在Moxy中使用外部映射文件覆蓋@XmlTransient行爲

Question

爲什麼我無法使用外部映射覆蓋「type」屬性爲非瞬態，如下所示？當我序列化時，我沒有看到「type」元素。

public class PhoneNumber 
{ 
    private String type; 

    @XmlTransient 
    public String getType() 
    { 
     return type; 
    } 

    //other properties 
} 

我使用「xml-attribute」指定了「type」，希望這將優先於註釋，但它不起作用。

<java-type name="PhoneNumber"> 
     <java-attributes> 
      <xml-attribute java-attribute="type" /> 
      <xml-value java-attribute="number" /> 
     </java-attributes> 
</java-type>

您似乎遇到了錯誤。您可以通過下面的鏈接跟蹤在這個問題上我們的進展：

替代方法

你可以指定字段訪問應該用於PhoneNumber類。

<java-type name="PhoneNumber" xml-accessor-type="FIELD"> 
     <java-attributes> 
      <xml-attribute java-attribute="type" /> 
      <xml-value java-attribute="number"/> 
     </java-attributes> 
    </java-type>

import javax.xml.bind.annotation.XmlTransient; 

public class PhoneNumber { 
    private String type;

個jaxb.properties

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

演示

package forum11991936; 

import java.util.*; 
import javax.xml.bind.JAXBContext; 
import javax.xml.bind.Marshaller; 

import org.eclipse.persistence.jaxb.JAXBContextProperties; 

public class Demo { 

    public static void main(String[] args) throws Exception { 
     Map<String, Object> properties = new HashMap<String, Object>(); 
     properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, "forum11991936/oxm.xml"); 
     JAXBContext jc = JAXBContext.newInstance(new Class[] {PhoneNumber.class}, properties); 

     PhoneNumber pn = new PhoneNumber(); 
     pn.setType("cell"); 
     pn.setNumber("555-1111"); 

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

輸出

<?xml version="1.0" encoding="UTF-8"?> 
<phone-number type="cell">555-1111</phone-number>
