将MTOM与Apache CXF 2.5.2一起使用时，架构验证失败

标签： cxf xml-validation mtom

我正在使用Apache CXF 2.5.2来创建Web服务。我创建了一个端点并使用以下方法启用了mtom和模式验证：

<jaxws:properties>
    <entry key="mtom-enabled" value="true"/>
    <entry key="schema-validation-enabled" value="true"/>
</jaxws:properties>

如果我关闭mtom-enabled属性，则架构会正确验证。如果我关闭schema-validation-enabled属性，则mtom可以正常工作。

<result>
<xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include" href="cid:2fd0125c-bfb6-454b-8a98-9e3a16083dca-9@cxf.apache.org">
</xop:Include>
</result>

我的架构如下所示：

<xsd:complexType name="ResultList">
    <xsd:sequence>
        <xsd:element name="result" type="myns:ResultType"
            minOccurs="0" maxOccurs="unbounded" />
    </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="ResultType">
    <xsd:simpleContent>
        <xsd:restriction base="xmime:base64Binary">
            <xsd:attribute ref="xmime:contentType" use="required" />
        </xsd:restriction>
    </xsd:simpleContent>
</xsd:complexType>

我的Base64Binary类看起来有点像这样：

public class Base64Binary
{
    @Lob @XmlValue
    protected byte[] value;
    @XmlAttribute(namespace = "http://www.w3.org/2005/05/xmlmime")
    protected String contentType;
}

启用架构验证后，我收到以下错误：

有关如何解决此验证错误的任何想法？

谢谢。

1 个答案:

答案 0 :(得分：0)

您可以将“result”元素设置为：

<xsd:element name="result" type="xsd:base64Binary"
        minOccurs="0" maxOccurs="unbounded" />

并看看是否有帮助。从根本上说，JAXB模式验证和mtom并不真正兼容，因为在验证后处理了mtom内容（IMO有点不对）。 CXF确实试图让它一起工作，但我认为它只能在元素类型直接为base64Binary类型的情况下才能实现。
