Moxy xml 与具有单独 xml 路径的虚拟道具绑定

Question

是否可以为如下所示的对象创建一个 Moxy xml-bindings oxm 文件。该对象有一个以参数名称为键的 Map，而 Value 将是一个配置值。每个参数都有自己的 xml 路径。问题是我在哪里可以指定虚拟道具的 xml-path？。我可以将密钥用作 xpath 本身。但是，仍然不确定绑定将如何变成...

public class ServiceData{
  String Id;
  String desc;

  @XmlTransient
  private Map<String, Object> parameters= new HashMap<>();

  public Object getCustomProps(String name){
      return parameters.get(name);
  }

  public void putCustomProps(String name, Object value){
    parameters.put(name, value);
  }
}

绑定文件可能如下所示，但是，我对如何为映射中的每个条目分配 xml-路径感到困惑。

<?xml version="1.0" encoding="US-ASCII"?>
<xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm" package-name="net.blah.blah.domain">
<java-types>
    <java-type name="ServiceData">
        <xml-virtual-access-methods get-method="getCustomProps" set-method="putCustomProps" />
        <xml-root-element name="serviceData"/>
        <java-attributes>
            <xml-element java-attribute="id"
                         type="java.lang.String"
                         xml-path="parameters/group[@name='group1']/parameter[@name='param1']/text()"/>

        </java-attributes>
    </java-type>
</java-types>

我能够通过以下绑定完成此操作。我选择了 json 绑定，因为这是我实际需要的，但是，它也类似于 XML 绑定。

{
  "package-name": "net.company.demo",
  "xml-schema": {
    "element-form-default": "QUALIFIED",
    "namespace": "http://www.example.com/customer"
  },
  "java-types": {
    "java-type": {
      "name": "Pojo",
      "xml-virtual-access-methods": {
        "get-method": "get",
        "set-method": "set"
      },
      "xml-root-element": {
        "name": "rootElement"
      },
      "java-attributes": {
        "xml-element": {
          "java-attribute": "message",
          "type": "java.lang.String",
          "xml-path": "/params/parameter[@name='message']/text()"
        },
        "xml-element": {
          "java-attribute": "shouldValidate",
          "type": "java.lang.String",
          "xml-path": "/params/parameter[@name='validate']/text()"
        },
        "xml-element": {
          "java-attribute": "buffer",
          "type": "java.lang.String",
          "xml-path": "/params/parameter[@name='buffer']/text()"
        }
      }
    }
  }
}

Pojo

public class Pojo{

private String id;

private Map<String, Object> data = new HashMap<String, Object>();

public Object get(String name){
    return data.get(name);
}

public void set(String name, Object value){
    data.put(name, value);
}

}

应用程序代码看起来像

        final Map<String, Object> jaxbContextProps = new HashMap<String, Object>();
    jaxbContextProps.put(JAXBContextProperties.OXM_METADATA_SOURCE, "binding.json");
    jaxbContextProps.put(JAXBContextProperties.MEDIA_TYPE, "application/xml");

    final Map<String, Object> marshallerProps = new HashMap<String, Object>();
    marshallerProps.put(Marshaller.JAXB_FORMATTED_OUTPUT, true);

    final Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setLazyInit(true);
    marshaller.setClassesToBeBound(Pojo.class);
    marshaller.setJaxbContextProperties(jaxbContextProps);
    marshaller.setMarshallerProperties(marshallerProps);

    Pojo pojo = new Pojo();
    pojo.set("message", "This is some message");
    pojo.set("shouldValidate", "Yes");
    pojo.set("buffer", "1000");

    StringWriter writer = new StringWriter();
    StreamResult streamResult = new StreamResult(writer);
    marshaller.marshal(pojo,  streamResult);
    //System.out.println(writer.toString());
