上面是使用JAXBContext解析出的报文，想把body节点中的xsi:type xmlns:xsi删除，google找出一篇文章，记录之：

Remove xsi:type after marshalling abstract class with hierarchy

If someone help me,that will be great. So I have a structure:

<span style="font-family:Courier New;font-size:12px;"><letters> 
  <list> 
    <name>Simon</name>  
    <type>2</type>  
    <passengerName>Johny</passengerName>  
    <passengerSurname>Revelator</passengerSurname> 
  </list>  
  <list> 
    <name>someName</name>  
    <type>4</type>  
    <fileURL>someUrl</fileURL>  
    <specialNotes>specialNotes</specialNotes> 
  </list> 
</letters></span>

For this structure I wrote Java Classes and they marshall and unmarshall it: Class A package com.edhex.testing;

import javax.xmlbindannotation.*; @XmlAccessorType(XmlAccessTypePROPERTY)@XmlSeeAlso({B.class, C})@XmlType abstractpublicclass A {int type; String name@XmlElement getType() return}void setType(thistype = getName setNamename }

Class Letters:

@XmlRootElementLettersList<A> list getList setListlist  Class B: 
 B extends fileURL specialNotes getFileURL setFileURLfileURL  getSpecialNotes setSpecialNotesspecialNotes  Class C: 
 C  passengerName passengerSurname getPassengerName setPassengerNamepassengerName  getPassengerSurname setPassengerSurnamepassengerSurname  Everything looks fine,but after marshalling which I do like this: 
static mainString[] args C c new(); csetName("Simon");setType(2setPassengerName"Johny"setPassengerSurname"Revelator" B b  B b4setFileURL"someUrl"setSpecialNotes"specialNotes""someName" list ArrayList>(add(cb letter Letters lettersetListlisttryFile file File"C:file.xml"JAXBContext jaxbContext JAXBContextnewInstanceMarshaller jaxbMarshaller  jaxbContextcreateMarshaller jaxbMarshallersetPropertyMarshallerJAXB_FORMATTED_OUTPUTtruemarshalletter fileSystemoutcatchJAXBException eprintStackTrace I get output like this: 
<letters> <list xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:type"c"<name>Lasha</name><type>2</type><passengerName>Johny</passengerName><passengerSurname>Revelator</passengerSurname></list>"b"someName4<fileURL>someUrl</fileURL><specialNotes>specialNotes</specialNotes></letters> 
 Question:How can I remove those: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="b" in each list tag? I know that JAXB will notify me with what type is it using,because originally mapping is using another type (A.class),but I don't need that information. Have somebody any ideas?

 If you use@XmlElementRefon thelistproperty then the element for the item will be based on the@XmlRootElementof the referenced class and then you won't get thexsi:typeattibute. 
@XmlElementRef}
