一个包，我在fuse ESB下部署了这个包，并得到了这个错误

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

当尝试创建JAXBContext的新实例时，我的代码试图将jaxb.properties模型转换为XML，模型部署在fuse下的一个单独的包中，我在模型的同一个包中添加了jaxb.properties文件。

注意:当从main类中的main方法运行时，相同的代码成功地运行，没有问题。

下面是我的代码，错误发生在第6行上。

    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);

知道吗？

Answer 1

通过替换这段代码已经解决了问题

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");

与

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);

Answer 2

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

EclipseLink 2.4.1组合

• http://www.eclipse.org/downloads/download.php?file=/rt/eclipselink/releases/2.4.1/eclipselink-plugins-2.4.1.v20121003-ad44345.zip

对于EclipseLink JAXB (MOXy)，您需要以下包：

• 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

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

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

更新#1

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

在上面第2行的代码中，我发现在您的答案中提到的eclipse中不推荐使用JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY，对它有什么替代吗？

我们引入了新的类，以便更容易地找到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。

• 以下内容：JAXBContextFactory.ECLIPSELINK_OXM_XML_KEY
• 替换为：JAXBContextProperties.OXM_METADATA_SOURCE

更新#2

我还没有使用过Karaf，但是下面是一个可以在中运行的OSGi示例：

example/Activator.java

我发现您需要使用上下文路径创建JAXBContext。这允许您传入一个ClassLoader。这个类加载器需要知道EclipseLink JAXB (MOXy)实现。我还包括了一个指定MOXy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.index

当从上下文路径创建JAXBContext时，您需要在上下文路径中包含一个名为jaxb.index的文件，其中包含一个以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，需要在与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

下面是清单的一个示例。在本例中，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>
