英文:
Define in XSD a list of byte arrays
问题
在我的DTO中，我有一个变量List<byte[]> attachmentList，我想在XSD中对其进行建模。到目前为止，我有：
<xs:element name="attachmentList" type="AttachmentList">
</xs:element>
<!-- 更多代码在这里 -->
<!-- 字节数组的列表 -->
<xs:complexType name="AttachmentList">
<xs:sequence>
<xs:element name="documents" type="ByteArray" nillable="true">
</xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="ByteArray">
<xs:sequence>
<xs:element maxOccurs="unbounded" name="byteArrayElement" type="xs:byte"/>
</xs:sequence>
</xs:complexType>
不幸的是，在由JAXB生成的类中，它会显示为protected AttachmentList attachmentList;，AttachmentList包含protected ByteArray documents;，最终ByteArray类包含protected List<Byte> byteArrayElement;，这也是不正确的。您应该如何在XSD中正确定义字节数组的列表？
英文:
In my DTO I have a variable List<byte[]> attachmentList and I would likt to model it in XSD. So far I have:
<xs:element name="attachmentList" type="AttachmentList">
</xs:element>
<!-- more code goes here -->
<!-- List of ByteArrays -->
<xs:complexType name="AttachmentList">
<xs:sequence>
<xs:element name="documents" type="ByteArray" nillable="true">
</xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="ByteArray">
<xs:sequence>
<xs:element maxOccurs="unbounded" name="byteArrayElement" type="xs:byte"/>
</xs:sequence>
</xs:complexType>
Unfortunately, in the class generated by JAXB it is then displayed as protected AttachmentList attachmentList; , the AttachmentList contains protected ByteArray documents; and then finally the ByteArray class contains protected List<Byte> byteArrayElement;, which is also incorrect. How shall I correctly define in XSD a list of byte arrays?

得分: 1
byte[]的正确类型是xs:base64Binary。
这意味着字段 List<byte[]> attachmentList 的XSD应该简单地是：
<xs:element name="attachmentList" type="xs:base64Binary" minOccurs="0" maxOccurs="unbounded"/>
英文:
The correct type for a byte[] is xs:base64Binary.
That means the XSD for a field List<byte[]> attachmentList should simply be:
<xs:element name="attachmentList" type="xs:base64Binary" minOccurs="0" maxOccurs="unbounded"/>
