스키마 유효성 검사 및 xsi : type과 관련된 JAXB 문제

Question

주어진 XML 파일의 유효성을 검사하기 위해 JAXB를 사용하여 XSD를 생성하려고하는데 일부 요소에서 xsi : type 특성에 문제가 있습니다. 나는 네임 스페이스 문제로 여겨지는 것 같지만 정확히 무엇이 잘못되었는지를 알 수 없다. 내가 유효성을 검사 할 때

내가 나에게 힌트 UIDataConnection

Fehler: cvc-elt.4.2: Cannot resolve 'UIDataConnection' to a type definition for element 'UIData'. 

의 CVC-elt.4.2 오류가 그것은 이것은 XML

<?xml version="1.0" encoding="utf-8"?>

     </UIData> 
     <ConnectionType>Node</ConnectionType> 
    </C> 
    </Connections>

에게하는 네임 스페이스 문제

입니다 여기 내 XSD가 있습니다 :

<xs:schema elementFormDefault="qualified" version="1.0" targetNamespace="http://foo/bar/baz" xmlns:tns="http://foo/bar/baz" xmlns:knsf="http://foo/bar/thing" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

는 클래스 UIDataConnection는 인 UIData

import javax.xml.bind.annotation.XmlAttribute; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 

@XmlRootElement(name = "C") 
public class Connection 
{ 
    @XmlElement(name = "label") 
    private String label; 

    @XmlElement(name = "UIData", type = UIDataConnection.class) 
    private UIDataConnection uiData; 

    @XmlElement(name = "ConnectionType") 
    private String connectionType; 

    @XmlElement(name = "Description") 
    private String description; 
} 

...

import javax.xml.bind.annotation.XmlAttribute; 
public class UIData 
{ 
    @XmlAttribute(name = "column", required = true) 
    private int column; 

    @XmlAttribute(name = "row", required = true) 
    private int row; 

} 

...

이

import javax.xml.bind.annotation.XmlElement; 

public class UIDataConnection extends UIData 
{ 
    @XmlElement(name = "ConnectionAnchor") 
    private String connectionAnchor; 

    @XmlElement(name = "ConnectionAnchorOffset") 
    private double connectionAnchorOffset; 

} 

내 package-info.java가

@XmlSchema(
    namespace = "http://foo/bar/baz", 
    elementFormDefault = XmlNsForm.QUALIFIED, 
    xmlns={ 
     @XmlNs(prefix="knsf", namespaceURI="http://foo/bar/thing"), 
     @XmlNs(prefix="xsi", namespaceURI = "http://www.w3.org/2001/XMLSchema-instance") 
    } 
) 

이 포함되어 확장

XML과 스키마에는 더 많은 UIData 요소가 있지만 여기서는 관련이 없다고 생각합니다.

xsi : type을 올바르게 처리하려면 어떻게해야합니까? package-info에 xsi 네임 스페이스를 정의해야합니까?

Answer 1

XML 스키마는 복합 형 uiDataConnection을 정의하고 XML 문서는 복합 형 UIDataConnection을 참조합니다. @XmlType 주석을 사용하여 클래스가 해당하는 유형 이름을 제어 할 수 있습니다.

@XmlType(name="uiDataConnection") 
public class UIDataConnection extends UIData
