我使用 JAXB 绑定我的 xsd,然后尝试创建 JAXBContext:
JAXBContext jaxbContext = JAXBContext.newInstance("my package name");
但是 JAXB 给出 180 IllegalAnnotationsException。
大多数异常都有以下消息:
- XXX是接口,JAXB不能处理接口
- XXX 没有无参数默认构造函数
- @XmlAttribute/@XmlValue 需要引用映射到 XML 中文本的 Java 类型。
当我查看生成的类时,它们都不是接口,我不明白为什么 JAXB 将它们解释为接口。
这是 JAXB 报告的错误之一的堆栈跟踪:
com.sc.md.datatypes.schemas.csemessage.EnvelopeType is an interface, and JAXB can't handle interfaces.
this problem is related to the following location:
at com.sc.md.datatypes.schemas.csemessage.EnvelopeType
at protected com.sc.md.datatypes.schemas.csemessage.EnvelopeType com.sc.md.datatypes.schemas.csemessage.cseMessage.envelope
at com.sc.md.datatypes.schemas.csemessage.cseMessage
com.sc.md.datatypes.schemas.csemessage.EnvelopeType does not have a no-arg default constructor.
this problem is related to the following location:
at com.sc.md.datatypes.schemas.csemessage.EnvelopeType
at protected com.sc.md.datatypes.schemas.csemessage.EnvelopeType com.sc.md.datatypes.schemas.csemessage.cseMessage.envelope
at com.sc.md.datatypes.schemas.csemessage.cseMessage
这就是在 xsd 中定义类型的方式:
<xs:complexType name="EnvelopeType">
<xs:sequence>
<xs:element name="Sent" type="DateTimeType"/>
<xs:element name="Identifier" type="String_1_14"/>
<xs:element name="AcknowledgementCode" type="AcknowledgementCodeType"/>
</xs:sequence>
<xs:simpleType name="AcknowledgementCodeType">
<xs:restriction base="xs:string">
<xs:enumeration value="m"/>
<xs:enumeration value="p"/>
</xs:restriction>
</xs:simpleType>
这是我用来生成绑定的 pom.xml:
