在JAXB中表示多個元素名稱

Question

我有下面的XML代表一個調用事件並需要解組到Java對象。我正在使用JAXB並且能夠處理大部分內容，除了表示值集合的塊作爲元素名稱。

爲每個可能的元素創建一個類的缺點（即給出here）有沒有一種方法可以更動態地在JAXB中表示它？

<message xmlns='jabber:client' from='pubsub.server.example.com' to='leon@server.example.com' 
id='leon_office_vmstsp_default__leon@server.example.com__uz8mQ'> 
<event xmlns='http://jabber.org/protocol/pubsub#event'> 
    <items node='leon_office_vmstsp_default'> 
     <item id='leon_office_vmstsp_default'> 
      <callstatus xmlns='http://xmpp.org/protocol/openlink:01:00:00#call-status' 
       busy='false'> 
       <call> 
        <id>1411743786867</id> 
        <profile>leon_office</profile> 
        <interest>leon_office_vmstsp_default</interest> 
        <changed>State</changed> 
        <state>CallEstablished</state> 
        <direction>Outgoing</direction> 
        <duration>3</duration> 
        <caller> 
         <number>6001</number> 
         <name>leon_office</name> 
        </caller> 
        <called> 
         <number>3807</number> 
         <name>3807</name> 
        </called> 
        <actions> 
         <ClearCall /> 
         <RemoveThirdParty /> 
         <StopVoiceDrop /> 
         <MuteParty /> 
         <AddThirdParty /> 
         <SendDigit /> 
         <ClearConnection /> 
         <UnMuteParty /> 
         <StartVoiceDrop /> 
        </actions> 
        <participants> 
         <participant exten='3807' /> 
         <participant exten='6001' /> 
        </participants> 
        <features> 
         <feature id='Conference'>true</feature> 
        </features> 
       </call> 
      </callstatus> 
     </item> 
    </items> 
</event> 
<headers xmlns='http://jabber.org/protocol/shim'> 
    <header name='pubsub#subid'>aLfatHpG059mNcAe5ta11YNOAjA02l486sE1p4hK</header> 
</headers>

JAXB Java類代

1. 生成您的XML的XSD。您也可以使用this link或其他工具正常工作。
2. 通過XJC生成XSD類，Maven插件see here

下面的連接例子maven-jaxb2-plugin
